In photosynthesis, chlorophyll is a reactant. Li ming is right.
Many plants and algae have a green tint because of chlorophyll. Chlorophyll is contained within organisms in structures known as chloroplasts, which are pictured here and arranged inside plant cells under a microscope.
A component that is present at the outset of a chemical reaction is known as a reactant.
In order to convert light energy into chemical energy that can be released through cellular respiration to power the organism's activities, plants and other living organisms use a process called photosynthesis.
The final component of photosynthesis is light energy. Through its chlorophyll-containing green pigments, the plant absorbs this energy. Li Ming is therefore right.

The molality is 0.54 M when 1.34 moles of NaCl is present in 2.47 kg of solvent.
<u>Explanation:</u>
Molality is the measure of how much of amount of solute is dissolved in the solvent. So it is calculated as the ratio of moles of solute to the grams of solvent.
As in this case, the solute is NaCl and solvent is unknown. So the moles of solute is given as 1.34 moles and the mass of solvent is given as 2.47 kg.
Hence,
Thus, the molality is 0.54 M when 1.34 moles of NaCl is present in 2.47 kg of solvent.
Here h2co3 is reduced because it oxidizes nh3
O iodine (I) because scientists use it for a lot of experiments
