c. The theoretical yield of
is approximately 22.15 g.d. The percent yield is approximately 42.35%.
Explicación
## Step 1: The balanced chemical equation for the decomposition of hydrogen peroxide is given as:###
## Step 2:To find out how much oxygen could theoretically be produced from 25 g of
, we first need to calculate the molar mass of
. The molar mass of
is approximately 34.0147 g/mol.## Step 3:Next, we convert the given mass of
to moles using the formula:###
where
is the number of moles,
is the mass, and
is the molar mass.## Step 4:From the balanced chemical equation, we see that 2 moles of
produce 1 mole of
. Therefore, we can calculate the number of moles of
produced by multiplying the number of moles of
by 1/2.## Step 5:Finally, we convert the moles of
to grams using the molar mass of
, which is approximately 31.998 g/mol.## Step 6:To calculate the percent yield, we use the formula:###
where the actual yield is the given amount of
produced, and the theoretical yield is the amount of
that could theoretically be produced from the given amount of
.
