Question
How many moles of h2 are produced from 0.2000g of Zn? Zn+2HCI--> ZnCl2+H2 Please show how you got your answer
Exp. 2 Took a 250 mL Erlenmeyer flask and a 50 mL graduated cylinder and added 45ml 6.0 M HCI to the graduated cylinder, then transferred it to the flask. Closed the flask and added a pressure gauge and thermometer. Initial measurements are as follows: pressure= 1.000 atm temperature= 21.5 c 1 Took a balance and a 50 mL beaker, then placed the beaker on the balance (zeroed out). Added 0.200g of zinc to the beaker. Initial mass read on balance =0.200g. Transferred zinc in the beaker to the 250ml flask with 6.0m HCI. The zinc dissolved and bubbled. The pressure increased and so did the temp. Once the flask cooled to room temp (21.5c), the thermometer and pressure gauge were removed. A gas syringe was then attached to the flask. The volume of the gas syringe read 73.63 mL O W 66°F 100 E-
