Answer:

Option B. 450mL

Explanation:

To obtain the volume of water that must be added, we need to First find the volume of the diluted solution.

C1 (concentration of the stock solution) = 8M

V1 (volume of the stock solution) = 150mL

C2 (concentration of the diluted solution) = 2M

V2 (volume of the diluted solution) =?

Using the dilution formula C1V1 = C2V2, we can obtain the volume of the diluted solution as follow:

C1V1 = C2V2

8 x 150 = 2 x V2

Divide both side by 2

V2 = (8 x 150)/2

V2 = 600mL

The volume of water added is simply the difference between the volume of the diluted solution and that of the stock solution. This is illustrated below

Volume of water added = V2 - V1 = 600 - 150 = 450mL

Which is warmer 10c or 30f
OleMash [197]

Answer:

your answer is 30f

Explanation:

The coldest possible temperature, or absolute zero, is -273.15 degrees Celsius, or 0 degrees Kelvin. So, 10 degrees Celsius (and this shouldn't be taken too literally) is in fact only about 1.8 per cent warmer than 5 degrees, and 30 degrees is only about 5.2 per cent warmer than 15 degrees.

Which two reactants make Calcium carbonate?
Norma-Jean [14]

Impossible to form from given reactants

Explanation:

Only sodium has carbonate ion here .so only possible way to displace carbonate is to use potassium

When sodium carbonate and Potassium iodide react with each other double displacement reaction occurs

As potassium is powerful than sodium it displaces sodium to form potassium carbonate .

Then you have to use water and then you can use calcium suppliment .
