DEMO

Sokheang experiments to find how fast 5 cm pieces of magnesium ribbon dissolve in 15 cm3 samples of sulfuric acid at different temperatures. Which piece of apparatus does he NOT need?

1. balance
2. measuring cylinder
3. stop-clock
4. thermometer

Sak was provided only a thermometer, a stopwatch and a beaker. What could he measure?

1. 
2. 
3. 
4. 

Part of the instructions in an experiment reads as follows. 

Quickly add 50 cm3 of acid.

What is the best piece of apparatus to use?

1. a burette
2. a conical flask
3. a measuring cylinder
4. a pipette

Jeena adds 1.5 g of calcium carbonate to 15 cm3 samples of dilute hydrochloric acid at different temperatures. She measures how long it takes for the bubbling to stop. Which apparatus does she use?

Lisa adds 5 g of calcium carbonate to 25 cm3 samples of dilute hydrochloric acid at the same temperature. She measures how long it takes for the bubbling to stop. Which apparatus does she use?
