Answer:
In order to take steps by humans for controlling the change in climate.
Explanation:
It is important that scientist find out the change which occurs in the climate with the passage of time by performing experiments and also repeat the experiments in order to verify their findings. Due to these experiments, scientists also find out the reasons behind of climate change which enable us to take steps in preventing the change that occurs in the environment. it is also important for scientists to be able to explain how they know that climate has changed over time in order to explain that he is not assuming or making predictions, he has to provide evidence for his statement which is only be possible through experiments.
Answer:
The amount of mass in a certain volume
Explanation:
Divide each by 4.7 to get ur kg/L which is 1.085kg/1L
4
Explanation:
The number 4 in the hydrologic cycle depicts surface runoff.
The hydrologic cycle depicts the cyclic movement of water between different earth components.
It shows water in all its phases.
- From the attached image, runoff is depicted 4.
- Runoff is water that moves on the surface after precipitation.
- Number 1 is evaporation where water changes to vapor.
- Number 2 is condensation where the vapor cools back to liquid.
- Number 3 is precipitation where the liquid water is forced down under gravity.
- On the surface, the water runs as runoff.

An acid-base reaction or a neutralization reaction is a <u>chemical reaction that occurs between an acid and a base producing a salt and water</u>. The acids and bases can be strong or weak depending on their degree of ionization in water.
Butyric acid is a weak acid and in water it is ionized in the following way, loosing a proton (H+):
HC4H7O2 (aq) ⇆ H+ (aq) + C4H7O2- (aq)
On the other hand, potassium hydroxide is a strong base, so it will be completely ionized in water:
KOH(aq) → K+(aq) + OH-(aq)
Then the <u>net acid-base reaction</u> between butyric acid and KOH is:
HC4H7O2 (aq) + OH- (aq) ⇆ H2O + C4H7O2- (aq)
It is valid to consider only the OH- produced from the ionization of KOH in water since, as mentioned, this molecule is completely ionized. Also, we do not include the K + in the net equation since it is a spectator ion, it does not undergo chemical changes.
