Answer:

H2SO4(aq) + MgO(s) → H2O(l) + MgSO4(aq)

Explanation:

We must recall that the oxides of metals are bases. These metal oxides can react with dilute acids to yield salt and water.

Bearing that in mind, we want to obtain magnesium sulfate from a metal oxide and dilute acid.

In this case we need magnesium oxide and dilute sulphuric acid. The reaction occurs as follows;

H2SO4(aq) + MgO(s) → H2O(l) + MgSO4(aq)

Butyric acid is responsible for the odor in rancid butter. A solution of 0.25 M butyric acid has a pH of 2.71. What is the Ka fo

Snezhnost [94]

Answer:

Ka = 1.5 × 10⁻⁵

Explanation:

Butyric acid is a weak acid that ionizes according to the following equation:

CH₃-CH₂-CH₂-COOH(aq) ⇄ CH₃-CH₂-CH₂-COO⁻(aq) + H⁺(aq)

We can find the value of the acid dissociation constant (Ka) using the following expression:

$Ka=\frac{[H^{+}]^{2} }{Ca}$

where

[H⁺] is the molar concentration of H⁺

Ca is the initial molar concentration of the acid

We can find [H⁺] from the pH.

pH = -log [H⁺]

[H⁺] = antilog -pH = antilog -2.71 = 1.95 × 10⁻³ M

Then,

$Ka=\frac{(1.95 \times 10^{-3})^{2} }{0.25} =1.5 \times 10^{-5}$

Where the use of energy is concerned (in scientific sense),when is work done?

Schach [20]

Work is done only when the applied force is able to displace any object through certain distance. So, energy is concentrated on certain object that is to be displaced.
