How many moles of chlorine are needed to react with 2.5 moles of sodium?
To determine the number of moles of chlorine needed to react with sodium, we need to look at the balanced chemical equation for the reaction between chlorine and sodium.
Let's assume the equation is:
2 Na + Cl2 → 2 NaCl
According to this equation, the ratio between sodium (Na) and chlorine (Cl2) is 2:1. This means that for every 2 moles of sodium, 1 mole of chlorine is needed.
In the given question, we are provided with 2.5 moles of sodium.
To calculate how many moles of chlorine are needed, we can use the ratio from the balanced equation:
(Number of moles of chlorine) = (Number of moles of sodium) / (Ratio between sodium and chlorine)
(Number of moles of chlorine) = 2.5 moles / 2
(Number of moles of chlorine) = 1.25 moles
Therefore, 1.25 moles of chlorine are needed to react with 2.5 moles of sodium.
2Na + Cl2 --> NaCl
so, 1/2 as many moles of Cl2 as Na.
