Answer: 16.32 g of 
as excess reagent are left.
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of 
require = 1 mole of
Thus 0.34 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
Moles of left = (0.68-0.17) mol = 0.51 mol
Mass of 
Thus 16.32 g of as excess reagent are left.
P=18000000/6 zeros. not sure how to do rest
It is about equal to the mass of the neutron. So, most people just say that they have the same mass.

Answer: Atoms that make up reactants rearrange into new products
Explanation:
A chemical reaction is the process of breaking down the chemical bonds of the reacting substances which are commonly called as reactants and making new bonds to form new substances commonly called as products.
The products will contain the same atoms as there are in the reactants but the bonds will rearrange to form different substances.
Every chemical reaction is accompanied with absorption or release of energy.
Answer:
C
Explanation:
I'm assuming that you meant to type neutral charge.
Since electrons are negative and protons are positive, having a balanced number of both of these would cause an atom to have a neutral charge.
