A couple purchases a house for $400,000.00. They pay 20% down at closing, and take out a mortgage of $320,000.00. The mortgage company offers them a 4.80% annual rate with monthly compounding. The mortgage will require monthly payments for the next 30 years.

What will be the monthly payment on this mortgage?

Answer:

$ 1678.91

Explanation:

Given that;

Cost of purchasing a house = $400,000.00

Down payment =20%

Mortgage Value (MV) = $320,000.00

Annual rate offered by the mortgage company = 4.80% yearly i.e 0.4 per month

Duration of the Mortgage Loan (n) =  30 years which is equivalent to 360 months.

if we represent the monthly repayment with MR ,To calculate the monthly repayment MR;we have;

MV = MR × (\frac{1}{i})*[1-(\frac{1}{(1+i)^{n}} )}]

where i = 0.004 (4.8 % annually expressed as 0.48, divided by 12 monthly payments per year)

∴

320,000.00 = MR *(\frac{1}{0.004})*[1-(\frac{1}{1+0.004)^{360}}})]

320,000.00 = MR × 190.60

Monthly repayment (MR) = $ 1678.90870933

Monthly repayment (MR) ≅ $ 1678.91

At standard temperature and pressure 1 mole of any gas has a volume of 22.4 liters of gas. If the 5 grams of baking soda reacted
azamat

Answer:

1.33L of gas

Explanation:

1 mole of Baking soda (NaHCO₃) reacts with acetic acid producing 1 mole of CO₂, water and sodium acetate, thus:

NaHCO₃ + CH₃COOH → NaCH₃COO + H₂O + CO₂

5g of NaHCO₃ (Molar mass: 84g/mol) are:

5g × (1mol / 84g) = 0.0595 moles of NaHCO₃ that produce 0.0595 moles of CO₂ -Moles of gas-.

If 1 mole of gas occupies 22.4L, 0.0595 moles occupy:

0.0595 moles gas × (22.4L / mol) = <em>1.33L of gas</em>

What is the IUPAC name for the compound shown?
Anna [14]

Answer:

2,2,3-trimethyl-pentane

Explanation:

The longest chain is 5 carbons so the parent chain is a pentane. There are two methyl groups coming off the second carbon in the chain and 1 methyl group coming off the 3rd carbon in the chain. In total there are 3 methyl groups, hence we get 2,2,3-trimethyl-pentane.
