9. 6.59 g of ammonia (nh3, 17.031 g/mol) react completely in the presence of excess carbon dioxide (co2, 44.01 g/mol) according to the following balanced equation,
2nh3(g) + co2(g) → ch4n2o(s) + h2o(l) if 7.40 g of urea (ch4n2o, 60.056 g/mol) are produced,
calculate the percent yield for the reaction.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
