Question

Drag and drop the true statements into the box that apply when using weigh boats in the laboratory. Click on an appropriate statement, then drag it into the box.
1) in some cases, the same weigh boat will be used by all students.
2) the empty weigh boat must be tared (set to zero) before adding material.
3) a paper towel should not be used to transfer product out of a weigh boat.
4) the balances in the lab can be zeroed out with a weigh boat on the balance.
5) plastic weigh boats can prevent spillage when weighing liquids into a beaker.

Answer 1

Answer:

1) in some cases, the same weigh boat will be used by all students: This is True, but the weigh boat must be properly labelled with the compound that is intended to be weighed.

2) the empty weigh boat must be tared (set to zero) before adding material.: This is true because to get accurate weight, it is required to tare the empty weigh boat so as to get the weight of the material alone and not factor in the weight of the empty weigh boat.

3) a paper towel should not be used to transfer product out of a weigh boat: This is true because you want to ensure that no impurities is mistakenly added into the material that is being weighed.

4) the balances in the lab can be zeroed out with a weigh boat on the balance: This statement is true because there must be a counter weight to zero an already existing balances.

5) plastic weigh boats can prevent spillage when weighing liquids into a beaker: This is True because the plastic would help to ensure that the liquids is directly poured into the beaker without spillage.
