Since the mole ratio is 1 to 1 for this reaction, you can just use M1V1 = M2V2 to solve, given that 1 refers to HBr and 2 refers to LiOH.

M1 = ?
V1 = 0.40 L
M2 = 0.50 M
V2 = 0.20 L

M1(0.40) = (0.50)(0.20)

Solve for M1 —> M1 = (0.50)(0.20)/0.40 = 0.25 M HBr

Charles's law is an experimental gas law that shows the relationship between the temperature of a gas and its corresponding volu
iren [92.7K]

Answer:

The correct answer is (b)

Explanation:

Charles law describes the behavior of gases when heated. Charles law states that the volume of a given mass of gas would increase as its Kelvin temperature increases provided the pressure is held constant. That is the volume of a given mass of gas is directly proportional to its Kelvin temperature at constant pressure

Use the pop-up menus to label the following statements as either True of False.
goldenfox [79]

Answer:

1 True

2. True

3. True

4. True

5. False

Explanation:

1. Hypochlorous acid (HOCl)  is a weak acid that forms when chlorine dissolves in water, and is partially dissociated, forming hypochlorite. HOCl is considered a strong oxidizing agent responsible for the killing action of germs in chlorine solutions.

2. Acetic acid is also known as ethanoic acid. It has a distinctive sour taste and pungent smell, and is generally considered a weak acid. in a concentrated form, acetic acid can be corrosive.

3/4 . Methylene chloride is an organochloride compound with the formula CH2Cl2. It is  a colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. It is normally stable, non-flammable and non-explosive when mixed with air at temperatures below 100 °C, but its vapor is flammable only when present in relatively high concentrations of about 14% to 22% in air. Research shows that it is very much possibly carcinogenic, and it has been linked to cancer of the lungs, liver, pancreas, breast cancer and salivary gland cancer in laboratory animals.

5. Laboratory and medical waste are not to be disposed in the trash with regular wastes, as they are potentially toxic. Special disposal methods and agencies exists to take away such wastes.
