Question

Complete and balance the following equations:
(a) NaOH
+
-→ Na2SO4 + H2O
(b) Ca(OH)2 +
-> CaCO3 + H2O​

Answer 1

Answer:

(a) NaOH +SO4 => Na2SO4 + H2O

(b) Ca(OH)2 + CO2 => CaCO3 + H2O

Answer 2

Answer:

(a) NaOH + H2so4 => Na2so4 + H2o

2NaOH + H2so4 => Na2so4 + 2H2o

(b) Ca(OH)2 + Co2 => Caco3 + H2o

Ca(OH)2 + CO2 => Caco3 + H2o
