question:Which accounts from the given list are relevant to the following transaction? The company acquired new equipment by paying 15,000 in cash.
answer:The applicable accounts are: C. cash and F. equipment The journal entry to record this transaction is as follows: Debit Equipment 15,000 Credit Cash 15,000 This entry reflects the acquisition of equipment by reducing the cash balance and increasing the equipment asset account by the same amount.
question:What is the minimum mass of water required to produce 200 g of sulfuric acid in the reaction between sulfur trioxide (SO₃) and water (H₂O), forming sulfuric acid (H₂SO₄)?
answer:To determine the minimum mass of water needed, we'll first establish the balanced chemical equation for the reaction: [ SO_3 + H_2O rightarrow H_2SO_4 ] Given: - Mass of sulfuric acid produced = 200 g - Molar mass of sulfuric acid (H₂SO₄) = 98.08 g/mol First, we calculate the moles of sulfuric acid produced: [ moles,H_2SO_4 = frac{mass,H_2SO_4}{molar,mass,H_2SO_4} = frac{200,g}{98.08,g/mol} = 2.039,moles,H_2SO_4 ] From the balanced equation, the mole ratio of sulfuric acid to water is 1:1, which means the moles of water required are also 2.039 moles. Now, let's find the mass of water needed: [ mass,H_2O = (moles,H_2O)(molar,mass,H_2O) = (2.039,moles)(18,g/mol) = 36.7,g,H_2O ] Therefore, the minimum mass of water necessary to produce 200 g of sulfuric acid is 36.7 grams.
question:Toto and Associates preferred stock is currently trading at 27.50 per share. The firm nets 25.60 after issuance costs. The stock pays an annual dividend of 3.00 per share. What is the cost of existing preferred stock and the cost of new preferred stock, respectively?
answer:For the existing preferred stock, its price is equal to the discounted present value of future dividends. Therefore, we can calculate the cost of existing preferred stock as follows: Cost of existing preferred stock = Dividend per share / Price of existing preferred stock = 3.00 / 27.50 = 10.91% For the new preferred stock, its price is lower than that of existing preferred stock because of issuance costs. Therefore, we can calculate the cost of new preferred stock as follows: Cost of new preferred stock = Dividend per share / Price of new preferred stock = 3.00 / 25.60 = 11.72% The cost of existing preferred stock is 10.91%, and the cost of new preferred stock is 11.72%.
question:How many atoms are present in 5.20 x 10^-19 g of chlorine gas?
answer:First, convert the mass of chlorine gas to moles using its molar mass: {eq}rm MM Cl_2 = 70.90 g/mol[2ex] moles = 5.20 times 10^{-19} g times dfrac{1 mol}{70.90 g} = 7.33 times 10^{-21} moles {/eq} Then, convert moles to atoms using Avogadro's number, noting that chlorine gas is diatomic: {eq}rm Avogadro's number = 6.022 times 10^{23} atoms/mol[2ex] atoms = 7.33 times 10^{-21} moles times dfrac{6.022 times 10^{23} atoms}{1 mol} times 2 = boxed{mathbf{8.82 times 10^3 atoms Cl_2}} {/eq}
