Acomatose infant is brought to the er. in the course of the examination, plasma ammonia was found to be elevated 20-fold over normal values. urine orotic acid and uracil, that require carbamoyl phosphate for their formation, were both greater than normal. a defect of which of the following enzymes is the most likely diagnosis? a. arginaseb. argininosuccinate lyasec. carbamoyl phosphate synthetase 1 (ammonia substrate)d. carbamoyl phosphate synthetase 2 (glutamine substrate)e. ornithine transcarbamoylase

Problem page combustion of hydrocarbons such as pentane ( c5 h12 ) produces carbon dioxide, a "greenhouse gas." greenhouse gases in the earth's atmosphere can trap the sun's heat, raising the average temperature of the earth. for this reason there has been a great deal of international discussion about whether to regulate the production of carbon dioxide.(a) write a balanced chemical equation, including physical state symbols, for the combustion of liquid pentane into gaseous carbon dioxide and gaseous water. (b) suppose 0.350 kg of pentane are burned in air at a pressure of exactly 1 atm and a temperature of 20.0 degree c. calculate the volume of carbon dioxide gas that is produced. be sure your answer has the correct number of significant digits.

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
