Alina wants to make some yummy sugar cookies today! The recipe written in her book is:
2 3/4 cup flour + 1 cup butter + 1 1/2 cup sugar+ 1 egg+1 tsp baking soda+ 1/2 tsp baking powder = 24 sugar cookies
But, Alina has the following ingredients in her kitchen: 9 cups flour, 5 cups butter, 4.5 cups sugar, 8 eggs and an excess of baking soda and powder. She is very confused and is not sure as to how many cookies can she possibly make with this list.
1. How many cookies can she make?
2. Which ingredient is her Limiting reactant?
3. Besides, baking soda and powder, how much of each reactant will be left over in Alina's kitchen?

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.
