B. Magnesium + Hydrogen Sulfide (Reactors) ----> Magnesium Sulfide + Hydrogen (Products)
Ca-Cl is an ionic bond. We know this because the difference between their electronegativities is 2.16.The electronegativity tells us which atom will attract the electron more than the other. Hence, chlorine attracts the electron a lot more than the calcium.A difference of more than 1.6 (or 1.7 depending on the source) implies that the electrons are so unevenly shared, that the bond is ionic, rather than polar covalent.
6 electrons... 's' can hold 2..... 'd' can hold 10 and 'f' can hold 14

] value of soft drink is 0.0001mol/l when given pH is 4.
Given:
pH = 4
Needs to find: []
Formula to find: pH=−log
[]
We can put the values of pH in above formula as,
pH=−log []
4 =−log []
To calculate hydonium ion concentration, formula is as follows;
[] = 
[] = 
= 0.0001mol/l
