Can someone help me with these chemistry problems?
Sulfuric acid reacts with aluminum hydroxide by double replacement. (Balance, please)...
And...
Balance the equation:
Fe2O3+CO ====> Fe+CO2
Thanks in advance...

3H2SO4 + 2Al(OH)3 ---> Al2(SO4)3 + 6H2O
Fe2O3 + 3CO ---> 2Fe + 3CO2

Sodium acetate is likewise utilized in customer heating pads or hand heaters and is likewise utilized in warm ice. Sodium acetate trihydrate crystals melt at fifty 8°C,[citation needed] dissolving of their water of crystallization. even as they're heated to round one hundred°C, and hence allowed to relax, the aqueous answer will change into supersaturated. This answer is able to cooling to room temperature without forming crystals. via clicking on a metallic disc contained in the heating pad, a nucleation centre is formed which motives the answer to crystallize into sturdy sodium acetate trihydrate back. The bond-forming technique of crystallization is exothermic, subsequently warmth is emitted.[3][4][5] The latent warmth of fusion is about 264–289 kJ/kg.[6] compared to some different sorts of warm temperature packs that matter on irreversible chemical reactions, sodium acetate warmth packs will be actually recharged via boiling till all crystals are dissolved; they're frequently reused indefinitely.[citation needed]

3H2SO4 + 2Al(OH)3 ----> Al2(SO4)3 + 6H2O
Fe2O3 + 3CO ----> 2Fe + 3CO2
