C.)  Average speed = total distance/total time. Total time= avg speed x time = 60x2 = 120miles.

A salt could be formed by an alkali metal and a(n)a. halogen.
b. metalloid.
c. transition metal.
d. alkaline-earth metal.

Answers

Answer is (A) - halogen.


Salts are inorganic and ionic compounds which are made from two ions. One is cation which has a positive charge and other one is anion which carries a negative charge. The overall charge of the salt is zero means the salt is neutral.


Alkali metals form salts with halogens like F, Cl, Br, and I. Here,the cation is alkali metal and halogen is the anion.

A salt could be formed by an alkali metal and a halogen. The answer is letter A. A halogen is example of nonmetal. The answer is letter A. When compounds containing halogens they are called salts thus the name “salt – former”. Halogen consists of Fluorine, Chlorine, Bromine, Iodine, Astatine.

Which equations shows the complete dissociation of a strong base? HCl -> cl- + H+

HNO2 -> H+ + NO2-

HA + h20 -> A- + H+ + h20

BOH + h20 -> B+ + OH- + H20

Answers

The correct answer is the fourth option. The complete dissociation of a strong base is BOH + h20 -> B+ + OH- + H20 since this is the only base from the choices given. A base is a substance that accepts hydrogen ions. 

Answer : The correct option is, (4) BOH+H_20\rightarrow B^++OH^-+H_20

Explanation :

Strong acid : Strong acids are those acids which are completely dissociates into ions in water. It dissociates into hydrogen ion and an anion.

Strong base : Strong base are those base which are completely dissociates into ions in water. It dissociates into hydroxide ion and a cation.

In all the given options, option (4) BOH+H_20\rightarrow B^++OH^-+H_20 equation shows the complete dissociation of a strong base.

While the other options shows the complete dissociation of an acid.
