What is the hydronium ion concentration in an aqueous hydrobromic acid solution with a pH of 4.530?
Aloiza [94]

Answer:

2.951 × 10⁻⁵ M

Explanation:

Let's consider the acid reaction of hydrobromic acid according to Brönsted-Lowry acid-base theory.

HBr(aq) + H₂O(l) ⇒ Br⁻(aq) + H₃O⁺(aq)

Given the pH = 4.530, we can calculate the concentration of the hydronium ion using the following expression.

pH = -log [H₃O⁺]

[H₃O⁺] = antilog -pH = antilog -4.530 = 2.951 × 10⁻⁵ M

Pls help! 2CO + O2 → 2CO2
jok3333 [9.3K]

The bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ

Since the chemical reaction is 2CO + O₂ → 2CO₂ and the total bond energy of the products carbon dioxide CO₂ is 1,472 kJ.

Since from the chemical reaction, we have 2 moles of CO₂ which gives 1,472 kJ and there are two carbon-oxygen, C-O bonds in CO₂, then

2 × C-O bond = 1,472 kJ

1 C-O bond = 1.472 kJ/2

C-O bond = 736 kJ

So, the bond energy of each carbon-oxygen bond in carbon dioxide is d. 736 kJ
