Hbr + h₂so₄ so₂ + br₂ + h₂o did h change oxidation number?

No, the oxidation state of hydrogen does not change in the given chemical reaction.

Explanation: Balancing the given chemical equation, we get:

Reactant side:

In HBr, the oxidation state of bromine is -1, so to form a neutral compound, hydrogen should have an oxidation state of +1.

In , the oxidation state of sulfate is -2, so to form a neutral atom, two hydrogen atoms having +1 oxidation state should combine with it.

Product side:

In , the oxidation state of hydroxide ion is -1, so to form a neutral water molecule, hydrogen should have an oxidation state of +1.

From above, we can say that the oxidation states of hydrogen atom did not change for the following chemical reaction.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
