Given a chemical reaction, methane (CH4) burns in oxygen (O2) to produce carbon dioxide (CO2) and water (H2O). Which of these re
2 answers:
Answer : The correct option is A.
Explanation :
As per the question, in a reaction, two reactants (methane and oxygen) should be present on the left side of the right-arrow and two products (carbon dioxide and water) which are formed in the reaction should be present on right side of the right-arrow.
Therefore, the unbalanced chemical reaction will be,

Explanation:
The light reactions of photosynthesis use water and produce Oxygen, NADPH.
The equation for photosynthesis :
→
The process of photosynthesis in two stages -
- The first stage is called the light reaction in which the light energy from the sun is captured and converted into chemical energy stored in the form of ATP and NADPH
- The second stage is the process of conversion of ATP molecules to sugar or glucose (the Calvin Cycle)
For a light reaction -
Net Input is of, ,
Net Output is of,
Explanation:
Bond order is inversely proportional to the bond length.
In molecule. one nitrogen is double bonded to nitrogen and one oxygen is single bonded to nitrogen and hydrogen bond.
- Bond order between the (N=O) bond is 2 which means that bond length between the (N=O) bond is shorter than that of the N-O bond.
- Bond order between the (N-O) bond is 1 which means that bond length of the N-O bond is longer than that of the bond length of (N=O) bond.
