Answer 1

Answer:

Hydrogen fuel is a zero emission fuel when burned with oxygen. It can be used infuel cells or internal combustion engines to power electric vehicles or electric devices. It has began to be used in commercial fuel cell vehicles such as pass enger cars, and has been used in fuel cell buses for many years. It is also used as a fuel for spacecraft propulsion.

Hydrogen is found in the first group and first period in the periodic table, i.e. it is the first elements on the periodic table, making it the lightest elements. since hydrogen gas is so light it rises in the atmosphere and is therefore rarely found in its pure form,in a flame of pure hydrogen gas, burning in air the hydrogen (H2) reacts with oxygen (O2) to form water (H2O) and releases energy.
