Question

The following steps are pan of the procedure followed in this experiment. Arrange them in order of their time of use. Remove the hose clamp on bottom hose close to trough. Slowly add HCl from burnt until 10 00 ml have been added. Weigh desired mass (plusminus 0.01 g) of metal recording all digits shown on balance and place in clean dry sidearm flask. Add a few drops of HCl to sidearm flask to start reaction. Record volume of gas in the graduated cylinder, water temperature and atmospheric pressure. Select one: 1, 3, 4, 2, 5 3, 1, 4, 2 5, 3, 4, 1 3, 4, 2, 1 3, 4, 1, 2, 5

Explanation / Answer

Typically, we record final volume at the end, so 5 must go at the end, since we must take final conditions at the end of experiment.

ignore C

a,b,d,e

Typically, we weigh the mass we are going to use FIRST, since we will not be able to get the mass any later... s ignore A...

b,d,e left

We typically add few drop os HCl so it starts reaction and it is not violent, so

ignore B

only D and E are left

the only thing that changes in procedure is 1 and 2..

Note that we will need to FIRST remove hose clamp, in order to be able to releas HCl drops

so

1 goes first than 2

choose E
