What does Boyle's law state about the relationships among temperature, volume, and pressure?
When the pressure of a gas decreases, the volume and the temperature of the
gas both increase.
As the volume of a gas increases, the temperature and pressure of the gas both
decrease.
Provided temperature remains constant, the volume and pressure of a gas are
inversely related
When the temperature of a gas increases, the volume and pressure of the gas
both decrease.

How do scientists think that gravity affected the formation of our solar system?

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.)

How many moles of potassium are needed to react completely with 12.8 moles of magnessium bromide?
