Question

Find the formula of following terms by crisscross method

Magnesium oxide
potassium nitrate
aluminium chloride
lithium oxide
sodium sulphide.​

Answer 1

Answer:

Magnesium oxide = Mg. O

X

2+. 2-

= +2 and -2 will be cut . and hence , the Formula will be MgO

Potassium nitrate = k NO3

X

1+. 1-

= same again , +1 and -1 will be deducted and hence , the Formula will be KNO3

Aluminium chloride = Al Cl

X

3+. 1-

= -1 charge it can be also considered as just Cl^- . so , Formula would be AlCl3

Lithium oxide = Li O

X

1+. 2-

= Formula will be Li2O

Sodium sulphide = Na S

X

1+. 2-

= 1 can just be considered as positive change so , the Formula would be Na2S

Hope you understood . please if it is so , mark my answer as brainliest .....
