A) suggest two reasons why not all points lie on the line of best fit.
1.
2.

b) From graph, deduce the speed of reaction when the concentration of sodium thiosulfate is 0.0075 mol/ dm³. Show clearly on the graph how you worked out your answer

c) Explain why the speed of reaction increases when the concentration of sodium thiosulfate is increased.

e) sketch on the grid the line you would expect if the experiments were repeated at a higher temprature.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
