If you reacted 93.7 grams of iron with excess copper sulfate solution, what mass of copper would you expect to make? you may nee
Mariana [72]

Answer is although the question should have 3 significant figures.

<h3>What is significant figures?</h3>
  • Chemical equation

Fe + CuSO4 --> Cu + FeSO4

It is already balanced

  • Molar ratios

1 mol Fe : 1 mol CuSO4 : 1 mol Cu : 1 mol FeSO4

  • atomic masses of Fe and Cu

Fe: 55.8 g/mol

Cu: 63.5 g/mol

  • number of moles of Fe

number of moles = mass in grams / atomic mass = 93.7 g / 55.8 g/mol = 1.679 mol

  • number of moles of Cu:

1 mol Fe / 1 mol Cu => 1.679 mol Fe / 1.679 mole Cu

  • mass of Cu in 1.679 moles Cu

mass = atomic mass * number of atoms = 63.5 g/mol * 1.679 moles = 106.6 g = 107 rounded to 3 significant figures.

You have decided to bake a cake. You mix all of your ingredients together to make a delicious chocolate cake. Then, you bake you
Lapatulllka [165]

Answer:

A gas is evolved

The ingredients can not be recovered

Explanation:

A chemical change is one in which a new substance is formed and it is not easily reversible.

One major ingredient used in cake baking is the baking powder or baking soda.

Baking a cake can be viewed as a chemical change. This is because, when the baking powder or soda is added in the presence of yeast, carbon dioxide gas is evolved as tiny bubbles of gas which makes the cake light and fluffy. Heat is equally given off in the process. The baking powder and other cake ingredients can not be recovered, hence, we can conclusively assert that a chemical change has taken place.
