Hello, I'm having a very difficult time figuring out how to balance Chemical equations, I just can't seem to figure it out on my own unfortunately. I would be really grateful if anyone knowledgable in chemistry could help me with these equations and understanding the step-by-step process on how to balance them. These are a few of the specific ones I am working on:
a) Na+HCl -> NaCl+H22
b) Fe + O2 -> Fe2O3
c) CaCO3 + HCl -> CaCl2 + CO2 + H2O
d) Mg(NO3)2 + K2SO4 -> MgSO4 + KNO3
e) Ca + H2O -> Ca(OH)2 + H2
f) CH4 + O2 -> CO2 + H2O
g) AgNO3 + CaCl2 -> AgCl + Ca(NO3)2
h) LiOH + AlCl3 -> LiCl + Al(OH)3
i) Pb(NO3)2 + NaI -> PbI2 + NaNO3
j) NH3 -> N2+ H2
k) CuCl2 + Al -> Cu + AlCl
