NEED HELP ASAP!! I need help with these 2 questions! Please & thank you!

“Give an example of an ionic reaction, and explain it. “

And

“Give an example of a covalent reaction, and explain it”

Answer

covalent reaction: If two atoms share electrons, in order to have a completely filled outer shell then the bond formed between the two atoms is called, covalent bond. Covalent bond is the strongest of all the chemical bonds.

Ionic reaction:I ionic reaction is the one in which the electrolytes are represented as dissociated ions. ionic bond formed when the atoms are held together by the attraction forces between the oppositely charged ions. EX. in sodium chloride, sodium atoms are held together by ionic bonds.

hope this helps! sorry for answering late, like reay late, Have a nice day tho! :)

Explanation:

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

pure substance: iron,copper

impure substance: water,charcoal
