Coal can be used to generate hydrogen gas (a potential fuel) by thefollowing endothermic reaction. C(s) + H2O (g) <==> CO(g) + H2(g)if this reaction mixture is at equilibrium, predict whether each ofthe following will result in the formation of additional hydrogengas, the formation of less hydrogen gas, or have no effect on thequantity og hydrogen gas.(a) adding more C to the reaction mixture(b) adding more H2O to the reaction mixture(c) raising the temperature of the reaction mixture(d) increasing the volume of the reaction mixture(e) adding a catalyst to the reaction mixture(f) adding an inert gas to the reaction mixture

Explanation:

C(s) + H2O (g) <==> CO(g) + H2(g)

(a) adding more C to the reaction mixture

According to Le Chatelier's principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products - formation of additional hydrogen gas.

(b) adding more H2O to the reaction mixture

According to Le Chatelier's principle, adding additional reactant to a system will shift the equilibrium to the right, towards the side of the products - formation of additional hydrogen gas.

(c) raising the temperature of the reaction mixture

Since this reaction is endothermic, heat is a reactant. By Le Chatelier's principle, increasing the temperature will shift the equilibrium to the right, the formation of less hydrogen gas

(d) increasing the volume of the reaction mixture

When the volume of a system is increased (and the temperature is constant), the pressure will decrease. The equilibrium will shift in a direction that increases the number of gas molecules so that the pressure is also increased. A decrease in pressure will: Favour the reaction that increases the number of gas molecules. So formation of additional hydrogen gas

(e) adding a catalyst to the reaction mixture

- have no effect on the quantity of hydrogen gas. It must increases the rate at which the  reaction is completed.

(f) adding an inert gas to the reaction mixture

- have no effect on the quantity of hydrogen gas.

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

it should be all of them because it asks if you included all of those in your answer
