Question

When hydrogen gas is burned in air it combines with carbon dioxide and water is formed.
Correct the sentence​

Answer 1

Answer:

when hydrogen gas is burned in air it combines with the oxygen present in the air to form the compound water.

Answer 2

ANSWER: When hydrogen gas is burned in the air it combines with oxygen and water is formed.

EXPLANATION:

• The gases nitrogen, oxygen, and argon make up the majority of the air that surrounds us. 20.8% of oxygen is present in the air.
• When hydrogen is burned, it combines with the oxygen already present in the atmosphere to create the compound water.
• Reaction how hydrogen and oxygen interact chemically:

2H₂ + O₂→ 2H₂O

• This type of reaction is called a combination reaction.
• This reaction is exothermic because heat is evolved along with the production of water.
• Reaction of hydrogen with carbon dioxide produce methane not water.

Therefore, it follows that hydrogen burning in air causes a chemical process that results in the production of water.
