Answer:

C. Precipitation of white bismuth hydroxide.

Explanation:

When aqueous ammonia is added to a solution that has Bi3+ and CU2+ cations, what we would have as a chemical result is the precipitation of white Bismuth hydroxide.

The chemical reaction for this can be written as,

Bi3+ + 2NH3 + 3H2O ⇌ Bi(OH)3(s) + 3NH4

Thank you!

The volume of a sample of <img src="https://tex.z-dn.net/?f=P_b" id="TexFormula1" title="P_b" alt="P_b" align="absmiddle" class=
murzikaleks [220]

Answer : The mass of sample is, 267.5 grams.

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

Density=\frac{Mass}{Volume}

Given:

Volume of Pb = 23.57cm^3

Density of Pb = 11.35g/cm^3

Now put all the given values in the above formula, we get the mass of Pb.

11.35g/cm^3=\frac{Mass}{23.57cm^3}

Mass=267.5195g=267.5g

Therefore, the mass of sample is, 267.5 grams.

List the following molecules in order of increasing boiling point: Br2, Cl2, F2, I2.
Andrej [43]

Answer:

1. None of these have hydrogen bonding.

2. None of these have dipoles.

3. Bigger molecules will have stronger London dispersion forces. So I2 has the strongest forces,

and F2 will have the weakest. Correspondingly, I2 will have the highest boiling point and F2 will have the lowest boiling point.

Answer: F2, Cl2, Br2, I2
