0.15 grams of Mg is combined with HCl to produce H*2 gas. If the reaction occurs at 25°C in a 150 ml container, what is the theoretical pressure change?
102 kPa
% yield= theoretical yield/actual yield (100)
False
A student measures a pressure increase of .25 atm while collecting the H*2 gas produced from the reaction of Mg with HCl. The theoretical pressure change is .29 atm. What is the % yield?
86%
A student is collecting the gas produced from the reaction of 1.5 grams of Mg with excess HCl. When the reaction is complete, how many moles of H*2 should have been produced?
.062 moles
When 5 ml of HCl was added to the flask, 5 ml of air was removed. This was done so that _____.
There was still 140 ml of volume available for the reaction
When performing calculations with gases, it is appropriate to use the Celsius temperature scale.
False
