Consider the chemical reaction 2nh3(g) n2(g) + 3h2(g). the equilibrium is to be established in a 1.0 l container at 1,000 k, where kc = 4.0 × 10–2. initially, 1,220 moles of nh3(g) are present. estimate the equilibrium concentration of h2(g).

Draw the skeletal structures of two different molecules that are each made of 5 carbon atoms and 12 hydrogen atoms.

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
