<u>Answer:</u> Yes, metals and non-metals forms ionic bonds.
<u>Explanation:</u>
Ionic bond is defined as the bond which is formed by complete transfer of electrons from one atom to another atom.
The atom which looses the electron is known as electropositive atom and the atom which gains the electron is known as electronegative atom. This bond is usually formed between a metal and a non-metal.
<u>For Example:</u> Formation of sodium chloride
Sodium is a metal and is the 11th element of periodic table having electronic configuration of
To form ion, this element will loose 1 electron.
Chlorine is a non-metal and is the 17th element of periodic table having electronic configuration of .
To form ion, this element will gain 1 electron.
By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
So, the compound formed between sodium and chlorine atom is NaCl
Hence, metals and non-metals forms ionic bonds.
Answer: a. 0.106mol
b. 5.93moles
Explanation: Please see attachment for explanation
The equation of the function is assumed to be a straight line is of the form,
, where
are the gradient and the y intercept respectively.
The gradient is computed using the formula for the gradient, i.e
.
The equation of the line is,
The equation of the function is ,
.
The value of the x-coordinate when the y coordinate is 0 is found as shown below.
.
so the x-coordinate is 1.
