Water is formed.

When hydrogen and oxygen gases are mixed, nothing happens, until a flame is put into the mixture. Whereupon there is a 'pop' and water is formed.

Here is the BALANCED reaction eq'n

2H2(g) + O(g) = 2H2O(l)

The 'pop' test is a classic lab. test for hydrogen .

If the gases are mixed in large quantities, then the 'pop' becomes an explosion.

Fill two balloons , one with hydrogen and the other with helium. With a piece of string allow then to float in the air/room.

Put a lighted taper to the helium filled balloon. It will just pop and fall to the ground.

Put a lighted taper to the hydrogen filled balloon. It will pop with a flash of flame and a loud bang.

If you burn 24.2 of hydrogen and produce 216 of water how much oxygen reacted?

To determine the amount of oxygen that reacted when burning hydrogen, we can use the balanced chemical equation for the combustion of hydrogen: 2 H₂ + O₂ → 2 H₂O. From the equation, 2 moles of hydrogen produce 2 moles of water, meaning 1 mole of hydrogen produces 1 mole of water. Given that 24.2 grams of hydrogen (approximately 12.1 moles) produce 216 grams of water (approximately 12 moles), we can see that 12 moles of water would require 6 moles of oxygen, which corresponds to about 192 grams of oxygen. Thus, approximately 192 grams of oxygen reacted.
