Answer:
2NaCl+H2SO4-->Na2SO4+2HCl
Explanation:
There are two Na on the right, so put a 2 in front of NaCl on the left. This makes 3 Cl also, so put a 2 in front of HCl on the right. There are already 2 H on the left, so the equation is balanced.
C2H6 is the most polarizable and other two are non-polar molecules
I feel like I know this but I just can't answer it, sorry
C + O2 -> CO2
Oxygen is the excess reactant (doesn’t get used up in reaction, therefore mass of o2 is irrelevant) so use carbon (the limiting reactant) to calculate the mass of CO2
