2 H2 + 02 arrow 2820 there are four atoms of hydrogen h before the reaction how many atoms of hydrogen are present after the reaction 5482
The balanced equation for the reaction is:
2 H2 + O2 → 2 H2O
From the equation, we can see that for every 2 molecules of H2 reacting, we get 2 molecules of H2O.
Since there are 4 atoms of hydrogen (H) in 2 molecules of H2, we can say that there are 4 atoms of hydrogen before the reaction.
However, the given number "5482" seems unrelated to the problem. Therefore, without any additional information or context, we cannot say how many atoms of hydrogen are present after the reaction.
To determine the number of atoms of hydrogen present after the reaction, we need to understand the balanced chemical equation and the stoichiometry involved.
The given equation is: 2 H2 + O2 → 2820
From the equation, we can see that 2 moles of hydrogen (H2) react with 1 mole of oxygen (O2) to produce 2820 of something. However, the equation does not specify the unit or the substance being produced, so we cannot determine the number of hydrogen atoms based solely on this equation.
To calculate the number of hydrogen atoms before and after the reaction, we need more information.
To determine the number of atoms of hydrogen present after the reaction, we need to consider the balanced chemical equation:
2 H2 + O2 → 2 H2O
From the balanced equation, we can see that 2 molecules of H2 react to form 2 molecules of H2O.
Since each molecule of H2 contains 2 atoms of hydrogen, we can calculate the total number of atoms of hydrogen present after the reaction:
Initial number of hydrogen atoms = 4 H2 × 2 H = 8 H atoms
In the reaction, 2 molecules of H2 are consumed, resulting in the formation of 2 H2O molecules. Each H2O molecule contains 2 atoms of hydrogen.
Total number of hydrogen atoms after the reaction = 2 H2O × 2 H = 4 H atoms
