Assignment Help Chemistry
Reference no: EM131824147

Question 1: As each electron is removed, one at a time, from an atom of aluminum, more ionization energy is required. Between which two successive ionization energies would you expect the greatest difference (largest change in value)? Explain your answer in terms of attraction, repulsion, and electron arrangement.

Question 2: During a lab, you heat 1.04 g of a NiSO4 hydrate over a Bunsen burner. After heating, the final mass of the dehydrated compound is 0.61 g. Determine the formula of the hydrate and also give the full name of the hydrate. Please show all your work for the calculations.

Question 3: Identify the type of bonding, molecular geometry (shape), and intermolecular forces experienced by the compounds HF and HBr. Which substance would experience a stronger attraction between its molecules, and why?

Question 4: Consider the compound FePO4 and answer the following questions:

a. What is the name of this compound?

b. What is the molar mass of this compound? Explain how you calculated this value.

Question 5: The trend for ionization energy is a general increase from left to right across a period. However, beryllium (Be) is found to have a higher first ionization energy value than boron (B). Explain this exception to the general trend in terms of electron arrangements and attraction/repulsion.

Question 6: What is the name of the compound NiSO4 • 5H2O?
