Is hydrogen burns in chlorine gas chemical or physical change?
When you combust hydrogen in air, the hydrogen will combine with oxygen to form water. Therefore, the hydrogen and oxygen are undergoing a chemical change to become bonded together producing H2O: 2H2 + O2 → 2H2O + Heat
It reacts with hydrogen to form a gas. Is it a chemical or physical property of sulfur?
it is chemical change
When sodium metal in water produces hydrogen gas is it a physical property or a chemical property?
chemical
If strontium reacts with water is it chemical or physical change?
Strontium reacts with water producing strontium hydroxide and hydrogen gas. This is a chemical change.
Is hydrogen a chemical or physical property?
Hydrogen is neither a chemical or physical property...it is a chemical element.
Is a sodium pellet placed in water catches fire and gives off hydrogen gas a physical or chemical change?
That is a chemical change. You are seeing a chemical reaction, where the sodium reacts with the water, forming sodium hydroxide and hydrogen gas.
Are compounds created through physical changes?
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.

Hydrogen is neither a chemical or physical property...it is a chemical element.

Is the gas produced when sodium mixes with water a physical change or chemical change?
It is a chemical change, as sodium cannot evaporate (or water go to water vapor) without added heat. The main gas produced in this highly exothermic chemical reaction is hydrogen, liberated from the water by the combination of a hydroxide radical (OH) with the sodium, yielding a sodium hydroxide (NaOH) solution. The heat released is typically sufficient to ignite and burn both the sodium and the released hydrogen. So pure sodium metal oddly appears to catch fire and burn when placed in water.
When sodium is put into waterit react forming sodium hydroxide and hydrogen is this physical change or chemical change?
That's most definitely a chemical change, because new forms of matter are produced. Before the reaction, you had pure sodium and water. After the reaction (which is very explosive by the way), you have sodium hydroxide and hydrogen gas.
Is physical or chemical reaction takes place when sodium hydroxide mixed with water?
It is a physical change. The sodium hydroxide dissolves, but it is still sodium hydroxide.

Is hydrogen peroxide decomposing a physical or chemical?
This is a chemical process.
