Why is oxygen needed for a seed to germinate?
The seed will need to respire aerobically (glucose + oxygen= energy + CO2 + Water) in order to release the energy needed to grow.
What else is needed for iron to go rusty?

Why is water formed when you mix hydrogen and oxygen gases?
Water is H2O. 2 hydrogen atoms and 1 oxygen atom. Water is not formed when you mix hydrogen and oxygen. An explosive mixture of hydrogen and oxygen is formed. When you burn hydrogen in oxygen, the resulting compound is water. When you boil water the result is steam, or water vapor. Boiling does NOT separate the hydrogen and oxygen. An electrical current is needed to separate the hydrogen and oxygen. CAUTION: Do NOT put salt in the water to speed up the electrolysis of water. It changes the products. instead of hydrogen and oxygen, you get hydrogen, chlorine (gas), and sodium hydroxide. The last two are very poisonous.
How many moles of oxygen gas are needed to make 4 moles of water?
4 moles of oxygen atoms are present in 4 moles of H2O
How many liters of water are needed to react with 2L of oxygen to make water?

What are the substances needed for photosynthesis and what substances are produced?
CO2 and water is needed. Oxygen and glucose are produced
What will rust?
Both water and oxygen are needed for rusting to occur.Iron and steel rust when they come into contact with water and oxygen. Both are present in the air.
