Answer 1

Answer:

2HNO3+Ca(OH)2 ---> Ca(NO3)2+2H2O

you put the two on the H2O to make it 2H2O and A two on the HNO3 to make it 2HN03 To make it balanced

hope i could help every one but i'm only one person i've answered 20 (now 21) questions today my goal is to get 4 brainlyest maybe 8 if i'm lucky

Answer 2

Answer:

Reactants:

2HNO3 has 2 H atoms, 2 N atom and 6 O atoms

Ca(OH)2 has 1 Ca atom, 2 O atoms and 2 H atoms

Left side: 4 H atoms, 2 N atoms, 8 O atoms, 1 Ca atom

Products:

Ca(NO3)2 has 1 Ca atom, 2 N atoms, 6 O atoms

2H2O has 4 H atoms (2 x 2), and 2 O atoms

Right side: 1 Ca atom 2 N atoms, 8 O atoms, 4 H atoms
