10. How many moles of CuCl, are in 150 L of a 2.33 M Cuci, solution?

349.5 moles

Explanation:

(I am assuming that there is a typo at the end, where Cuci solution = CuCl solution)

The formula for molarity is:

Molarity = moles in solution / volume of solution

Here, we are given both the Molarity and the volume. So we can plug it into the equation above and get:

2.33 = moles / 150

Now we solve for the moles by doing:

moles = 2.33 * 150

This gives us the answer of 349.5 moles.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

by cartels in other countries, shipped by air, mail, or land. i cant really see your answer choices : /
