Excited mercury atoms emit light strongly at a wavelength of 428 nm. a. Calculate the energy of a photon of this radiation

Write the predicted electron configuration (short version using the noblegas core) for the following atoms  Pt Leave 1 space between each term. For example Nitrogen would be entered: [He] 2s2 2p3

Write the expected short electron configuration for As. Leave 1 space in between each term. For example: nitrogen would be [He] 2s2 2p3

A 35.0 g sample of nickel metal is heated to 100.°C and dropped into 100.0 g of water, initially at 22.0°C. Assuming that all of the heat lost by the nickel is absorbed by the water, calculate the final temperature of the nickel and the water. The specific heat of nickel is 0.444J/g°C)
