Elemental carbon reacts with water to yield carbon monoxide and hydrogen. How many liters of hydrogen gas are formed from the complete reaction of 1.08 mol of C. Assume that the hydrogen gas is collected at a pressure of 1.0 atm and a temperature of 316 K.

If a reaction has g of -136kj at 110°c, will it be spontaneous at this temperature (110°c)? yes or no

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.)
