Answer:

. When green copper carbonate{CuCO3} is heated it decomposes forming copper oxide {CuO} and carbon

When hydrogen gas combines with nitrogen to form Ammonia the following chemical reaction will take place. Our equilibrium reaction will be N2(g) + 3H2(g) ⇔ 2NH3(g) + Heat. In this case, Hydrogen and nitrogen react together to form ammonia.

Dissolving Sodium sulfate and Hydrochloric acid in water will undergo a reversible reaction as follows: Na2SO4 + 2HCL can react to form H2SO4 and 2NaCl and the reverse reaction also occurs. ... While the HCl will merely dissociate to form Hydronium H3O+ and Cl-

When sodium is dropped in cold water, it reacts explosively and burns with a golden yellow flame. The reaction is exothermic and vigourus. It form sodium hydroxide with the liberation of hydrogen gas
