Identify the substances that will appear in the equilibrium constant expression for the equation: 2 upper A g superscript plus (a q) plus upper Z n (s) double arrow upper Z n superscript 2 plus (a q) plus 2 upper A g (s). Check all that apply. Ag Zn Zn2 Ag.

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
