Although xenon and neon are noble gases and therefore do not typically form bonds, weak attractive forces do exist between atoms of these substances. Choose the statement that best explains why xenon has a higher boiling point than neon. a. Xenon has a smaller atomic mass than neon
b. Xenon has more electron than neon
c. Xenon forms more hydrogen bonds than neon
d. Xenon is more polar than neon

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.)
