What must be true for a substance to be able to dissolve in water?The solute particles must have a strong attraction for the water particles.
The solute must be able to react with water at the given temperature.
There must be enough energy to break the chemical bonds in the water molecules.
The temperature must be high enough to cause the solute to melt.

Answers

Answer 1

Answer:

In order for a solute to dissolve in a solvent, the attractive forces between solute particles and the solvent particles must be stronger than the attractive forces between solute-solute and solvent-solvent particles. This is important so that the solute will remain in solution.

Did Pb2+ react with KI? Yes or No? State the reason of your answer.

Answers

Yes, Pb2+ react with KI.

Pb2+ is lead (II) ion
KI is a compound. It is a combination of potassium (K) and iodine (I). It is called potassium iodide.

Both potassium and iodine are highly reactive elements. Thus, when they are combined with another element like Pb2+, Pb2+ reacts with KI

Answer: Yes, lead ion will react with potassium iodide.

Explanation: When lead ion reacts with KI, a bright yellow colored precipitate is formed.

The reaction of these two follows:

$Pb^(2+)(aq.)+2KI(aq.)\rightarrow PbI_2(s)+2K^+(aq.)$

Hence, $Pb^(2+)$ ion reacts with KI to yield $PbI_2$

This test is the confirmatory test for lead ion which is present in Group I.

Which step would help a student find the molecular formula of a compound from the empirical formula?Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Subtract the ratio of the actual mass of the compound to the empirical formula mass from the subscripts of the empirical formula.

Divide the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Add the ratio of the actual mass of the compound to the empirical formula mass to the subscripts of the empirical formula.

Answers

Answer : Option A) Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Explanation : To find molecular formula for a compound one needs to follow the below steps using the emphirical formula of that compound.

Step 1) Calculate the empirical formula mass of that compound

Step 2) Take the ratio of gram molecular mass by the empirical formula mass that was obtained in step 1.

Step 3) Multiply each of the subscripts within the empirical formula by the number that is calculated in step 2.

By following these easy steps one can find the molecular formula.

The step that would help a student finds the molecular formula of a compound from the empirical formula is by ‘Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.’
