Answer:
The Calvin cycle has four main steps: carbon fixation, reduction phase, carbohydrate formation, and regeneration phase. Energy to fuel chemical reactions in this sugar-generating process is provided by ATP and NADPH, chemical compounds which contain the energy plants have captured from sunlight.
Explanation:
Answer:
- Volume of the solution will increase.
- Molarity will decrease.
Explanation:
Hello,
In this case, for molarity, unit of concentration relating the moles of solute and volume of solution, we have:

Hence, since the given molarity is 0.70M, we first shall infer that by adding more water, that for sure is the solvent, the volume of the solution will increase which will be the first change. Moreover, since the volume and the molarity are in an inversely proportional relationship, as the volume increases the molarity decreases, which is the other change. In addition to the aforementioned statements, the moles of the solute are not modified as just water is added.
Best regards.
Answer:
The methane gas burns
Explanation:
The burning of methane gas is a combustion reaction. Combustion is an exothermic process. For all exothermic processes, ∆H is negative.
Combustion reaction involves the evolution of heat. The energy of reactants is greater than the energy of products hence the excess energy is given off in the form of heat leading to a negative value of the enthalpy of reaction, hence the answer.
