Explanation:
As the given reaction equation is as follows.
Hence, expression for of this reaction is as follows.
Now, putting the given values into the above expression as follows.
=
=
Thus, we can conclude that the value of is .
Answer:
Visible light contains all the colors from violet to red. An object gets its color when electrons absorb energy from the light and become “excited” (raised to a state of increased energy). The excited electrons absorb certain wavelengths of light.
The Sun emits light of every possible frequency at once, including at frequencies too high or too low for us to see. But the Sun's highest intensity radiation aligns approximately with our visible range – red through blue. That's no coincidence – like all animals on Earth, we have evolved to make best use of the light available.

Answer:
CH₄ + 2O₂ → 2H₂O + CO₂
Explanation:
Chemical equation:
CH₄ + O₂ → H₂O + CO₂
Balanced chemical equation:
CH₄ + 2O₂ → 2H₂O + CO₂
Option d is correct option.
1st step:
CH₄ + O₂ → H₂O + CO₂
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 2
O = 2 O = 3
Step 2:
CH₄ + O₂ → 2H₂O + CO₂
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 4
O = 2 O = 4
Step 3:
CH₄ + 2O₂ → 2H₂O + CO₂
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 4
O = 4 O = 4
