2 Lots of H2 (Hydrogen Gas) + 1 lot of O2 produces 2 lots of Water (H2O) and a tiny spark of electricity (see 'How is hydrogen used to make electricity?').
2H2 + O2 ------> 2H2O is a Red-Ox reaction. The hydrogen is being oxidized and the oxygen is being reduced to produce water.
Balanced equation: 2 H2 + O2 --> 2 H2O
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
synthesis reaction
Yes you do: 2 H2(g) + O2(g) ---> 2 H2O(l) + heat
Hydrogen combines with oxygen to form water. The reaction is two molecules of hydrogen gas (H2) and one molecule of oxygen gas (O2) to form two molecules of water (H2O).
H2 +o2 --->h2o
H2 +o2 --->h2o
H2O(aq)+CO2(g)
bromine water? The reaction between hexene, bromine, and water is an addition reaction.
Chemical equations show what happens when a chemical change occurs. For example, in the combustion of Hydrogen(H2), water(H2O) is formed. The chemical equation for this reaction is: 2H2 + O2 -----> 2H2O This chemical equation shows that when H2 reacts with O2 , H2O is formed.
= H2+O2 =2H2+O2=2H2O
Hydrogen gas (H2) burns to form water (H2O). The reaction equation is as follows: 2 H2 + O2 --> 2 H2O
It is a chemical change (reaction) because the chemical composition of the products (O2 and H2) is different from the chemical composition of the water (H2O).
Balanced equation. 2H2 + O2 >> 2H2O ( now find limiting reactant ) 7 grams H2 (1 mole H2/2.016 grams) = 3.472 moles H2 60 grams O2 (1 mole O2/32 grams) = 1.875 moles O2 1.875 moles O2 (2 mole H2/1 mole O2) = 3.75 mole H2 ( checked O2, but I know H2 limits because you do not have 3.75 moles H2, so H2 drives reaction) 3.472 moles H2 (2 mole H2O/2 mole H2)(18.016 grams/1 mole H2O) = 62.552 grams H2O produced, so; 58 grams/62.552 times 100 = 92.7% yield of H2O, call it 93%
2 H2 + O2 = 2 H2O
No. It is endothermic because it absorbs energy.
The chemical equation is:2 H2 + O2 = 2 H2O
