OverLord2011 [107]

Answer:

7.54%

Explanation:

A hydrate is a salt that has molecules of water incorporated into the crystals. It is represented by the molecular formula of the salt followed by how many molecules of water it has: XY.nH₂O.

So, the mass of water in the sample will be the difference between the hydrate and the salt without water:

mass of water = 1.034 - 0.956 = 0.078 g

The mass percentage is the mass of water divided by the total mass, and then multiplied by 100%:

(0.078/1.034)x100%

7.54%

When the temperature of a sample of neon gas increases, what else increases? Distance between the atoms Kinetic energy of the at
Allushta [10]

Answer: Kinetic Energy of the atoms also increases.

Explanation: We are given that the temperature of the gas increases.

Relation between kinetic energy and temperature follows:

K.E._({avg})=\frac{3RT}{2N_A}

where, K = Average Kinetic energy

R = Gas constant

T = Temperature

N_A = Avogadro's number

As seen from the relation above, the Kinetic energy of the gas is directly proportional to the temperature, hence as the temperature increases, kinetic energy of the atom also increases.
