Explanation:
Ba(OH)2(aq) + CO2(g) = BaCO3(s) + H2O(l)
Reaction type: double replacement
a. 48.6 is magnesium and 32.0 is oxygen
b. 80.6
c. also 80.6
d. yes, because the product has equal mass to the reactants
ZnO + C → Zn + CO
I don't know what oxidised an reduced means
Rate= 24
Rate = k[A]^2[B]
k= 3, [A]=2M, [B]=2M
Rate= 3×(2)^2×2= 24
Substitute into above
