No: In a chemical reaction, the number and type of atoms of each element involved must be the same on both sides of the chemical equation. In the reaction postulated in the question, helium does not appear as a reactant and hydrogen and oxygen do not appear in the products.
cl2o7+h2o
Na+ plus OH- plus H+ equals H2O plus Na+ plus Cl-
5476
liho+h2s=
H2 - hydrogen.
It's a chemical reaction.
C3h8 + 5o2 -> 3co2 + 4h2o
2NaH2 + O2 yields 2Na + 2H2O
Decomposition
Combustion reaction
SO2 plus H2O equals H2SO3 which is Sulfurous Acid. CO2 plus H2O equals H2CO3which is Carbonic Acid. It also forms HNO3 which is nitric acid.
The missing chemicals are 2LiOH + 2LiNO3 = H2O + CO2 + 4LiNO3.
