Lead is more ductile than iron. The correct option is A. Lead is more ductile than iron
<h3>Young's modulus </h3>
From the question, we are to determine the statement which is true
First, we will define the term <em>Young's modulus </em>
<em>Young's modulus</em> is a measure of the stiffness of an elastic material. It is also given as the ratio of <u>stress </u>to <u>strain</u>. That is,
The greater the modulus, the stiffer the material.
Materials with low Young's modulus tend to be <u>ductile </u>and materials with high Young's modulus tend to be <u>brittle</u>
Since the Young's modulus value for iron is higher than that of lead, then iron is <em>stiffer </em>than lead.
Thus, lead is more ductile than iron. The correct option is A. Lead is more ductile than iron

It involved knots in strings called quipu. The quipu was not a calculator, rather it was a storage device. Remember that the Incas had no written records and so the quipu played a major role in the administration of the Inca empire since it allowed numerical information to be kept.

Answer:
Option (b) 0.67 M
Explanation:
The following Data were obtained from the question:
Mole of MgCl2 = 0.5 mole
Volume of solution = 750mL
Molarity of MgCl2 =?
Next, we shall convert the volume given from mL to L. This is illustrated below:
1000mL = 1L
Therefore 750mL = 750/1000 = 0.75L
Now we can obtain the molarity of MgCl2 as follow:
Molarity is defined as the mole of solute per unit litre of the solution i.e
Molarity = mole /Volume
Molarity = 0.5/0.75
Molarity of MgCl2 = 0.67 M
