Calculate the change in heat when 14.50 g of water vapor (steam) at 100.0°C condenses to liquid water and then cools to 29.50 °C.
please show work. my professor did like 2 examples in lecture and did not do a problem like this.

100 points answer quick the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?

Which of the following is most likely true about water in chemical solutions?
