Answer: Option (d) is the correct answer.

Explanation:

Bases are the electron rich species which readily accept a proton. Therefore, when ammonia is classified as a base in a chemical reaction with an acid, it readily accepts a proton to give ammonium cation.

For example, the reaction of ammonia with hydrochloric acid will be as follows.

          NH_{3} + HCl \rightarrow NH^{+}_{4} + Cl^{-}

Thus, we can conclude that ammonia, NH_{3}, will accept a proton and become NH^{+}_{4}.

Calculate the hydronium ion concentration in an aqueous solution with a ph of 9.85 at 25°c.
UkoKoshka [18]

Answer:

1.41 × 10⁻¹⁰ M

Explanation:

We have a solution with a pH of 9.85 at 25 °C. We can calculate the concentration of H⁺ using the following expression.

pH = -log [H⁺]

[H⁺] = antilog -pH

[H⁺] = antilog -9.85

[H⁺] = 1.41 × 10⁻¹⁰ M

H⁺ is usually associated with water molecules forming hydronium ions.

H⁺ + H₂O → H₃O⁺

Then, the concentration of H₃O⁺ ions is 1.41 × 10⁻¹⁰ M.

The density of a pure substance is its mass per unit volume. The density of cresol has been measured to be 1024 g/L . Calculate
Ierofanga [76]

Answer: The mass of 405 ml of cresol is 415 grams

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{volume}

Given : Density of cresol = 1024 g/L

Volume of cresol = 405 ml = 0.405 L   ( 1L=1000ml)

Putting in the values we get:

1024g/L=\frac{mass}{0.405L}

mass=1024g/L\times 0.405L=415g

Thus mass of 405 ml of cresol is 415 grams

It's a weak base because weak bases don't dissociate completely. If it did, then it would be a strong base.
