If 6.75 g of NaOH are dissolved in 50.00 g of water and the temperature increases from 20.5°C to 47.8 °C. a. Is this an example of an endothermic or exothermic reaction?

b. What is the q for the reaction? (Remember since the NaOH dissolves in water add the masses to get the m)

c. How many moles of NaOH are dissolved?

d. What is the ΔH for the reaction?

In vapor-liquid equilibrium in a binary mixture, both components are generally present in both phases. how many degrees of freedom are there for such a system? the reaction between nitrogen and hydrogen to form ammonia occurs in the gas phase. how many degrees of freedom are there for this system? steam and coal react at high temperatures to form hydrogen, carbon monoxide, carbon dioxide, and methane. the following reactions have been suggested as being involved in the chemical transformation:
