If we define motion, it is a change of position of an object over time. The change of position would indicate distance. Thus, the most appropriate scientific description of motion would be
<span>the distance an object travels in a given time</span>
Answer:
C
Explanation:
Oil is less dense than water so it will always seperate and float on top of the water.
Answer: Destruction of the ozone
Explanation: Some of the he most common refrigerants used for air conditioning is chloroflurocarbons and hydroflurocarbon that can deplete the ozone layer that is a protective covering.
This covering filters the harmful rays of the sun that is harmful for the human beings and animals on the earth. The coolants contains chlorine which impacts the ozone and cause depletion.
Product of this reaction depends on the amount of oxygen.
i.) If oxygen is excess:
Carbon, as graphite, burns to form gaseous carbon (IV) oxide (carbon dioxide), CO2
Equation :
C + O2 ----> CO2. This reaction is also called combustion reaction. The expensive way to produce CO2 is to burn Diamond in the presence of air at 600-800°C. Hope it helped you. :D
It means there is a lot of the same thing and not many others
