Answer 1

NH3+H2O=NH4+OH
BaCO3+HNO3=BaNO3+CO2+H2O
KOH+SIO2=K2SiO3(в осадок)+H2O
NaH2PO4+NaOH=Na2HPO4+H2O 
Na+P=NaP
 H2O+O2+NO2=4HNO3

Answer 2

Balancing Chemical Equations

NH3 + H2O = NH4OH The balanced equation for the reaction between ammonia (NH3) and water (H2O) is: 2NH3 + H2O = NH4OH [[8]](http://chem-teacher.ru/wp-content/uploads/2020/01/%D0%98%D1%81%D0%B0%D0%B5%D0%B2-%D0%94.%D0%A1.-%D0%A3%D1%87%D0%B5%D0%B1%D0%BD%D0%B0%D1%8F-%D0%BA%D0%BD%D0%B8%D0%B3%D0%B0-%D0%BF%D0%BE-%D1%85%D0%B8%D0%BC%D0%B8%D0%B8-8-%D0%BA%D0%BB%D0%B0%D1%81%D1%81-2021.pdf).

BaCO3 + HNO3 = Ba(NO3)2 + H2O + CO2 The balanced equation for the reaction between barium carbonate (BaCO3) and nitric acid (HNO3) is: BaCO3 + 2HNO3 = Ba(NO3)2 + H2O + CO2.

KOH + SiO2 = K2SiO3 + H2O The balanced equation for the reaction between potassium hydroxide (KOH) and silicon dioxide (SiO2) is: 2KOH + SiO2 = K2SiO3 + H2O.

NaH2PO4 + NaOH = Na2HPO4 + H2O The balanced equation for the reaction between sodium dihydrogen phosphate (NaH2PO4) and sodium hydroxide (NaOH) is: NaH2PO4 + NaOH = Na2HPO4 + H2O.

Na + P = Na3P The balanced equation for the reaction between sodium (Na) and phosphorus (P) is: 3Na + P = Na3P.

H2O + O2 + NO2 = HNO3 The balanced equation for the reaction between water (H2O), oxygen (O2), and nitrogen dioxide (NO2) is: 4H2O + 2O2 + 4NO2 = 4HNO3.
