Question 1.
What does monitoring mass loss help measure in chemical reactions?
Show hintHide hint
Consider the relationship between mass loss and gas production.
Question 2.
Why is it important to weigh the reaction container at intervals?
Show hintHide hint
Think about why timing matters in measuring something that changes.
3Question 3.
What is monitored to measure the rate of a reaction in monitoring mass loss?
- The rise in temperature
- The decrease in mass
- The increase in volume
Show hintHide hint
Look for what changes in the reactant quantities.
4Question 4.
True or False: Mass loss is a direct measurement of gas produced in a reaction.
- True
- False
Show hintHide hint
Consider the implications of gas escaping.
Question 5.
A reaction produces a gas that leads to a 5g mass loss over 10 minutes. What would be the average reaction rate in grams per minute?
Show hintHide hint
Think about how to relate total mass loss with the duration.
Question 6.
If a container's initial mass is 120g and after some time it registers 110g while producing gas, calculate the mass of gas produced.
Show hintHide hint
Consider how mass conservation applies.
