Carbon Dioxide environmental gas so as to make carbonic corrosive that is consolidated with water. Carbon dioxide noticeable all around can disintegrate in rain water to frame carbonic corrosive, H2CO3. Carbonic corrosive is a powerless corrosive. It somewhat ionizes to frame hydrogen particles. The hydrogen particles from carbonic corrosive give common rain water a somewhat corrosive pH estimation of 5.6.
Mole ratio is the ratio between the amount in moles of any two compounds involved in a chemical reaction
3
the mole of Fe3O4 is 1 mole while that of Fe is 3 moles from the reacting equation below
Fe + 4 H2O ----> Fe3O4 + 4 H2
therefore the mole ratio of Fe3O4 to Fe is 1:3(answer A)

Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.
Dissolving a solute in a solvent is an endothermic process hence providing heat favors the process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.
