A student measures a pressure increase of 0.25 atm while collecting the H2 gas products from the reaction of Mg with HCl. The theoretical pressure change is 0.29 atm. What is the % yield

Thus the % yield is 86.2%

Explanation:

Percentage yield is the ratio of actual change to the theoretical change in terms of percentage.

The given reaction is :

To calculate the percent yield :

Given : Actual pressure increase = 0.25 atm

Theoretical pressure change = 0.29 atm.

Thus the % yield is 86.2%

is it a purebred? it looks more like a red nose, but it doesn't have the red could it be a staffordshire bull terrior? unsure if that's the right name for it sorry

particle   p is an electron and particle q is a neutron
