Answer:
so the third one
Explanation:
During the day, the sun heats up mountain air rapidly while the valley remains relatively cooler. Convection causes it to rise, causing a valley breeze. At night, the process is reversed. During the night the slopes get cooled and the dense air descends into the valley as the mountain wind.
Polar Covalent Bond
This bond exists when atoms that have different electronegativities share electrons in a covalent bond, the electrons are not transferred from one atom to the other as in the case of ionic bond.
Idk but im guessing a. o3
Answer:
Reduced
Explanation:
NAD⁺ is an intermediate electron acceptor, acting as an oxidant (together with FAD⁺) that participates in cellular respiration as a fundamental reagent, gaining a hydrogen atom (H) in this process, becoming NADH which will later be oxidized.
This process of converting NAD⁺ to NADH (and FAD⁺ converted to FADH₂) by gaining a hydrogen atom is called reduction.
Answer:
It takes 7 mol H2 to produce 7 mol H2O
Explanation:
In 2H2O, there's 2 moles of H2 for every 1 mol O2.
So, if oxygen is limiting you'd only be able to produce 2 moles of H2O. I don't know if the question implies that, so it could also be that 7 mol H2 makes 7 mol H2O. Sorry for the confusion, I hope it helps a bit
