If a 325 mL container of He gas with apressure of 0.8 atm increases its pressure to 1.5 atm, what is the resulting volume of the container?

How will the volume of a gas be affected if the pressure is tripled, but the temperature remains the same?

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.)

Which of the following is not an assumption that scientists must make about the natural world? a. regularity b. causality c. predictability d. plausibility
