What is the real gas pressure exerted by 1.00 mol of O2 at 300. K in 2.41 L if the ideal pressure is 10.0 atm? (a=1.360 L2atmmol2 and b=0.0318 Lmol). Your answer should have three significant figures.

Which of these best describes an ionic bond?

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)
