you need to make 1.5L of 1.0M HCl from a stock solution of 12.0M HCl. How many L of the stock solution do you need?

Answers

Answer 1
Answer:

Answer:

125 ml of HCl

Explanation:

The molarity of the stock solution to determine how many milliliters would contain 1.5 moles of HCl. Since a concentration of 12.0 mol/L means that you get 12.0 moles of hydrochloric acid per liter of solution,  

Concentration of required HCl (C1)  = 1.0M

Volume of required HCL (V1)  = 1500 ml

Concentration of stock HCl (C2)  = 12M

Volume of stock  HCL (V2)   = ?

C1V1 = C2V2

V2 = C1V1/C2 = 1*1500/12 = 125 ml

2. Name three factors that influence the rate at which a solute dissolves in a solvent?

Answers

Answer:

1. Temperature

2. Surface area

3. Catalyst

Explanation:

Answer:

Heat, molecular size, and surface area

Explanation:

Heat: higher temperatures are directly correlated to higher kinetic energy. With more kinetic energy, the solute molecules move faster and the bonds are more likely to break.

Molecule size: usually at the same temperature and pressure, the solute with smaller molecular size dissolves faster. A large molecule usually has a heavier weight and size, which makes it more difficult for the solvent to surround it and help break its bonds.

Surface area: increasing surface area generally increases the solubility rate. This is because with a higher area, more molecules are exposed to the solvent, so their bonds are more likely to break.

The concentration (M) of a methanol solution produced when 0.400 L of a 2.00 M solution was diluted to 0.800 L is __________ M.

Answers

Answer: 1.00 M

Explanation: The problem can be solved using the formula of dilution which is the product of Molarity and volume M1V1= M2V2.

Derive for M2, so the formula will be M2 = M1V1 / M2

M2 = 2.00 M ( 0.400 L ) / 0.800 L

= 1.00 M

Answer:

1.00 M

What was helium used for in the past?

Answers

Helium used to be used in hot air balloons.  Then, when the Hindenburg exploded, annexed file, they realized that hydrogen was not only lighter, but it also was less flammable.  

Hot air balloons. They have a little hot plate/fire or whatever and they used, and that made the helium rise, thus rising the balloon.
