- A form 4 student carried out an experiment with 40 cubic centimeters of 1.0M hydrochloric acid and Marble...(Solved)
Rates and reactions:
A form 4 student carried out an experiment with 40 cubic centimeters of 1.0M hydrochloric acid and Marble chips in order to determine rates of reaction using the following steps.
??HCL was poured to a conical flask
??Conical flask was then placed on a weighing balance
??20 grams of marble chips was then added to acid and left for reaction to proceed
??With time, Changes in mass of flask with contents was recorded
(a) State other way in which one can measure rate of reacion(1mk)
(b)(i) Sketch curve that will be obtain if mass of contents in flask is plotted against time label it as (k) (2mks)
(ii) Using the same axes sketch curve that will be obtain if powdered marble had been used(1mk)
(c) Write a chemical equation to show how reaction proceed (1mk)
