The particles are no longer held together by the attractive forces keeping it a liquid (hydrogen bonds in the case of water). Enough energy has to be put into the system to break these bonds. When this happens the particles pull apart and fill the space available as a gas

Answer:
x=2.
Explanation:
Hello there!
In this case, since we have a mole ratio of moles of Cl to moles of Cu as 2.39, it is possible to write the following:
Thus, since the two possible copper chlorides are CuCl and CuCl₂, we can therefore infer that x=2 since it is close but not as close as it should to the whole number 2.
Best regards!
You want me to calculate the molality of a solution that was made by dissolving 4.9 g of H2SO4 in 50 g of water?
