I know how to do the calculations (volume to volume, volume to mass, mass to mass), but Im not sure how to set up the equation and the question is confusing me...
<< snip >>
Can you list the calculations you know so we can see what you know?
10a) How many grams of sulphuric acid will neutralize 10.0 g of sodium hydroxide?
b)What volume of water vapour at 100C and 110kPa would also be produced?
(Almost) always you must have a balanced chemical equation in order to attempt a chemical calculation.
So what are the formulae for:
sulphuric acid
sodium hydroxide
How do those two react? What are the products of this reaction? Can you write a chemical equation for this reaction?
Next: the general approach to chemical calculations about quantities of materials is to convert all the amounts into moles, use the balanced chemical equation you worked out above, work out the unknown moles , then convert back into masses or volumes or concentrations. Getting everything into moles is central.
Next: what equations do you know that relate:
moles, masses, volumes of gases etc. (the molar equations)
for gases: pressure, volume, temperature, number of moles etc.
**The next questions have fractions, Im not sure how to do them or how the equation is balanced when fractions are there**
<< snip rest >>
Why are fractions a problem?
Go back to the balanced equation you wrote for sulphuric acid and sodium hydroxide. Now multiply all the quantities by 10. What does this mean? Well in one sense nothing has changed, because what is important in the equation is the
ratio between the quantities in the chemical equations. Similarly. If you multiply every term in the chemical equation by 1/2 or 1/3 or 1/10 all the quantities stay in the same
ratio.
