Answer:
True
Explanation:
Acid rain is a type of acid deposition, which can appear in many forms. Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal. Dry deposition is another form of acid deposition, and this is when gases and dust particles become acidic.
I think this is true because the species evolved and adapted to the natural environments so perfectly that when a geological change such as global warming, the asteroid that hit earth etc. all affected climate, food or water.
Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
C
Dew point is the temperature of an air mass in which the water vapor (humidity) starts to condense into droplets due to saturation. This is when dew begins to form.
Explanation:
The higher the temperature the higher the water vapor the air mass can hold. This is because the intermolecular spaces between the air molecules become larger with increased temperature hence can accommodate more water vapor molecules in between the air molecules. As the air mass cools the intermolecular spaces become shorter and the relative humidity of the air mass increases. At temperatures where the air mass can't accommodate its humidity, this is called the dew point, and the water vapor begins to condense into droplets (dew).
