What volume (in L) of ethane (C2H6) will be required to produce 42.5 L of carbon dioxide in
the reaction below?
2C2H6(g) + 702(g) → 4CO2(g) + 6H2O(g)

What are the first three quantum numbers for the electrons located in subshell 2s?

Consider the following reaction at equilibrium. 2co2 (g) 2co (g) + o2 (g) h° = -514 kj le châtelier's principle predicts that the equilibrium partial pressure of co (g) can be maximized by carrying out the reaction a. at high temperature and high pressure b. at high temperature and low pressure c. at low temperature and low pressure d. at low temperature and high pressure e. in the presence of solid carbon
