Answer:
9 moles of NaNO3 is obtained
Explanation:
The balanced chemical reaction equation for the reaction is;
Al(NO3)3 + 3NaCl-------> 3NaNO3 + AlCl3
Now, we have to determine the limiting reactant. The limiting reactant yields the least amount of NaNO3.
1 mole of Al(NO3)3 yields 3 moles of NaNO3
4 moles of Al(NO3)3 yields 4 * 3/1 = 12 moles of NaNO3
Also,
3 moles of NaCl yields 3 moles of NaNO3
9 moles of NaCl yields 9 * 3/3 = 9 moles of NaNO3
Hence, NaCl is the limiting reactant and 9 moles of NaNO3 is obtained.
Answer:
The total number of atoms is 12 + 22 + 11 = 45, so carbon atoms are 12/45 of the total.
Explanation:
Answer: 65.28 g of 
will be produced from 34.6 g of Al.
Explanation:
To calculate the moles :
The balanced chemical reaction is
According to stoichiometry :
4 moles of 
produce = 2 moles of
Thus 1.28 moles of produce=
of
Mass of ![[tex]Al_2O_3](https://tex.z-dn.net/?f=%5Btex%5DAl_2O_3)
= 
Thus 65.28 g of will be produced from 34.6 g of Al.
