A 6.0 M HCl solution is available. What volume is needed to make 6.00 L of 1.00 M<br> solution?
Ket [755]

Answer:

The volume of the stock solution needed is 1L

Explanation:

Step 1:

Data obtained from the question. This include the following:

Concentration of stock solution (C1) = 6M

Volume of stock solution needed (V1) =?

Concentration of diluted solution (C2) = 1M

Volume of diluted solution (V2) = 6L

Step 2:

Determination of the volume of the stock solution needed.

With the dilution formula C1V1 = C2V2, the volume of the stock solution needed can be obtained as follow:

C1V1 = C2V2

6 x V1 = 1 x 6

Divide both side by 6

V1 = 6/6

V1 = 1L

Therefore, the volume of the stock solution needed is 1L

based on their locations on the periodic table which best compares the properties of the metalliods arsenic (As) and antimony (S
Sliva [168]

In order to compare the two elements, one must take note of

its placement in the periodic table. As you go down a group in the periodic

table, the metallic property increases. Thus in the problem, Antimony has a

more metallic behavior than Arsenic so that already crosses out statement A and

B from the choices since it is untrue. The number of electron shells meanwhile

decreases as you go down the group. Therefore the answer would be Arsenic has a

more nonmetallic behavior than antimony because arsenic’s atoms have fewer

electron shells.
