How many molecules of N2 are needed to react with 30 molecules of H2 to produce Ammonia for fertilizer?
N2 + 3H2 ==> 2NH3
Look at the coefficients. It takes 1 of N2 to react with 3 H2 so it must take ????? to react with 30 H2.
To determine the number of molecules of N2 needed to react with 30 molecules of H2, we first need to understand the balanced chemical equation for the reaction.
The balanced chemical equation for the reaction between nitrogen gas (N2) and hydrogen gas (H2) to produce ammonia (NH3) is:
N2 + 3H2 -> 2NH3
From the equation, we can see that 1 mole of N2 reacts with 3 moles of H2 to produce 2 moles of NH3.
To find the number of moles of N2 needed, we need to convert the given number of H2 molecules to moles.
Since 1 mole of any substance contains 6.022 x 10^23 molecules (Avogadro's number), we can use this conversion factor to calculate the moles of H2:
30 molecules H2 x (1 mole H2 / 6.022 x 10^23 molecules H2) = (30 / 6.022 x 10^23) moles H2
Now, we can use the balanced chemical equation to determine the number of moles of N2 needed. Since the ratio of N2 to H2 is 1:3, we multiply the moles of H2 by the ratio:
(30 / 6.022 x 10^23) moles H2 x (1 mole N2 / 3 moles H2) = (30 / (6.022 x 10^23 x 3)) moles N2
Finally, we convert the obtained moles of N2 back to molecules by multiplying by Avogadro's number:
(30 / (6.022 x 10^23 x 3)) moles N2 x (6.022 x 10^23 molecules N2 / 1 mole N2) = (30 / 3) molecules N2
Therefore, the number of molecules of N2 needed to react with 30 molecules of H2 is 10 molecules of N2.
