Determine the mass in grams of NH3 formed from 1.34 moles of nitrogen
what is the equilibrium constant expression for co2(g)+h2(g)⇌co(g)+h2o(g)
If 2.85 moles of H₂ and 1.55 moles of O₂ react how many moles of H₂O can be produced in the reaction below?
2 H₂(g) + O₂(g) → 2 H₂O(g)
Copper can be found as a free metal, but most often it is found in a compound with sulfur. The ore is heated with oxygen to change it to copper oxide. Sulfur dioxide gas also is formed. Write a balanced chemical equation for this reaction. [You must include state: (s), (l), (g), (aq).]
. Catalase is an important enzyme that breaks down its substrate, H2O2, into water and oxygen in nearly all living cells. The enzyme has k2 = 1.1*107 sec-1 and Km = 2.0 mM. An experiment was set up under the conditions when the reaction rate is independent of [H2O2]. In this experiment, at what concentration of catalase (use SI units and scientific notation) will the reaction have a rate of 850 mM/min?
