2. it is used as a food preservative

3. It is used as an industrial source of sodium and chlorine

Uses of Sodium hydroxide:

1. It is in the laboratory as an alkali in the neutralization of acids

2. It is used in the manufacture of soap

3. It is used in the refining of petroleum

Uses of Sodium carbonate:

1. It is used in the manufacture of detergents and glass

2. It is used to soften hard water

3. it is used to standardize acids in the laboratory

Uses of Sodium sulphate

1. It is used in the manufacture of detergents and glass

2. It is used as a purgative

3. It is used to treat wood-pulp for paper making.

Uses of Potassium nitrate

1. It is used in making gunpowder

2. It is used as rocket propellant

3. It is used in making fertilizer

Uses of Potassium chlorate

1. It is used as an oxidizer

2. It is used in making explosives

3. it is used as a disinfectant

Uses of Potassium permanganate (vii)

1. It is used as an oxidizing agent

2. It is used as a disinfectant

3. It is used as an analytical reagent

Uses of Potassium chloride

1. It is used for the manufacture of fertilizer

2. It is used as an alternative salt to sodium chloride

3. It is used in medicine to treat low blood pressure

2. Potassium nitrate and potassium chloride are used in the manufacture of fertilizers.

Potassium nitrate is used in fertilizers because it provides two important plant nutrients, nitrogen and potassium to plants.

Potassium chloride (potash) is used in fertilizers because it efficiently deliver the important plant nutrient, potassium, to plants.

Iodine monochloride (ICl) has a higher boiling point than bromine (Br2) partly because iodine monochloride is a(n)

tekilochka [14]

Answer: polar molecule.

Explanation:

The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.

Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.

Bromine $(Br_2)$ is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.

Now molecules: Choose... molecules of H 2 + Choose... molecules of O 2 → Choose... molecules of H 2 O

kirill [66]

Consider this balanced chemical equation:
2 H2 + O2 → 2 H2O
We interpret this as “two molecules of hydrogen react with one molecule of oxygen to make two molecules of water.” The chemical equation is balanced as long as the coefficients are in the ratio 2:1:2. For instance, this chemical equation is also balanced:
100 H2 + 50 O2 → 100 H2O
This equation is not conventional—because convention says that we use the lowest ratio of coefficients—but it is balanced. So is this chemical equation:
5,000 H2 + 2,500 O2 → 5,000 H2O
Again, this is not conventional, but it is still balanced. Suppose we use a much larger number:
12.044 × 1023 H2 + 6.022 × 1023 O2 → 12.044 × 1023 H2O
These coefficients are also in the ratio of 2:1:2. But these numbers are related to the number of things in a mole: the first and last numbers are two times Avogadro’s number, while the second number is Avogadro’s number. That means that the first and last numbers represent 2 mol, while the middle number is just 1 mol. Well, why not just use the number of moles in balancing the chemical equation?
2 H2 + O2 → 2 H2O

Given that the molar mass of NaNO3 is 85.00 g/mol, what mass of NaNO3 is needed to make 4.50 L of a 1.50 M NaNO3 solution?

marissa [1.9K]

Mass = molarity x molar mass( NaNO₃) x volume

mass = 1.50 x 85.00 x 4.50

mass = 573.75 g of NaNO₃

hope this helps!
