Explanation:

In liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.

So, when at 298 K and 1 atm Br_{2} exists in liquid state and Cl_{2} exists as a gas then it means there occurs strong force of attraction between the molecules of Br_{2} due to which it exists in liquid form.

Thus, we can conclude that at 298 K and 1 atm, bromine is a liquid with a high vapor pressure, whereas chlorine is a gas. This provides evidence that, under these conditions, the forces among Br_2 molecules are greater than those among Cl_2 molecules.

A reaction produces 92.50 g FeSO4. How many grams of CuSO4 are necessary for this to occur?
xxMikexx [17]

Fe+CuSO4⟶Cu+FeSO4

Given that  

FeSO4 = 92.50 g  

Number of moles = amount in  g / molar mass

=92.50 g / 151.908 g/mol

=0.609 moles FeSO4

Now calculate the moles of CuSO4 as follows:

0.609 moles FeSO4 * 1 mole CuSO4 /1 mole FeSO4

= 0.609 moles CuSO4

Amount in g = number of moles * molar mass

= 0.609 moles CuSO4 * 159.609 g/mol

= 97.19 g CuSO4
