CHEMISTRY HELP PLEASE!!!--- BALANCING EQU.

[gfunkballer]

PLEASE HELP ME BALANCE THIS

1.CAN SOMEONE TELL ME HOW TO BALANCE THIS Ca(CO₃)₂ + HCl = CaCl₂ + CO₂ + H₂O? THIS FORMULA SHOULD MEAN THE SAME AS: 'CALCIUM CARBONATE DISSOLVES IN HYDROCHLORIC ACID TO FORM CALCIUM CHLORIDE, CARBON DIOXIDE, AND WATER.

2. Ferrous phosphate reacts with sodium bicarbonate to yield ferrous bicarbonate and sodium phosphate.

3.Cupric hydrogen sulfate reacts with sodium nitrite to yield cupric nitrite and sodium hydrogen sulfate.



Write a balanced equation for each set of reactants



a. Sodium nitrate decomposes
b. Barium nitrate reacts with sodium sulfate
c. Lithium chloride reacts with fluorine gas
d. Butane (C₄H₁₀) burns in oxygen
e. Sulfuric acid reacts with potassium hydroxide
f. Potassium metal reacts with nitrogen gas
g. Hydrogen peroxide decomposes
h. Magnesium metal reacts with lithium perchlorate



THANKS SO MUCH
