Which is formed by positive ions from a base and negative ions from an acid? a. Salt b. Vinegar
max2010maxim [7]

The formation of salt takes place by the sharing of positive ions from a base and negative ions from an acid.

This is based on the concept and principles of neutralization. The process of neutralization is the name of a chemical reaction between an acid and a base.

Hence, the correct option is a.

pH refers to a measure of how acidic or basic a solution is.

A pH is a measure of how basic or acidic a substance is. pH has a range of 0-14. A pH greater than 7 means the substance is basic.

A pH less than 7 means the substance is acidic. When the pH is exactly 7 that indicates that the substance is neutral.

Hence, the correct optiion is a.

The pH of a solution that has the same number of hydrogen ions as hydroxide ions is 7.

Hence, the correct option is c.

Baking soda has the greatest number of hydroxide ions.

Thus is because of the pH is 9. So, it will be more basic.

Hence, the correct option is a.

Hydrochloric acid will be least likely to completely dissolve in water.

Hence, the correct option is a.

Antacid is taken to get relieve from heartburn describes that the antacid is acidic and will raise the pH of the esophagus.

Hence, the correct option is c.

Answer:

The answer to your question is:  ΔH = -283 kJ/mol, first option

Explanation:

Reaction

                CO  +  O₂     ⇒     CO₂

ΔH = ∑H products - ∑H products

ΔH = -393.5 - (-110.5 + 0)

ΔH = -393.5 + 110.5

ΔH = -283 kJ/mol

Why do group 1 cations form precipitates when mixed with hcl?
Xelga [282]
Both of you are overlooking a pretty big component of the question...the Group I cation isn't being dissociated into water. We're testing the solubility of the cation when mixed with HCl. And this IS a legitimate question, seeing as our lab manual is the one asking. 

<span>By the way, the answer you're looking for is "Because Group I cations have insoluble chlorides". </span>

<span>"In order...to distinguish cation Group I, one adds HCl to a sample. If a Group I cation is present in the sample, a precipitate will form." </span>
