Answer:

a) Mg and S = atoms

b) H2   SO3 = molecules

c) HBr =molecule

Explanation:

Step 1: Data given

Atoms = An atom is the smallest constituent unit of ordinary matter that constitutes a chemical element. We can find them on the periodic table.

Molecules = A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

a. Mg S  = Magnesium and sulfur both are atoms, we both can find them on the periodic table

b. H2 SO3  =  H2 is a molecule that contains 2 hydrogen atoms

SO3 is a molecule that contains 1 sulfur atoms and 3 oxygen atoms

c. HBr = HBr is a molecule that contains 1 hydrogen and 1 bromine atom

the actual yield of a product in a reaction was measured as 2.80 g. if the theoretical yield of the product for the reaction is
olga_2 [115]

The percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.

<h3>How to calculate percentage yield?</h3>

The percentage yield of a substance can be calculated by dividing the difference between the actual and theoretical yield by the actual yield, then multiplied by 100.

Percentage yield = (theoretical yield - actual yield)/actual yield × 100

According to this question, the actual yield of a product in a reaction was measured as 2.80 and the theoretical yield of the product for the reaction is 3.12 g.

Percent yield = (3.12g - 2.80g)/2.80 × 100

Percent yield = 11.43%.

Therefore, percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.
