Case Development began operations in December 2016. When property is sold on an installment basis, Case recognizes installment income for financial reporting purposes in the year of the sale. For tax purposes, installment income is reported by the installment method. 2016 installment income was $320,000 and will be collected over the next three years. Scheduled collections and enacted tax rates for 2017–2019 are as follows:

On Dec 31, 2016, Riyadh Company had accounts:

2. Ending accounts receivable                                                         800,000
3. Sales discousnts                                                                          120,000
4. Sales returns and allowances                                                       280,000
5. Beginning accounts receivable                                                   750,000
6. Allowance for doubtful accounts (credit)                                     12,000            
7. The aging schedule (aging method) for the company’s accounts receivable is shown in the following table:

Requirements:

1. If the compnay’s use the percentage of net credit sales method (3%) to estimate its allowance for the doubtful accounts, answer the following two questions:

• What is the balance of the allowance for doubtful accounts on Dec 31, 2016?
• What is the bad debt expense that should be reported in the 2016 income statement?

2. If the compnay’s use the percentage of the aging method of accounts receivable to estimate its alloance for the doubtful accounts, what is the required balance for the the doubtful accounts on Dec 31, 2016?
   • What is the balance of the allowance for doubtful accounts on Dec 31, 2016?
   • What is the bad debt expense that should be reported in the 2016 income statement?

Calculate the cell potential for a reaction in a electrolytic cell with the following half-reactions if: [U 3+] = 0.10 M, [MnO4 - ] = 0.20M, [Mn2+], and [H+ ] = 0.20 M

U 3+ + 3e -> U o Ecell = - 1.642 V

MnO4 - + 8H+ + 5e- -> Mn2+ + 4H2O Ecell = +1.51 V

What is the standard voltage or cell potential of a Cr-Hg cell? (Remember to switch one-half reaction to oxidation and to balance the number of electrons--use paper.)

Cr³⁺(aq)+ 3e^- → Cr(s) E^o = -0.74 V
Hg²⁺(aq)+ 2e^- → Hg(l) E^o = +0.789 V
