1.A student is asked to measure the time taken for 4.00g of magnesium carbonate to react completely with 25.0 cm3 of dilute hydrochloric acid.
Which pieces of apparatus does the student need?

A: Balance, clock, pipette
B: Balance, clock, thermometer
C: Balance, pipette, thermometer
D: Clock, pipette, thermometer
My answer is c so correct me if I am wrong.

  1. Hi Ochaya,
    The answer is A.

    You were right that you need a balance to measure the grams of MgCO3 and a pipette to add HCI, but you don't need a thermometer-- after all we're measuring the /time/, so you need a clock.
