Answer:
The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.
Bases- soap, baking soda
Acids- oranges,lemons
idk
The balanced chemical reaction would be expressed as follows:
2Na + Cl2 = 2NaCl
We are given the amount of sodium metal to be used reaction. This would be the starting value for the calculations. We do as follows:
6.25 g ( 1 mol / 22.99 g ) ( 1 mol Cl2 / 2 mol Na ) ( 22.4 L / 1 mol ) = 3.045 L Cl2 needed
Hope this answers the question.
