Question
Copper oxide reacts with hydrogen to produce copper. The equation for the reaction is: CuO+H_(2)arrow Cu+H_(2)O Calculate the percentage atom economy for obtaining copper from this reaction. Use the equation: Percentage atom economy=(A_(r) of Cu)/(M_(r) of H_(2)+M_(r) of CuO)times 100 Relative atomic mass (A_(r)) Cu=63.5 Relative formula masses (M_(t)) H2=2 H_(2)=2 CuO=79.5 [2 mar

Substitute the gland quantities values in the formula to calculate the percentage atom economy, and as a result, it will be approximately
.
Explanation
## Step 1:Given that the relative atomic mass (
) of Copper (
) is
, and the relative formula masses (
) of
and
are
and
respectively.## Step 2:To calculate the percentage atom economy for obtaining copper from the given reaction, we'll plug the given quantities into the stated percentage atom economy equation.## Step 3:Substitute the given values (
of
), (
of
and
of
) into the percentage atom economy formula.### The percentage atom economy formula is: ###
