Explanation:
To balance the hydrogen atoms, we check the number of hydrogen on the left side, this is equal to the 10 hydrogen atoms we have in the alkanol.
Now, on the right hand side, we can see we only have two hydrogen atoms in the water molecule. Now, to make equal the number of hydrogen atoms on both sides, we simply multiply the number of hydrogen there by 5 to make it 10 too
The energy at n level of hydrogen atom energy level =13.6/n^2
substiture the respective n values in the equation above and find the difference in the energy levels

Explanation: nitrogen is around 70% of the air hope this helps god bless
Answer:
As the axial tilt increases, then the seasonal contrast increases so that winters are colder and summers are warmer in both hemispheres.
