If you have an aqueous solution that contains 1.5 moles of HCl, the number of moles of ions in the solution is 3.0 moles.
<h2>Further Explanation
</h2><h3>Strong acids </h3>
- Strong acids are types of acids that undergo complete dissociation to form ions when dissolved in water.
- Examples of such acids are, HCl, H2SO4 and HNO3
- Dissociation of HCl
HCl + H₂O ⇔ H₃O⁺ + OH⁻
<h3>Weak acids </h3>
- Weak acids are types of acids that undergo incomplete dissociation to form ions when dissolved in water.
- Examples of such acids are acetic acids and formic acids.
- Dissociation of acetic acid
H₃COOH ⇔ CH₃COO⁻ + H⁺; CH₃COO⁻ is a conjugate base of acetic acid.
<h3>In this case;</h3>
- HCl which is a strong acid that ionizes completely according to the equation;
HCl + H₂O ⇔ H₃O⁺ + OH⁻
- From the equation, 1 mole of HCl produces 1 mole of H₃O⁺ ions and 1 mole of OH⁻ ions.
Therefore;
1.5 moles of HCl will produce;
= 1.5 moles of H₃O⁺ ions and 1.5 moles of OH⁻ ions.
This gives a total number ions of;
= 1.5 + 1.5
= 3 moles of ions

Answer:
A. Because they are compounds, they cannot be pure substances.
Explanation:
The false statement from the given choices is that because they are compounds they cannot be pure substances. In fact, because they are compounds they are pure substances.
Pure substances are made up of elements and compounds and they have the following properties:
- All parts are the same throughout
- Composition is definite
- They cannot easily be separated or broken
- Separation by physical method is not easy
- They have unique sets of physical and chemical properties.
Answer: D. Mutation in coding sequences are more likely to be deleterious to the organism than mutations in noncoding sequences.
Explanation: It was not likely to be that the coding sequences are replicated more often. The only possible explanation is that the mutations in coding is more likely to be deleterious to the organism than mutations because it is in a non coding sequence.
Answer:
D
Explanation:
because bio means life and biology would be the study of life.

Explanation:
Carbon monoxide is toxic because it can successfully competes with oxygen for hemoglobin (Hb) sites according to the following equilibrium:
Hb(O₂)₄(aq) + 4CO(g) ⇄ Hb(CO)₄(aq) + 4O₂(g)
Based on LeChatelier’s Principle, CO poisoning can be reversed by applying O₂(g) to victim. This addition of O₂(g) increases system concentration of O₂(g) in the equilibrium reaction thereby overloading the product side of the equilibrium forcing it to shift to the left, decomposing the carboxyhemoglobin (Hb(CO)₄) and releasing the CO(g) and combining with O₂(g) to form more Hb(O₂)₄.
