Which of the following are products of the light-dependent reactions of photosynthesis that are utilized in the light-independen
1 answer:
Answer:
Explanation:
The photosynthesis equation is:
energy+6CO₂+6H₂O--> C₆H₁₂O₆+6O₂
The reactants are light energy, carbon dioxide, and water. The products are <u>glucose and oxygen.</u>
<u />
The products of photosynthesis become the products of the light-independent reaction called cellular respiration, which creates useable energy. Therefore, the correct answer is oxygen and glucose.

Answer: The balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is .
Explanation:
When a substance tends to gain oxygen atom in a chemical reaction and loses hydrogen atom then it is called oxidation reaction.
For example, chemical equation for oxidation of methane is as follows.
Number of atoms present on reactant side are as follows.
- C = 1
- H = 4
- O = 2
Number of atoms present on product side are as follows.
- C = 1
- H = 2
- O = 3
To balance this equation, multiply by 2 on reactant side. Also, multiply
by 2 on product side. Hence, the equation can be rewritten as follows.
Now, the number of atoms present on reactant side are as follows.
- C = 1
- H = 4
- O = 4
Number of atoms present on product side are as follows.
- C = 1
- H = 4
- O = 4
Since, the atoms present on both reactant and product side are equal. Therefore, this equation is now balanced.
Thus, we can conclude that balanced equation for the complete oxidation reaction that occurs when methane (CH4) burns in air is .
Explanation:
The number acquired by an element after the lose or gain of an electron is called oxidation number.
For example,
Here, oxidation number of Fe(s) is 0 and Fe in is +3.
Oxidation number of O in is 0 as it is present in its elemental state.
The oxidation number of O in is calculated as follows.
Hence, oxidation number of O in is -2.
- The loss of electrons by an element or substance is called oxidation. Here, electrons are being lost by Fe(s) as an increase in oxidation state is occurring. So, Fe(s) is oxidized.
- The gain of electrons by an element or substance is called reduction. Here, electrons are being added to
as a decrease in its oxidation state is occurring. So,
- An element or compound which is being reduced is called oxidizing agent. Here,
- An element or compound which is being oxidized is called reducing agent. Here, Fe(s) is the reducing agent.
