Consider the following reaction: How much energy would be released in the formation of 21.3 g of H20? (Note that the 15,026kJ is a product here)

2 C12H26(1) +
37 O2(g) —->
24 CO2(g) + 26 H2O) + 15,026 kJ

If the element whose electric configuration ends in the d sublevel, the element is calssified as? a. inner transition b. noble gases c. representative d. transition

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins. co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)

Consider the following reaction at equilibrium: c(s)+h2o(g)⇌co(g)+h2(g) predict whether the reaction will shift left, shift right, or remain unchanged upon each of the following disturbances. a) c is added to the reaction mixture. b) h2ois condensed and removed from the reaction mixture c) co is added to the reaction mixture d) h2 is removed from the reaction mixture.
