_____________________________

(a) HNO3 +Ca (OH)2 → Ca(NO3 ) 2 + H2O

— (HNO3) + Ca(OH)2 → Ca(NO3)2 + 2(H2O)

(b) NaOH + H2SO4 → Na2504 + H2O

— 2(NaOH) + (H2SO4) → (Na2SO4) + 2(H2O)

(c) NaCl + AgNO3 → AgCl + NaNO

— (NaCl) + (AgNO3) → (AgCl) + (NaNO3)

Answer 2

Answer:

Balance the following chemical equations:

(a) HNO3 + Ca(OH)2 → Ca(NO3)2 + H2O

(b) NaOH + H2SO4 → Na2SO4 + H2O

(c) NaCl + AgNOs → AgCl + NaNO3

(d) BaCl2 + H2SO4 →BaSO4 + HCl

(a) 2HNO3 + Ca(OH)2 →Ca(NOa)2 + 2H2O

(b) 2NaOH + H2SO4 → Na2SO4 + 2H2O

(c) NaCl + AgNO3 → AgCl + NaNO3

(d) BaCl2 + H2SO4 → BaSO4 + 2HCl.
