So scientist around the world can share there info without having to convert and doing extra work.
Answer:
Surface runoff and condensation
Explanation:
Let's define each of the given processes in order to understand them better:
- evaporation is a process in which liquid phase transforms into a gas phase;
- precipitation is a process in which we produce a solid phase, usually this is the case when we precipitate a salt out of a solution, analogy of precipitation for water would be transformation from a liquid to a solid phase, such as freezing;
- surface runoff is a process in which water flows over the surface of a land without any change in its phase;
- condensation is a process in which a gas transforms into a liquid.
All in all, notice that surface runoff keeps water in its liquid state, while all the other three options consider phase change. The only phase change of interest is condensation: we produce liquid water from water vapor and then we can analyze its movement in the liquid state.
The answer is 0.375 mol of silver chromate
A. a mixture is a combination of two or more substances in which each substance retains its own properties.
