Answer:

The presence of <em>silver nitrate impurities</em> is the most probable cause for the initial precipitate result.

Explanation:

In test for halide ions, silver nitrate AgNO_{3} is used to test for the presence of soluble halide ions. The presence of AgNO_{3} in the reaction mixture (possibly the HNO3) gave the semblance of test for chlorides, allowing for formation of precipitation in the initial experiment.

This error could have been caused by handling of reagents and used laboratory apparatus during the initial reaction.

(a) A mixture of milk and water can be separated by filtration.<br>and by which method ​
kap26 [50]

Answer:

Distillation

Explanation:

Distillation is the process of separating the components of a liquid by using the method of selective boiling and condensation.

Since the components of the liquid have different boiling points, they would evaporate at different temperatures, thus causing the separation to occur.

So, distillation can be used to separate a mixture of milk and water.

Suppose two gases in a container have a total pressure of 1.30 atm. What is the pressure of gas B if the partial pressure of gas
Korolek [52]

Answer:

P(B) = 0.45 atm

Explanation:

Given data:

Total pressure = 1.30 atm

Partial pressure of A = 0.85 atm

Pressure of B = ?

Solution:

Total pressure = P(A) + P(B)

P(B) = Total pressure -  P(A)

P(B) = 1.30 atm - 0.85 atm

P(B) = 0.45 atm
