Answer:
Tetracycline and antacid should not be given together.
Explanation:
In the given order, tetracycline and antacid are given together. The antacid is in the aspirin. The tetracycline and antacid should not be used together because the presence of antacid will suppress the effectiveness of the tetracycline. This is because antacid contains chemical compounds such as sodium bicarbonate which can interact with the tetracycline.

When the cool and hot zones of a non luminous flame’s air
control valve is closed, the gas in which will be in placed as first and as it
encounters air as it was in the mouth of the burner, there will be a presence
of incomplete mixing, causing a combustion which would be incomplete and will
also lead to a process that can’t be controlled, resulting to flame that is
cool.
Hello!
When aqueous solutions of Li₂SO₄ and NaI are mixed the following reaction occurs:
Li₂SO₄(aq) + 2NaI(aq) → 2LiI(aq) + Na₂SO₄(aq)
The compounds produced from this reaction are all soluble, so no precipitate is formed. We know that those compounds (LiI and Na₂SO₄) are soluble because of the solubility rules which states that salts from Group I elements (Li⁺, Na⁺) are soluble.
Have a nice day!
Answer:
Yes, a precipitate of PbS forms
Explanation:
The equation of the reaction is given as:
Pb(NO₃)₂ + Na₂S → PbS + 2NaNO₃
The lead sulfide forms a precipitate in the aqeous solution.
Precipitation is a form of reaction in which ions combines to form a solid precipiate. Most double displacement reactions in which ionic compounds are the reactants results in formation of a precipitate as the product.
There are rules of solubility which guides a reaction that would lead to the formation of a precipitate. The mos applicable of the rules to the reaction stated above is that "carbonates, phosphates, sulfides, oxides and hydroxides are insolube". The sulfide of lead formed in the product is therefore insoluble.
