Question

In one or two sentences, explain why the combined weight of several liquids mixed in an open flask can be less than but never more than the sum of all the weights of the ingredients.(2 points)

Answer 1

I think his answer is good

Answer 2

Answer:

Liquids in a form of mixture has less weight as compared to sum of all liquid's weight due to release of gases.

The combined weights of several liquids mixed in an open flask be less than the sum of all the weights of the liquids because when the reaction occurs new products are formed and also some gases which releases in the atmosphere.

These gases also contribute in the weight of the product so when it is released the weight of the mixture of liquids are less than the sum of the weights of all liquids so we can conclude that liquids in a form of mixture has less weight as compared to sum of all liquid's weight.
