Answer:
we have a certain amount of Cl2 and want to calculate how much CCl4 we need, we would use the ratio of 1 mole of CCl4 for every 2 moles of Cl2.
Step-by-step explanation:
The balanced chemical equation for the reaction of CCl4 to Cl2 is:
CCl4 → 2Cl2
From the equation, we can see that for every one molecule of CCl4, two molecules of Cl2 are produced.
This means that the molar ratio of CCl4 to Cl2 is 1:2.
In other words, if we start with one mole of CCl4, we would expect to produce two moles of Cl2. Conversely, if we have a certain amount of Cl2 and want to calculate how much CCl4 we need, we would use the ratio of 1 mole of CCl4 for every 2 moles of Cl2
