The following data was collected when a reaction was performed experimentally in the laboratory. Reaction Data
Reactants Products
Al(NO3)3 NaCl NaNO3 AlCl3
Starting Amount in Reaction 4 moles 9 moles ? ?

Determine the maximum amount of AlCl3 that was produced during the experiment. Explain how you determined this amount.

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

c is the answer because when something is left after something evaporates that shows the chemical change.
