Answer:- 29.6 moles of carbon.
Solution:- We have been given with 3.7 moles of 
and asked to calculate the moles of C.
Looking at the formula of the compound, there are 8 carbons in it means 1 mol of he compound has 8 moles of C. So, if we multiply the given moles of the compound by 8 then we get the moles of C.
= 29.6 mol C
Hence. there are 29.6 moles of C in 3.7 moles of .

Given a mole each for iron and magnesium, the number of atoms of each element is equal. Iron has a greater mass due to its greater molecular weight. The correct statement among the choices is D.
Answer:
It increases when the concentration of reactants increases.
Explanation:
Increasing the concentration of reactants in a reaction increases the amount of reacting molecules or ions which would increase the rate of a chemical reaction. Reaction rate does depend on temperature. Increasing temperature also increases reaction rate because particles move faster with the increased kinetic energy to produce more collisions.
C = 0.11 mol
V = 5.65 L
n = ???
n = C*V
n = 0.11 * 5.65
n = 0.622 mols
1 mol of CaCl2 = 40 + 2*35.5 = 111 grams
0.622 mol = x
x = 111 * 0.622
x = 69.0 grams CaCl2
