When hydrogen is fused in the suns core Helium is produced.

When two hydrogen atoms fuse together, they can form helium, which is a new element. This fusion process releases a large amount of energy and is the process that powers the sun and other stars.
The reaction of sodium metal with water to produce hydrogen gas is a chemical property. This is because a new substance (hydrogen gas) is formed as a result of a chemical reaction between sodium and water.
When sodium is mixed with water, it produces sodium hydroxide (NaOH) and hydrogen gas (H2). This reaction is highly exothermic and produces enough heat to ignite the hydrogen gas.
Yes, the reaction between hydrochloric acid and magnesium to produce hydrogen gas is a chemical change. This is because chemical bonds are broken and new bonds are formed, leading to the formation of a new substance (hydrogen gas) with different properties than the original reactants.
This is a chemical change. When sodium reacts with water, it undergoes a chemical reaction to produce hydrogen gas and sodium hydroxide. The formation of new substances (sodium hydroxide) and the evolution of gas (hydrogen) indicate a chemical change rather than a physical one.
A single displacement reaction is a type of chemical reaction where a free element replaces another element in a compound. This occurs when a more reactive element displaces a less reactive element in a compound, forming a new compound and releasing the displaced element.
