Although buying a certificate of deposit can earn your higher returns than a regular savings account, it can have the negative side effect of a. needing frequent transfers to stay active b. requiring a high initial investment c. being taxed when invested and when withdrawn d. having to be tied to a fixed rate saving account..

The correct answer is B) requiring a high initial investment.

Although buying a Certificate of Deposit can earn you higher returns than a regular savings account, it can have the negative side of effect of requiring a high initial investment.

When deciding on making a good investment move, a Certificate of Deposit is an option. This investment instrument is a savings certificate with a fixed date for renovation. It has a fixed interest rate. It can pay high return but you cannot access the money until the maturity day. Although a Certificate of Deposit gives higher interest rates to the investor that a common saving account, it has a negative: it requires a high initial amount of money to invest.

A) 1.67 grams H2CO3

Explanation:

A. This is a gram to gram conversion so first you need to find the atomic mass for 1 mole of Na2CO3 (105.988 grams) you'll then divide by how many grams you have (2.86) by 105.988 which will give you 0.02698419

0.02698419 is how many moles of Na2CO3 you have

Next you'll use the coefficients to find how many moles of H2CO3 you have and since both the coefficients are the same (1) you know you have 0.02698419 moles of H2CO3

You're then going to multiply this by the atomic mass of H2CO3 (62.024 grams) to get 1.6736674 grams of H2CO3

Now convert this number in sig figs

I'm so sorry but I don't know how to do B
