The correct answer should be A.Ca and Br. A salt consists of a metal and a nonmetal, and a positive and negative charge. Ca (Calcium) is a metal and Br (Bromine) is a nonmetal, Ca is a +2 charge and Br is a -1 charge, so this is the only correct answer. Hope this helps :)

The good ozone protects us from the UV/ harmful radiations whereas bad ozone is an air pollutant.

Explanation:

  • There are two types of ozone layer found in the earth's atmosphere extending from troposphere to stratosphere. They are good ozone and bad ozone.
  • Bad ozone as mentioned earlier it is an air pollutant and found in the ground level of earth, most accurately the troposphere. Bad ozone is formed in the ground level of earth's atmosphere by the reaction between nitrogen oxides and organic compounds which are volatile
  • The Good ozone is found in the stratosphere layer of the earth's atmosphere. They protect us from harmful radiations. Good ozone layer in the stratosphere of the atmosphere is being destroyed by hydrocarbons, CFCs, and human intervention

Which factor is generally responsible for high melting points?
kherson [118]
The factor that is generally responsible for higher melting point is intermolecular forces. The compounds that are covalent in nature are made of molecules rather than ions. It has been seen that some of the covalent compounds have polar molecules at one end, due to which the one end has more electronegative force than the other. The electrostatic force that is bounding the compound is the main cause of higher melting point of this compound.  So it is true that with the increase of polarity of a compound creates higher melting point. .. hope I helped
