Ya, I noticed that too...I reposted what I did clearer, so please look at that version. I wrote down everything I did and were my problem is. Thanks for the help!

Thank you so much...I would have never been able to figure that out. I would have never came up the idea of subtracting the new volume by the old volume...thank you for all your help!!

How many ten thousandths are in one thousandth?

I'm not sure--I don't get it

Thank you Ms. Sue. So if I get this there would be 100 ten thousandths in one hundredths. Am I right?

Thank you!

Here is where I am at so far, maybe I am off some where else. moles of malachite in 1g: 221.12 mw 1g x 1 mole = 0.004522431 221.12 g 0.004522431 moles of malachite moles of CuO produced: 79.55 mw 1 g x 1 mole = 0.01257071 79.55 0.01257071 moles of CuO ratio of moles of CuO produced per moles of malachite decomposed: 0.004522431 / 0.01257071

ou need to know first of all that tanx=sinx/cosx You will also need to know that: sin0=0 sin30=1/2 sin45=sqrt[2]/2 sin60=sqrt[3]/2 sin 90 =1 and cos0=1 cos30=sqrt[3]/2 cos 45=sqrt[2]/2 cos60=1/2 cos90=0 so you can recognize that 1/sqrt[3] corresponds to tan30, since tan30=sin30/cos30 =1/2/sqrt[3]/2 = 1/sqrt[3]

Mystic rose investigation 6 point mystic rose with reversed colours 12 point mystic rose with reversed colours 18 point mystic rose with reversed colours Each person shakes hands with every other person in the room. If there are 6 people then there are 15 handshakes. If there are 12 people in the room, there are 66 handshakes. The Mystic Rose diagram lets you see how to find the formula N * (N-1) /2 that calucates these numbers. The resulting patterns are pleasing to the eye and encourage students to talk about symmetry and pattern. You can download an Excel spreadsheet that will draw rose patterns from 3 to 25 points. Using with students * We do the handshakes, and agree that if you and I shake hands that is one handshake * Then we ask how many people shake hands with you (one less than the number in the room) * Then I draw dots on the board to represent a room with (say) six people in it - and I draw lines between all the six people * We simplify to 2 people (one line) and three people (3 lines) and four people (6 lines) * I show printouts from the spreadsheet with the first 15 patterns * We go back to the idea that we all do one less handshake than the number of people in the room as we can't shake hands with ourselves. Then we say, well, each of us shakes hands with N - 1 people, and then I squeeze out the formula with the final idea that we divide by 2 because of the definition of a handshake. * I have projected the spreadsheet with a time delay so each line takes a second to draw - and the motion has helped people see what is going on * With a handout showing the roses up to 15 it gets easier to see the symmetry and relationships in the patterns The spreadsheet You can download a spreadsheet that will make drawing the roses up to 25 points easy. The spreadsheet contains a macro written in Visual Basic that does the drawing. See the code for the method. * Open the spreadsheet and enable macros when asked * Make sure that the 'select' button on the drawing toolbar is not selected * Click the Rose button to run the macro * Supply a number of points for the rose (max 25) * Then say how many printer's points you want the radius of the diagram to be * After a second or two, your rose will appear * Enable the drawing tools toolbar: View | Toolbars | Drawing * Click the select arrow and drag a box around the whole rose * Copy and paste into Word or PowerPoint as needed * Students can copy and paste into Paint or PaintShop Pro and 'flood fill' the spaces in the patterns to make artwork One of my patterns - copy and paste into Paint Shop Pro and use the flood fill tool to colour in the spaces between the lines

Did I have the correct answers for the examples?

I think they might be right

Is my answer right?

"In 1765 the British Parliament passed the STAMP ACT, which imposed the first direct tax on the American colonies. The revenue measure <b>was intended to help pay off the debt the British had incurred during the French and Indian War and to pay for the continuing defense of the colonies</b>. To Parliament's great surprise, the Stamp Act ignited colonial opposition and outrage, leading to the first concerted effort by the colonists to resist Parliament and British authority."

thankyou, but I am still confused I need step by step instructions because I don't think I got the right answer

In a traditional landscape the horizon line is most visually pleasing at either the top third or bottom third of the picture depending on the subject matter. IF your picture is a seascape about crashing waves and big boats, the horizon would be in the top third (or less of the pciture). But if the picture was about a thunderstorm, and the violence ofthe weather, i would put it in the bottom third of the picture. Hope this helps.

What does a political party do after it wins the election in order to govern?

i think by party it means republicans democrates....

this is what the question tells me without a doubt the primary goal or objective of a political party is to win elections.the winning party can then govern and implement its programs and policies. but whether a party wins or loses the election it has an important role to play in the american govermental system. then it says discuss the role played by the party that wins the election. in other words what does a party do after it wins the election in order to govern?

ok thanks and would the losing parties have any duties

thanks again for all of your help it is greatly appriciated

Thank YOu soo mUch

i think its New York .... Google it you will find some websites i cant really post the the website here so try searching for the question: Dutch explorers settled primarily in what area .......... and you ll see a link that says a brief history

Hey DrBobb i have a question... I am sure what you mean by 4 places... since they are asking for the mass of KIO3 in 100 mL do we not assme its before we add it together with the other solutions?

Oh okay i got confuse i didn't know you were referring to the significant digits.

heat lost by water = heat gained by steel (m Cp dT) water = (m Cp dT) steel mass steel = (m Cp dT) water / (Cp dT) steel mass steel = (125 g) x (4.18 J/gC) x (22.0-21.1 C) / [(0.452 J/gC) x (21.1 - 2.0 C)] = 54.5 g steel *** 2 *** molar heat capacity is J/mole C not J/gC 4.18 J/gC x (18.0 g / mole) = 75.2 J/moleC

KIO3 solution: M x L = 0.000586448 ( 0.025L)= .000146612 mols .000146612 mols KIO3 x (3 mols I2/1 mol KIO3) x (2 mols S2O3^-2/1 mol I2) mols = .000887972 mols S203^2- Then M S2O3^-2 = .000887972 mols/0.02715 L. M = 0.032400 Therefore the Molar mass of Na2S2O3 is 0.032400

.000146612 mols KIO3 x (3 mols I2/1 mol KIO3) x (2 mols S2O3^-2/1 mol I2) mols = .000887972 mols S203^2- Then M S2O3^-2 = .000887972 mols/0.02715 L. M = 0.032400 Therefore the Molar mass of Na2S2O3 is 0.032400

Oh okay that you...and yes i meant molarity

thank*

Moles of S203^2- = (molarity)(volume): =(0.032400 mol/L)(0.053 litres S203^2-) = 0.03240 moles S203^2- Moles if I2 based on Equation #2: Moles I2 = (1/2)( 0.03240 moles S203^2-) = .00086 moles I2 Moles of ClO^- based on Equation #1: Moles ClO-(aq) = (2/3)(.00086 moles I2) = .00057 moles ClO^3- moles of ClO-(aq) = moles of NaOCl .00057 moles ClO^3- = .00057 moles NaOCl NaOCl mass = (molar mass * moles) = (74) (.00057) = 0.04235 g Do we assume this gives us grams of NaOCl per 0.5 mL of bleach solution, since we didn’t divide or multiply 0.0005 L with anything? And to make it NaOCl / 100 mLs of bleach do we multiply the by 100?

Moles if I2 based on Equation #2: Moles I2 = (1/2)( 0.03240 moles S203^2-) = .00086 moles I2 Moles of ClO^- based on Equation #1: Moles ClO-(aq) = (2/3)(.00086 moles I2) = .00057 moles ClO^3- moles of ClO-(aq) = moles of NaOCl .00057 moles ClO^3- = .00057 moles NaOCl NaOCl mass = (molar mass * moles) = (74) (.00057) = 0.04235 g Do we assume this gives us grams of NaOCl per 0.5 mL of bleach solution, since we didn’t divide or multiply 0.0005 L with anything? And to make it NaOCl / 100 mLs of bleach do we multiply the by 100?

= .00086 moles I2 Moles of ClO^- based on Equation #1: Moles ClO-(aq) = (2/3)(.00086 moles I2) = .00057 moles ClO^3- moles of ClO-(aq) = moles of NaOCl .00057 moles ClO^3- = .00057 moles NaOCl NaOCl mass = (molar mass * moles) = (74) (.00057) = 0.04235 g Do we assume this gives us grams of NaOCl per 0.5 mL of bleach solution, since we didn’t divide or multiply 0.0005 L with anything? And to make it NaOCl / 100 mLs of bleach do we multiply the by 100?

Okay its not lettin me post up i dunt knwo why but the answer i got was NaOCl mass = (molar mass * moles) = (74) (.00057) = 0.04235 g Do we assume this gives us grams of NaOCl per 0.5 mL of bleach solution, since we didn’t divide or multiply 0.0005 L with anything? And to make it NaOCl / 100 mLs of bleach do we multiply the by 100?

Eat it.

That makes sense because in this SN1 reaction a E1 reaction competes with the carbocation intermediate and forms a side product...which is 2-methyl-2-butene. But I don't understand why or why not the fraction is included in the product. Is it just because their boiling points are so far apart? Hence, what criteria are used to determine if its included or not? When would something be included?

my teacher wants me to use the characteristics of aggregrate i know that NH3 is a polar molecular and i think P4 is a network aggregrate and i to use this information to answer this question?

thanks so much that was helpful

i think the 1812 the westerners

what!!!!!!!!!!!!!!!! :0

THANKS SO MUCH

is it flood basalt

My professor also said that its water, but he also asked my what else is in the reaction that could potentially act as a base. Is there anyway that phosphoric acid can turn into a base?

please, I really ned help with this.

Thank you (:

So you just multiply by the coefficients of the 2 half reactions? then let's say if you had: Cu^2+ + Zn ==> Cu + Zn^2+ this would give you 1 electron? or if you had Mg + 2AgNO3 ==> 2Ag + Mg(NO3)2 this would give you 2 electrons? because one of the reactions is multplied by 2 and the other by 1? this would give you

Thank you so much! I understand now!

in the 17th century the living quarters for ordianry people were small and cramped with whole families living in 1 or 2 rooms. many other people lived in dire poverty with little or no oppurtunity to improve their lives. people then had a lack of bathing and often wore dirty clothes. also they didn't have time to clean their personal area that much. is this right

-clothing, because back then the clothing were usually worn in dark colours and and were supposed to be covering everything -church services, because back then they were simple and plain, but now they're not -drinking, because back then people used to drink alot mostly the poor because of their lackness to buy the good food, but now people are just drinking casually -gambling, because back then there used to be a lot of gambling which caused alot of troubles -music, because back then the music was religiouus type but now its full of swear words -mild swear words because back then you weren't allowed to utter a single swaer word but now people swear all the time is this right please help, I have tried and tried
