^I meant molar mass of 4* carbons, because there are actually 4 carbons in Sn(CH3CO2)2 Sorry about that.
^I meant molar mass of 3* carbons, because there are actually 3 carbons in Sn(CH3CO2)2

First, determine how much of the 325g is carbon. 324g [(molar mass of 2 carbon)/(molar mass of Sn(CH3CO2)2)] Then, convert grams of C to mole by dividing by C's molar mass. Finally, convert the mole to atoms. You know for every one mole there is 6.022 ×
For the first three, you would have to apply the rational zero theorem then use synthetic division to see if the remainder is zero. For the last two, you would group the terms and factor out a common factor

If the amino acid is changed, the tertiary structure (interaction between R groups) will be changed. As a result, the protein's structure(/folding) and therefore function will be different.

PV=nRT where P= pressure in atm V= volume in L n =(mass of Ar)/(molar mass of Ar) R=0.082058 L atm mol-1 K-1 T= temperature in Kelvins
volume = (length)*(width)*(height) density= mass/ volume
opps yes your formula is correct!
The correct formula: q = mcΔT or c = q/[(m)(ΔT)] http://chemistry.about.com/od/workedchemistryproblems/a/Specific-Heat-Example-Problem.htm
This link is helpful: http://chemistry.csudh.edu/faculty/noel/CHE317L/Extraction%20Experiment.htm read up to X = 8.0 grams of A extracted into the ether. For your question, you would subtract x from 9.81g after you solve for x.
Angle A is 30 more than twice angle B can be written as A = 2B + 30 Because we know that angle A and angle B form a linear pair, we know that A + B = 180 Plug the first equation into the second equation and solve for A. Once you solve for A, plug the know
Molarity (M) = mol / liter = moles/ 1000ml Therefore, 0.8M = 0.8 mol/ 1000 ml Know that the units cancel out to mol: (0.8 mol/1000 ml)*(150ml) = ? mol if you multipy ? mol by the molar mass of NaCl , you would end up with grams of NaCl (? mol)*(__ g/ mol)=

molality = moles of solute/kilograms of solvent notice how the units cancel out to moles of solute: (moles of solute/kg of solvent)*(kg)= moles of solute
1)look at the units. see how this cancels out to give you columb, the SI unit of quantity of electric charge (columb/sec)*(sec) = ? columb 2) divide ? columb by charge on an electron
volume of sphere = 4/3 π r^3 density = mass/volume
2S + 3O2 -> 2SO3 This example should help you. http://www.chem.tamu.edu/class/majors/tutorialnotefiles/limiting.htm
1)Convert 25* Celsius to Kelvin. Celsius + 273.15 = Kelvin Plug the given numbers in this formula and solve for final temperature. q = mcΔT where q = heat energy m = mass c = specific heat ΔT = change in temperature = final temperature - initial
Hint: Two opposite angles of a parallelogram are congruent, meaning they are equal.
If 3/5 of the students (you can also think this as 3 out of 5 students) are girls, how many of the 5 students are boys? Present in fraction form. This is the simplified or reduced fraction. fraction = part/whole = number of boys/ number of students Set the
Yes
volume = length x weight x height the ends of the box are square, so height = weight volume = length x height x height plug in the numbers and solve for height

Independent variable goes on the x-axis, and the dependent variable goes on the y-axis.
Here's the chemical equation, but you need to balance it still: CuCl2 + NaNO3 => Cu(NO3)2 + NaCl The reactant that produces the lesser amount of product is the limiting reagent. Here's an example problem:

The maximum number of moles of AgCl that could be obtained would be the number of moles of AgCl produced by the limiting reagent.
To convert from .95 mol Al to mol H, you would use the coefficients in the balanced equation. Here's an example of a stoichiometry problem: http://www.jiskha.com/science/chemistry/stoichiometry.html
1) impure anything should be depressed and/or broad compared to literature melting range 2) pure anything should be at the literature melting range

Distance= rate*time Distance upstream = distance downstream Time should be converted to hour b/c the units for rate is in /hour. We know the total time so assign one of the times x (upstream time b/c you would only have to solve for x to get its time) and
