Lewis structure cannot show the numbers of valences
Explanation:
A chemical property is defined as the property that brings changes in chemical composition of a substance.
For example, flammability, combustion, reactivity, electronegativity etc are allchemical properties.
On the other hand, a property that does not bring any change in chemical composition of a substance is known as a physical property.
For example, shape, size, mass, density etc are all physical properties.
Thus, we can conclude that these may all be classified as chemical properties of a substance.
Answer:
The answer is
<h2>11.25 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 45 g
volume = 4 mL
Substitute the values into the above formula and solve for the density
We have

We have the final answer as
<h3>11.25 g/mL</h3>
