One mole of carbon weighing 12 grams, reacts with one mole of oxygen gas, weighing 32 grams to produce only carbon dioxide, according to the equation:
C+02 - CO2
Which answer correctly describes the amount of carbon dioxide produced?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
