Balanced equation first.
2H2 + O2 --> 2H2O
Get moles products.
4 grams H2 (1 mole H2/2.016 grams) = 1.984 moles H2
64 grams O2 (1 mole O2/32 grams) = 2.000 moles O2
I suspect hydrogen gas of limiting and driving the reaction.
1.984 moles H2 (1 mole O2/2 moles H2) = 0.992 moles O2 ( you have more than this in equation )
2.000 moles O2 (2 mole H2/1 mole O2) = 4.000 moles H2 ( you do not have this much and H2 will drive this reaction )
1.984 moles H2 (2 moles H2O/2 moles H2)(18.016 grams/1 mole H2O)
= 36 grams water produced

How many elements are combined together in water?
Two elements, namely hydrogen and oxygen
What two elements when combined forms water?
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
When combined in a ratio with hydrogen the element makes water?
Oxygen. Hydrogen and oxygen bond in a ratio of 2 hydrogen atoms to one oxygen atom to form water, represented by the chemical formula H2O.
Can carbon and oxygen form into water?
No. Water is a compound of oxygen and hydrogen. Carbon and oxygen will combined to form carbon dioxide or carbon monoxide.
Which element is an explosive gas but when combined with oxygen in a certain way makes water?
Hydrogen
How many elements are combined together in water?
Two elements, namely hydrogen and oxygen
When combined with oxygen this element makes a compound essential for life?
oxygen and hydrogen together they make H2o (WATER DUMBA**)
What is the chemical make up of water?
Pure water contains 2 hydrogen atoms to 1 oxygen atom ratio and combined with together as H2O.
When hydrogen and oxygen combined to form water what is water?
H2o
Which is combined with hydrogen and oxygen?
Water? Well, water is H20.
What two elements when combined forms water?
The elements are: two hydrogen atoms and one oxygen atom. Combined they form water (H2O).
Why doesn't water have carbon?
Water doesn't have carbon because water is H2O, which is one hydrogen and two oxygen molecules combined together.
Why doesn't water formed by hydrogen and oxygen combust?
Because the hydrogen and oxygen are already chemically combined.
What is a sentence using the word hydrogen?
Hydrogen and oxygen combined with a catalyst create water.
Is hydrogen gas just hydrogen combined with oxygen?
No, Hydrogen gas is the diatomic element H, so it appears in nature as H2. The most common form of Hydrogen combined with Oxygen is H2O, or water.
Is energy in water from hydrogen molecules?
No. The hydrogen and oxygen in water are combined into a single substance; it does not get one property from hydrogen or another from oxygen but rather has its own unique set of properties based on how they are combined. It is unclear what "energy" you are referring to.
Most of the hydrogen in the Earth's atmosphere is combined with oxygen as water What might you conclude by that fact?
That oxygen and hydrogen are highly reactive.
