Answer:
Explanation:
Hello,
In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:
Next, using the molar fraction of argon, we compute the moles of argon:
And the moles of methane:
Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:
Regards.
Answer: 1) endothernic
2) Yes absorbed
Explanation:
Decomposition is a chemical reaction in which one reactant gives two or more than two products. All decomposition reactions are endothermic reactions as energy is absorbed to break the bonds.
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and for the reaction comes out to be positive.
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and for the reaction comes out to be negative.
