Explanation:

Low interest rates are better than high interest rates when borrowing money with a card or loan. Low-interest are beneficial for people who need to carry a balance from time to time, because less interest means less opportunity to slide into unmanageable debt.

B and D would be the lower interest rates.

Compound interest allows funds to grow at a faster rate than they would in an account with a simple interest rate. Compound interest include calculating the annual percentage yield, the annual rate of return or the annual cost of borrowing money. The cost of compound interest is not always apparent and if investments are not managed, making interest payments can cost money. Simple interest is calculated based on the principal amount and the earned interest is not compounded.

C gains less interest than A.

The higher the interest rate, the more money earned or the more money owed.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂
