If exactly 14.563g of KMnO4 were dissolved to yield 750mL of solution, what is the normality? I know the equivalent weight is 31.61g. This is how much I got. (14.563g/.750L)(1 mol KMnO4/158.03g)(5 e-/1 mol) = .615 This answer does not seem right however....

What volume of .1 N KMnO4 would be required to titrate .56g of K2[Cu(C2O4)2] 2H20? So, my problem is the normality thing and I need a general direction to go in if possible. From my research, the .1 N means that 1/10 of a mole of KMnO4 is dissolved. I kno...

Ok last question for now. Calcium is determined in limestone by precip. CaC2O4, dissolving precip. in H2SO4, and titrating with KMnO4. The precipitate from the limestone sample weighs .4463g requires 32.17mL of .1336 N KMnO4 for titration. Find percentage...

what has to balance in a properly written nuclear transmutation reaction? example: Nitrogen-14 + helium-4 = Oxygen-17 and Hydrogen-one can also be written as: N((alpha particle), p) O does the reaction balance because it needs an alpha particle and an eje...

An elliptical arch is constructed which is 6 feet wide at the base and 9 feet tall in the middle. Find the height of the arch exactly 1 foot in from the base of the arch. looking for direction with what ellipse equation is and how to approach this problem

For this question, they want me to use fundamental trig identities to simplify the expression. The problem is as follows; (tanx/csc^2x + tanx/sec^2x)(1+tanx/1+cotx) - 1/cos^2x I got as far as this; tanx(1/csc^2x + 1/sec^2x)(1+tanx/1+cotx) - sec^2x. I fact...

Paintball guns were originally developed to mark trees for logging. A forester aims his gun directly at a knothole in a tree that is 4.0 m above the gun. The base of the tree is 20 m away. The speed of the paintball as it leaves the gun is 50 m/s. How far...

Dana loads luggage into an airplane using a conveyor belt tilted at an angle of 20°.She places a few pieces of luggage on the belt before it starts to move, then she turns the belt on. It takes the belt 0.70 s to reach its top speed of 1.2 m/s. Does the l...

In a recent study of how mice negotiate turns, the mice ran around a circular 90 degree turn on a track with a radius of 0.15 m. The maximum speed measured for a mouse (mass = 18.5 g) running around this turn was 1.29 m/s. What is the minimum coefficient...

From what I understand since the distance is doubled, it decreases by 4 times. This is because electrical force is a function of 1/r^2. BTW found the answer on yahoo

The reducing agent is what is oxidized and the oxidizing agent is the reduced.

I think that Europe would be definitely under the veil of Nazism. But, the world is a stretch because NO ONE has ever controlled the whole world at once. Genghis Khan and Alexander the Great have probably come the closest. I think that Hitler would be def...

If they did, I guess everyone would be bald with dark thick mustaches and there would be no minorities in any position of power. AKA Aryan Brotherhood members

Okay thank you Bob

Not sure if right but try this. Say .25=2x where .25 is the fraction of his allowance spent on books and 2x is the number of books multiplied by the price of the books. Solve for x. x=0.125

your solution fits if you mean x^2+5x+6 which factors out to (x+3)(x+2)

Just work it out by using diff. factors of 12. Also one binomial will be subtraction and the other addition.

Your answers seem logical and correct

Try Wikipedia but I think the answer is B

@DrBob222 (.56g)(1mol K2[Cu(C2O4)2] 2H20/353.812g)(2 mol C2O4/1 mol K2[Cu(C2O4)2] 2H2O)(2mol KMnO4/5mol C2O4)(1L/.02mol KMnO4)= .063L Does this seem kosher?

sum of pentagon's angles is 540.

Your train of thought is right because thats how i was figuring it. using the buffer solution equation and then following it with the freezing point dep. There may be a shortcut but I cant remember what/how because you have a weak acid with the salt of it...

Yeah we only really touched on it for a lab where we had to find eq. wts of an unknown acid by titrating with a standardized NaOH solution

The rectangle is definitely not 39 by 45 because those two numbers alone = the perimeter. As for the rectangle call the length (x+6) and the width x. Then say that 84=2(x)+2(x+6). solve for x

To keep the language alive and so it does not go extinct from the lack of speakers

(y^2 - 16)/(y^2 - 16) Now since both expressions are the same, set one equal to zero and solve for y. by the way in your explanation you multiplied by 2, but I think you meant to square it instead. I can check your answer if u reply it as well

You are right quadrant 1 is +,+ and then quadrant 4 is +,-

same rules apply solve for the denominator by setting equal to zero, if that doesnt work ill try working it too

Yes that sounds right.

This really seems like common sense. Im sure you have some and know the right answer.

based on the empirical formula and its contents, you can form the structural formula. what do you think the empirical formula is?

1 sq ft = 12in*12in = 144in^2 multiply that amount by 6 to get how many sq inches in sq ft

It depends on how the species has adapted/is adapting to low oxygen. If it is a fish which typically lives with little oxygen, it will experience either an increase in quality of life or will suffer because it cant handle the buildup of oxygen. But if it...

He probably has a fear of having blood drawn and has associated that with the nurse in question. By the way, you need to ask a question next time

They had a bad experience from eating Wendy's food so now everytime they see the sign, they remember their bout of food poisoning and it makes them sick Also, this is not a question

This is identical to your previous post. She becomes nervous when she sees the nurse because the nurse has the object of her fear; needles

Look up Pavlov's experiment for ideas on class. conditioning an example i guess would be everytime you made say a noise, a certain effect happened, like giving someone a mint. And that person getting used to the behavior. Search for the clip from the Tv s...

I agree with Bob

Not 100% sure but maybe just convert the cm of mercury to mmHg because mmHg is a unit of pressure and you got your answer

Go the website called Desmos and input your graph so you can see the behavior. I think you might change your mind

okay cool thanks

T=KW so solve for k to use in question 6=x(18) x=1/3 So T=(1/3)(12) T=4

I answered three of four

The answer is A because direct variation has the equation y=KX

that wont work because it is a pdf that you downloaded not the pdf link for us to view

which ones do you need/want

make a table with an x and y column then input different x values. For each x value, plug into the equation and solve for y. For the graphing, 4 is the slope and 2 is the y-intercept. So, from the y intercept, go up four and over one and repeat. For the o...

Firstly, I don't believe your question makes sense because you are asking to find temperatures for spontaneity but are given std. cond. You would have to find when Delta G is = neg. Do you know Delta H?

Your answer is right if the affected parents genotype is HH. But it could also be Hh. However the non affected parents genotype is hh. So depending on the genotype of the affected adult, she could have a hundred percent chance or a fifty percent chance

To find the center and radius use the formula for the equation of a circle (x-h)^2 + (y-k)^2=r^2 where (h,k) is the center. and then solve for r by plugging in a point for x and y with using the center for h,k btw find the equation by factoring and comple...

i never gave a final answer just as far as i got. oobleck are you able to explain what identities you used to break down that part? I'm just not seeing how it was simpified

80=3x x=speed so 80/3 is your speed. 270=(80/3)x where x is equal to time (270)/(80/3) = time

turn your 60kg into newtons and then use the formula for work. w=fd

Draw a triangle with your one angle as 75 degrees and the two adjacent sides as how far each person walked after 1.5 hrs. Then law of cosines c^2=7.5^2+9^2- 2(9)(7.5)cos75 solve for c

Start by dividing 2024 by 10. Because we have 10 fingers. which is 202.4. This means that we get through each one of our hands completely 10 times. and then this means that we would end with the ring finger.

I believe that you must multiply the probability of getting bifocals (7/50) by itself to get the prob of picking two. (7/50)(7/50) Same idea for single vision correction but use (43/50)(43/50)

Thanks you legend

get each fraction to a common denominator and then add

5/19 i believe could be wrong

So she has 6 total teaspoons she uses 1/4 teaspoon of salt for every batch. To find out how much she can make, figure out how many times 1/4 goes into 6 or you can write a simple equation and solve for the variable ex) 6=.25x

(5 N Earth)/(0.29 N Pluto) = (115 N Earth)/( x N Pluto)

You give a definition for the word in the context it was used. ex) The wall split the country in two. Answer) A wall is a type of barrier

However far it goes in... some cases when it hits bottom

See if 148 lies closer to 140 or 150. Whatever one it is closer to, round to that number

v=at 27m/s=a(7s) a= 27/7= 3.86m/s^2 F=ma F= (1000kg)(3.86m/s^2) = 3860 N FYI I am a physics student rn in college first semester of it. Bear with me if im wrong

x is in absolute value bars. Just saying it will be positive no matter what even if it was negative. Treat it as 2(x) -1

wait are you just wondering what it is or how to graph/solve it?

W=F*D F=ma will solve for force a=9.8m/s^2 9.8*15=F So, (2460/(9.8*15)= D

H1= 2.5 inches H2=2.75 inches H3= 2 inches Total snow accumulation after 10 hrs = H1 + H2+ H3+ .5(H3) + .5(H4) + .5(H5) + .5(H6) + .5(H7) + .5(H8) + .5(H9)

Treat as a trig. problem. At 9 o clock you would have a triangle with a 90 degree angle so (1.5)^2 + (1.2)^2 = C^2 solve for C

Since the genotype in question has the dominant allele B, the rabbit will have black fur

1.6L(1gal/3.78L) = kool aid in gallons. check the conversion factor for liters to gallons

Exponential decay

I am not familiar with the term penetrance. But to find part a, perform a cross between two Hh individuals and it should come out to like 75% like shiny objects.

The fractions are weird because it goes from having a 4 space Punnett square to 16 because of the inclusion of a second trait in the genotype. The majority has both dominant alleles, 3/16 has only one dominant allele. 1/16 is both recessive alleles no dom...

Your answer is? tip: get y by itself on the left side

I believe it is #1

X + (x-22) = 102

No incorrect. Use the formula a^2 + b^2 = c^2. Solve for c

No incorrect. Use a^2 + b^2 = c^2. C is the length of the hypotenuse. So solve for a or b. Plug in 9 as a or b and 12 as c then solve for the unknown

841 would be c^2. You must square root to get c.

D=sqrt((y2 - y1)^2 + (x2 -x1)^2) D=sqrt( 9 + 16) D=5

subtract 29 from both sides. divide each side by 6 6x + 29 =5 6x=-24 -24/6 = x = -4

Cond. probability statements are stated as this: find this such that it is this. th e part after such that is the condituion

It is Geographic Information Systems and what video were u referring to

(8/45) = (4/9)x Solve for x. Probably be easier to put fractions into decimals
