HCl + NaOh -> H2O + NaCl
No coefficients are needed because the number of atoms are present on each side by default. Mixing an acid and a base always makes water and a salt, thus the sodium chloride.
NaOH + CaCl2 -----> Ca(OH)2 + NaCl
(Sodium Hydroxide)+(Calcium Chloride) (Calcium Hydroxide)+(Sodium Chloride)
The balanced equation is:
2Na + 2H2O --> H2 + 2NaOH
2Na + CaCl2 = 2NaCl + Ca. Just make sure same number of elements are on both sides.

Na2O + H2O ---------> 2NaOH
Ca(OH)2 + Na2CO3 = CaCO3 + 2 NaOH
cacl2 plus na2s equals cas plus
Ca + Cl2 ---> CaCl2
2hcl
2Na + CaCl2 = 2NaCl + Ca. Just make sure same number of elements are on both sides.
2Na + 2H2O -> H2 + 2NaOH
use a better site you dumby and get a life you Elmo
Na2O + H2O ---------> 2NaOH
2Na + 2H2O -------> 2NaOH + H2
Ca(OH)2 + Na2CO3 = CaCO3 + 2 NaOH
P + Na(OH) + H20 = NaH2PO2 + PH3
(Don't forget to balance it) The precipitate here has to be 2NaCl, as Ca(CO3)2 technically dissolves.
i)NaOH + FeCl3 ii) Na2CO3 + CaCl2
cacl2 plus na2s equals cas plus
