balanced.
this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
Yes
Mass
No - they are usually balanced by changing the numbers before the molecules.
Na2SO4+CaCl2 =====> CaSo4+2NaCl
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
2NaCl + H2SO4 ---> 2HCl + Na2SO4
2HCl + Na2SO4 >> 2NaCl + H2SO4
2CH3COONa+H2SO4 ---> 2CH3COOH+Na2SO4
balanced.

The chemical equation is 2Na + H2SO4 --> Na2SO4 + H2
CuSO4 (aq) + Na2CO3 (aq) --> CuCO3 (s) + Na2SO4 (aq)
Mole Ratios
H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O H2SO4 + 2NaOH ------------> Na2SO4 + 2H2O
Conservation of mass.
