Quantative Chemistry Flashcards
1
Q
Chemists use quantitative analysis to determine what?
A
the formulae of compounds and the equations for reactions.
2
Q
The law of conservation of mass states that
A
no atoms are lost or made during a chemical reaction so the mass of the products equals the mass of the reactants.
3
Q
The law of conservation means that chemical reactions can
A
can be represented by symbol equations which are balanced in terms of the numbers of atoms of each element involved on both sides of the equation.
4
Q
Chemical measurements
Whenever a measurement is made there is always some uncertainty about the result obtained
A
5
Q
Many chemical reactions take place in?
A
Solutions
6
Q
The concentration of a solution can be measured in ?
A
Mass per given volume of solution, eg grams per dm3 OR (g/dm3)
