A reaction occurs when solid X is placed into solution Y.
As a result, the temperature of the new solution increases by 3°C the temperature rises another 2°C one more of the solid X is added to the solution. What does this indicate about the effect of adding more solid?

1. It increases the number of molecular collisions
2. Decrease molecular collisions
3 decreases the space between molecules
4. Increased the space between the molecules

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:
