Answer:
2 H2 + O2 = 2 H2O
Explanation:
H2 + O2 = H2O
- Left side: 2H and 2O
- Right side: 2H and 1O
Add a coefficient of 2 to the right side
H2 + O2 = 2 H2O
- Left side is still: 2H and 2O
- Right side now has: 4H and 2O
Add a coefficient of 2 to H2 on the left side
2 H2 + O2 = 2 H2O
- Left side still has: 4H and 2O
- Right side now has: 4H and 2O
2 H2 + O2 = 2 H2O is the balanced equation.

Answer:</h3>
Wavelength-1.805 × 10^-12 m
Type of electromagnetic radiation-Gamma rays
<h3>
Explanation:</h3>
We are given the following;
Energy of a photon is 1.10 × 10^-13 Joules
We are required to calculate the wavelength's of photon
We need to know that the energy of a photon is calculated by the formula;
E = hf, but f = c/λ
Therefore;
E = hc/λ , where h is the plank's constant,6.623 × 10^-34 J-s, c is the speed of light, 2.998×10^8 m/s and λ is the wavelength.
Rearranging the formula;
λ=hc/E
Thus,
λ = (6.623 × 10^-34 J-s × 2.998×10^8 m/s) ÷ 1.10 × 10^-13 J
= 1.805 × 10^-12 m
- Therefore, the wavelength of the photon is 1.805 × 10^-12 m
- The most probable electromagnetic wave with the wavelength 1.805 × 10^-12 m is gamma rays
- This is becasue the wavelength of gamma rays is less than 1 nm or 10^-9 m
