Answer: <u><em>Option B; It traps light energy and converts it into chemical energy.</em></u>
<h2>
Explanation: This substance is chlorophyll. It is a pigment present in leaves of all plants. It absorbs light energy and provides it to carry out the process of photosynthesis. Light energy is converted into chemical energy, in form of NADPH and ATP, which can be used by plants for photosynthesis.</h2><h2>
</h2><h2>
This pigment is present only in plants, so option A is incorrect.</h2><h2>
</h2><h2>
This pigment only absorbs and transfers energy to other molecules, and is not associated with carbon dioxide directly, so option C and D are also incorrect.</h2>
72g H2O x 1 mol H2O/18.02g H2O = 3.99 mol H2O
To work this out you do 400÷20=20
The answer is d I'm pretty sure because the second one and the first one don't make sense but I'm not 100 percent positive about it not being d ..... sorry if it's wrong.
