moles and formula

?
what is the equation for atom economy
mass of desired product/mass of all products x 100
1 of 12
what is the equation for percentage yield
actual yield/theoretical yield x 100
2 of 12
what is the importance of percentage yield
tells us what percentage of our reactants have been converted to products, indicates how successful our chemical reaction has been
3 of 12
why is the percentage yield not always 100% percent
un-wanted by products - result of side reactions occuring, some of the reactants may remain unreacted, some product may be lost and the reaction may not proceed to completion as they are in equilibriu
4 of 12
what is concentration
it is the measure of how much solute is dissolved in a given volume of solvent
5 of 12
what is the equation for solution volumes
moles = concentration x volume
6 of 12
what is a concentrated solution
large amounts of solute per dm3 of solvent
7 of 12
what is a dilute solution
samll amounts of solute per dm3 of solvent
8 of 12
how do you form a salt from an alkalis
acid + base ----> salt + water
9 of 12
how do you form a salt from a metal
metal + acid ----> salt + hydrogen gas
10 of 12
how do you form a salt from a metal oxide
metal oxide + acid ----> salt + water
11 of 12
