Answer:
A.) Absorb and store
Explanation:
The reaction for photosynthesis is:
→
(reaction conditions: light and chlorophyll)
<em>carbon dioxide + water → glucose + water</em>
<em />
This means light energy is <u>absorbed</u> and <u>stored</u> as sugar molecules and energy for the plant
Therefore, the photosynthesis reaction will <u> absorb </u> energy and <u> store </u> it in the chemical bonds.
Answer:
1) 17.5 mL
Explanation:
Hello,
In this case, the reaction between sulfuric acid and potassium hydroxide is:

In such a way, we notice a 1:2 molar ratio between the acid and the base, therefore, at the equivalence point we have:

And in terms of concentrations and volumes:

Thus, we solve for the volume of acid:

Best regards.
Answer :
The correct answer is due to incorrect position of thermometer .
Distillation is process of separating two volatile liquids on the basis of their boiling points .In involves the following set up ( shown in image )
Since the Boiling point is found is 116-117 C which is near to 124 C , also the purity was checked and thermometer was calibrated .
So the only error could be possible is position of thermometer .
The position of bulb of thermometer is very important to get an accurate reading of boiling point .The vapor so formed should touch the side walls of bulb as soon as they are formed .
May be the bulb of thermometer was kept far from the vapors formed by liquid so, s<u>ome of the vapor before reaching to bulb start condensing and their Temperature decreases </u>.
Hence , the temperature shown by thermometer was decrease than actual boiling point due to incorrect position of thermometer.
C. Move one electron from sodium to fluorine, because the element with the smallest amount of valence electrons is the one that give away the electrons, it is easier to add one to seven than it is to add 7 to one. I just learned this in physics, hope it helps! If you need more explaining I can do that.
