Areaction requires 22.4 l of gas at stp. you have 25.0 l of gas at 101.5 kpa and 373 k. which of the following statements is true? (use the ideal gas law: pv = nrt where r = 8.31 l-kpa/mol-k.)
a- you do not have enough gas for the reaction.
b- you will have gas for the reaction.
c- given this information, you cannot tell if you have enough gas for the reaction.
d- you will have excess gas for the reaction.

Nonpoint source pollution is difficult to control because it

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

All of the following are homogeneous mixtures except a) sugar dissolved in water. b) orange juice. c) coffee with cream. d) household vinegar. e) apple juice
