Chapter 12: Atom Economy and Percentage Yield

Industrial processes

________ should have as high a percentage yield as possible to reduce waste and reduce costs.

Raw materials

________ are expensive to remove and dispose of responsibly.

Percentage yield

________ is always somewhere between 0 and 100 %.

mass of product actually made (g)

Percentage yield =/maximum theoretical mass of product x 100.

For example, in the Haber process at the same time as the reaction N2 + 3H2

2NH3 is taking place, the reverse reaction is also happening

reduce waste and reduce costs.

Industrial processes should have as high a percentage yield as possible to _________

dispose of responsibly.

Raw materials are expensive to remove and __________

0 and 100 %.

Percentage yield is always somewhere between_______

For example, in the Haber process at the same time as the reaction N2 + 3H2

2NH3 is taking place, the reverse reaction is also happening

When you filter a liquid to

______remove solid particles, you nearly always lose a bit of liquid

Not all reactants

________react to make a product

Yields are always

_____less than 100%

HIgh atom economy is

a good thing

Atom economy is

________never 10%

Atom economy equation

Relative formula mass of desired products / relative formula mass of all reactants x 100
