CaCl2 + _H20 + __ CO2

CaCO3 + 2HCl → CaCl2 + H2O + CO2

Calcium Carbonate + Hydrogen Chloride → Calcium Chloride + Water + Carbon Dioxide

Calcium carbonate is not very soluble in water. This is an acid-base reaction (neutralization): CaCO3 is a base, HCl is an acid.

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g
