Coal, which is primarily carbon, can be converted to natural gas, primarily ch4, by the following exothermic reaction: c(s)+2h2(g)⇌ch4(g) a. what is the effect of adding more c to the reaction mixture? b. what is the effect of adding more h2 to the reaction mixture? c. what is the effect of raising the temperature of the reaction mixture? d. what is the effect of lowering the volume of the reaction mixture? e. what is the effect of adding a catalyst to the reaction mixture? f. which of the following will favor ch4 at equilibrium?
catalyst to the reaction mixture", "raising the temperature of the reaction mixture", "both adding more h2 to the reaction mixture and lowering the volume of the reaction mixture", "adding more c to the reaction mixture"]

When a constraint is imposed on a reaction system in equilibrium, the system will readjust itself in order to annul the constraint.

The equation of the reaction is; C(s)+2H2(g)⇌CH4(g)

When more C is added to the sytem, the equilibrium position shifts in the forward direction and more CH4 is produced. Similarly, when more H2 is added, the reaction also proceeds in the forward direction.

Since the reaction is exothermic, raising the temperature of the reaction system favors the reverse reaction and more reactants are produced. When the volume is lowered, the reaction shifts in the forward direction where there are less volumes.

A catalyst has no effect on the equilibrium position. The production of CH4 is favored by;

A. The reaction will proceed forward forming more CH4

B. The reaction will proceed forward forming more CH4

C. Since the reaction is exothermic, raising the temperature will cause the reaction to proceed backward, thus forming C and H2.

D. Lowering the volume makes the gas particles to be more close together thereby enhancing their collisions leading to reaction. Therefore the reaction will proceed forward forming more CH4

E. Catalyst only reduce the activation energy so the reaction can proceed faster. The reaction will proceed forward forming.

F. The following will favour CH4 at equilibrium

i. Catalyst to the reaction mixture,

ii. Both adding more H2 to the reaction mixture and lowering the volume of the reaction mixture

iii. Adding more C to the reaction mixture.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
