The light reactions stage:

Chemistry

The light reactions stage occurs before the Calvin cycle , requires light energy to work  and releases oxygen through the stomata.

Answer: D) all the above

Explanation

The light reactions stage is one of the two stages which occur during the chemical reaction of photosynthesis.

It is the first stage and second stage is Calvin cycle. So the first option is true which states that the light reactions stage occurs before the Calvin cycle.

In light reactions stage, the light energy of sun is captured by the chloroplast and this energy is the main trigger for starting the light reaction stage between the reactants carbon-di-oxide and water.

So the second option is also true i.e., the light reactions require light energy to work.

In light reaction stage, the water molecules will release oxygen gas from the stomata.

Thus all the options are true for light reactions stage in photosynthesis.

Which element would most likely have a positive electron affinity?
krok68 [10]
I believe the correct answer from the choices listed above is the first option. The element that would most likely have a positive electron affinity would be sodium, Na. Electron affinity is defined as the change in energy of a neutral atom when an electron is added to the atom.

mihalych1998 [28]

Answer:

the first alternative is the answer.

Explanation:

first u choose the longest chian. that is the horizontal chain. then u count the carbon number. then u see if there are alkyls the alkyl is methyl. and it is 1. so, you first write the alkyl number (1) then the alkyl name (methyl) then you write the alkane name (butane) because it consists 5 carbons. hope it helped.

Which equation agrees with the ideal gas law?
photoshop1234 [79]
<span>\frac{(P1)(V1)}{T1}=\frac{(P2)(V2)}{T2} is directly related to the ideal gas law.

The ideal gas law states that:PV=nRT. Rewriting this gives:\frac{PV}{T}=nR. R is the universal gas constant, so its value is fixed. For a given sample, n is the number of moles of the gas, so its value would be fixed too. This means that the value of \frac{PV}{T} would be a fixed constant as well. Therefore, whatever the initial value \frac{(P1)(V1)}{T1} is, it should be equal to the final value \frac{(P2)(V2)}{T2}.</span>
