Question

To determine how many atoms of Na would react with 1 mole of water in the given chemical reaction, you need to consider the stoichiometry. The balanced chemical equation is: 2Na + 2H2O -> 2NaOH + H2. This equation tells you that 2 moles of Na react with 2 moles of water. So, if you have 1 mole of water, you would need 1 mole of Na to react with it. Avogadro's number tells us that 1 mole of any substance contains approximately 6.022 x 10^23 entities (atoms, molecules, etc.). Therefore, the number of atoms of Na that would react with 1 mole of water is approximately 6.022 x 10^23, which corresponds to option C.

Answer 1

To determine the number of Na atoms that would react with 1 mole of water, you need to consider the stoichiometry. The balanced chemical equation shows that 2 moles of Na react with 2 moles of water. Therefore, if you have 1 mole of water, you would need 1 mole of Na to react with it. Since 1 mole of any substance contains approximately 6.022 x 10^23 entities, the number of atoms of Na that would react with 1 mole of water is approximately 6.022 x 10^23.
