Answer:
C
Explanation:
The final product is an RNA molecule.
Answer:
2257000 J
Explanation:
Applying,
Q = Cₓm.................. Equation 1
Where Q = amount of energy need to boil the water, Cₓ = Enthalpy of vaporization of water, m = mass of water.
From the question,
Given: Cₓ = 2257000 J/kg, m = 1 kg
Substitute these values into equation 1
Q = 2257000×1
Q = 2257000 J
Hence the energy needed to boil all of the water is 2257000 J
The thermochemical reaction for combustion of methane is the balanced chemical equation for the combustion reaction with the enthalpy change and states of the reactants included.
Combustion is when an organic compound reacts with O₂ to yield CO₂ and H₂O.
thermochemical reaction for combustion of methane is as follows;
CH₄(g) + 2O₂(g) --> CO₂(g) + 2H₂O(g) ΔH = -891 kJ/mol
