How many grams of aluminium chloride are produced when 123.2g of chlorine react with aluminium

Answers

Answer:

Mass = 154.67 g

Explanation:

Given data:

Mass of aluminum chloride produced = ?

Mass of chlorine = 123.2 g

Solution:

Chemical equation:

2Al + 3Cl₂  →   2AlCl₃

Number of moles of chlorine:

Number of moles = mass/molar mass

Number of moles = 123.2 g/ 71 g/mol

Number of moles =1.74 mol

Now we will compare the moles of aluminum chloride and chlorine.

                          Cl₂              :              AlCl₃

                            3               :                 2

                           1.74            :          2/3×1.74 = 1.16 mol

Mass of AlCl₃:

Mass = number of moles × molar mass

Mass =  1.16 mol × 133.34 g/mol

Mass = 154.67 g

Brian is making a cake for his friend's birthday. He combines the ingredients for the cake and then pours the batter into two pans and bakes them for 45 minutes in the oven. While the pans are in the oven, he combines butter, sugar, and milk and mixes them together to make the icing. What type of changes created the cake and the icing?

A. Both the icing and the cake are formed by physical changes.
B. Both the icing and the cake are formed by chemical changes.
C. The icing is formed by a chemical change and the cake is formed by a physical change.
D. The cake is formed by a chemical change and the icing is formed by a physical change.

Answers

Answer:

it’s D.The cake is formed by a chemical change and the icing is formed by a physical change

Explanation:

It’s because when the cake was baking there was nothing physical about it so it was a chemical change the icing is formed by a physical change because all you did was mix three ingredients together

The type of changes that created the cake and the icing is;

Option D; The cake is formed by a chemical change and the icing is formed by a physical change.

 

This is about understanding type of changes in chemistry.

Physical change is defined as a change that affects the form of a compound or element but it doesn't affect its' chemical composition.Meanwhile, chemical change is defined as a change that affects the composition of a compound and a new substance is formed.

Now, for brian's cake he has combined raw ingredients into two pans and bakes the cake. For the cake to be baked, it means the ingredients mixed have changed from liquid to solid and also a new substance has been formed. Thus, we can say that the cake was formed from chemical change.

Meanwhile, the icing was formed by physical change because it did not undergo any chemical process and no new substance was formed as only butter, sugar and milk were mixed together.
