As the hydrogen in the sun decreases, helium increases. Eventually, there won't be
enough hydrogen remaining to maintain the sun's present rate of energy production.
At that point, the sun will undergo drastic changes in its size and energy output that will,
first, cook any life remaining on Earth at that time, and eventually, incinerate the Earth itself.
It decreases as the square of the distance.
It decreases.
Usually, as the angle of incidence of the sun's rays decrease (i.e. when the sun is nearer to the horizon than to the zenith) the temperature decreases.
When acids release hydrogen ions in water, the pH of the solution decreases. This is because the hydrogen ions combine with water molecules to form hydronium ions (H3O+), which make the solution more acidic.
The concentration of hydrogen ions decreases as they react with hydroxide ions from the base to form water molecules.
stuff happens Hydrogen atoms need nearly 30 kT to be torn apart This happens on the surface of the sun We can tell this from the line spectra
Yes you can make hydrogen from water through electrolysis. And also from helium (this happens in the sun)
Nuclear fusion, in which hydrogen-1 is fused into helium-4.
Our Sun is in the hydrogen fusion cycle of an average, mid-size, main sequence star. I have no idea what state YOUR Sun happens to be in.

As the angle at which the sun's rays strike the Earth's surface increases, the temperature tends to decrease. As the angle decreases, temperature tends to increase. At the same time, as the sun's angle decreases, shadows appear longer because the light is being cast at a greater angle.
Wait about 5 billion years and you will find out. Oh, you can't wait that long.... Basically, the Sun will die. As the amount of hydrogen decreases, the temperature also decreases and the Sun expands into a red giant. Slowly loosing it's outer envelope into space. After about a billion years, all that will be left is a small degenerate star, called a white dwarf.
