Well when the sun makes water dissaper thats usually evaporation.
The chemical changes is when the plants absorb the energy from the sunlight and convert water and carbon dioxide into sugar and oxygen gas. Physically nothing has changed. The plant still looks the sam changes occur internally these internal changes are chemical in nature.
Answer:
yes it can
Explanation:
because, it depends on where the rock is, for example on a dessert it would Be cracked and things like that if near an eruption it would be the flamey black rock, and so on you get it
Answer: humans would find more efficient ways of growing crops
Explanation:
Answer : The pH of the solution is, 1.25
Explanation : Given,
Concentration (C) = 0.056 M
The equilibrium reaction will be,
From the balanced chemical reaction, we conclude that
1 mole of 
dissociate to give 1 mole of 
ion
So, the concentration of = the concentration of = 0.056 M
Now we have to calculate the pH.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
Therefore, the pH of the solution is, 1.25
The measured bond<span> angles of these compounds (H</span>2O 104.5º & NH3<span> 107.3º) show that they are closer to being tetrahedral than trigonal or linear. Of course, it is the configuration of atoms (not electrons) that defines the the </span>shape of a molecule<span>, and in this sense ammonia is said to be pyramidal (not tetrahedral).</span>
