You don't. You can extract it from water though.
Ask your self
you extract them by drilling wells
we extract it from fossil fuelsHydrogen is obtained by the electrolysis of water.
Answering "Experiment on the effect of the PH of enzymatic reaction using hydrogen peroxide and extract of spinach leaf?"
You extract the hydrogen pronuerons after you subtract the number of posotive electrons.
yep

you can not "create" hydrogen. you can release it from chemical bonds such as from water. to extract hydrogen from water you need to pass an electrical current through the water and capture the gas which comes out, however this is hydrogen and oxygen.
Hydrogen gas only exists in the atmosphere in trace amount. The hydrogen in water vapor, which is more abundant, is chemically bound to the oxygen in the molecule and thus require large amounts of energy to extract.
covalently bonding it to another hydrogen ion
actually you can still extract lead from lead oxide, but you need to do this experiment with carbon or other reducing agent e.g. hydrogen and with a high temperature Celsius. But the reason that you can extract the mercury from the mercury oxides exactly is the higher reactivity of the lead. higher the reactivity means more difficult to extract the metals from the ore. so it is possible for lead to extract it from the lead oxide
