denis-greek [22]

Answer:

<em>The elements of Group VIIA (new Group 17 – fluorine, chlorine, bromine, iodine, and astatine) are called the halogens (tan column). The term “halogen” means “salt-former” because these elements will readily react with alkali metal and alkaline earth metals to form halide salts</em>

Calculate the amount of heat required for the evaporation of 105.0 g of water at 100.0 c
son4ous [18]
To determine the amount of heat needed to evaporate a certain amount of water at its boiling point, we use the equation,

                  H = m(Hv)

where H is the heat, m is the mass (in grams), and Hv is the latent heat of vaporization. Substituting the known values,

                 H = (105 g)(540 cal/g)

                  H = 56700 cal

                H = 56.7 kcal

Answer: 56.7 kcal
