If carbon dioxide gas is collected over water at 25 °C and 775 torr, what is the partial pressure of the CO2? The vapor pressure of water at 25 °C is 24 torr. OPTIONS:
A. 23.8 torr
B. 750 torr
C. 751 torr
D.775 torr

Which feature do highland climates have that lower elevation areas do not?

How many liters of hydrogen gas will be produced at stp from the reaction of 7.179×10^23 atoms of magnesium with 54.219g of phosphoric acid (h3po4) the equation is 3mg + 2h3(> mg(po4)2+3h2

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
