Which of the following equations represents the right chemical process that occurs in photosynthesis? Question 8 options: A) Six
AlexFokin [52]

Six molecules of carbon dioxide plus six molecules of water plus light energy converts to six molecules of oxygen plus sugar, Thus, the correct option is A.

<h3>What is photosynthesis?</h3>

Photosynthesis is the process through which plants use sunlight to create their own nourishment. Through a sequence of reactions, light energy from the sun is turned into chemical energy, which is then stored in the form of food.

In the presence of sunlight, 6 molecules of carbon dioxide (CO2) and 6 molecules of water (H2O) react to form 1 molecule of glucose sugar. During photosynthesis, 6 molecules of oxygen are formed in addition to glucose.

The following is a balanced chemical reaction for photosynthesis:

   

                                     Sunlight

6CO2    +              6H2O  —---------> C6H12O6 +     6O2.

(carbon                (water)                  (glucose)       (oxygen)  

dioxide)

What will be the percentage of potassium-40 remaining after 3.9 billion years?
Papessa [141]
Potassium-40 has a half life of 1.251×billion<span> years</span><span>. To determine the percentage potassium-40 remaining after 3.9 billion years, divide
3.9 by 1.251, = 3.12.

This is the number of times the original amount of potassium-40 reduces by 50%. The remaining percentage is therefore 100%/(3.12 * 2) = 16.03%.</span>
