HYDROGEN IODIDE is compound HI and is a strong acid.

CARBONIC ACID is compound H2CO3 and is a weak acid.

SULFURIC ACID is compound H2SO4 and is a strong acid.

Explanation:

Sulfuric acid is an acid that is used industrially as a corrosive, carbonic acid is generally used in soft drinks, thus giving it the low pH that these liquids confer and also gasification.

These chemical compounds are all acidic, some more complex than others, but in what they vary is that they are weak or strong, and that some have a lower pH than others.

The weaker the acid, the higher the pH, and the example in this case of this situation is HI.

The weaker the acid, the stronger this is and the lower the pH will be, therefore it will have a greater corrosive effect in some cases, and these would be sufuric acid and carbonic acid.

state the principle of separating two immiscible liquids by separating funnel. describe an activity with diagram to separate a mixture of water and kerosene oil. answer: immiscible layers separate out in layers depending on their densities in separating funne

idk what is it? is this a question that you know the answer or u dont
