Answer:
= 200 mL
Explanation:
Using the dilution formula;
M1V1 = M2V2 ;
Where, M1 is the concentration before dilution, V2 is the volume before dilution, while M2 is the concentration after dilution and V2 is the volume after dilution.
M1 = 2.0 M
V1 = 50 mL
M2 = 0.50 M
V2 = ?
V2 = M1V1/M2
= ( 2.0 × 50 )/ 0.5
= 200 mL
Therefore, the volume after dilution will be, 200 mL
Potassium chloride
Potassium is the metal cation and chloride is the nonmetal anion
All the other options have two non metals
Answer. c and d both statements are correct.
Explanation:
Statement A is incorrect because anions are the species which are negatively charged.
.
Statement B is incorrect because non metals generally forms anions for example:
Statement C is correct because when we write an ion we will first write symbol of that element than charge and then positive(cations) or negative(anions) sign. for example
.
Statement D is correct because when anion is formed, electrons are gained.These number of electron depends upon the valency of that element.
