Answer: Polar covalent
Explanation:
a) A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
Types of covalent bonds:
A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms. Example:
Non-polar covalent bond is defined as the bond which is formed when there is no difference of electronegativities between the atoms.Example:
b) An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal. Example:

Answer:
<h2>mass = 200.23 g</h2>Explanation:
The density of a substance can be found by using the formula
Since we are finding the mass
<h3>mass = Density × volume</h3>From the question
Density = 0.81 g/mL
volume = 247.2 mL
Substitute the values into the above formula and solve for the mass
mass = 0.81 × 247.2
= 200.232
We have the final answer as
<h3>mass = 200.23 g to 2 decimal places</h3>Hope this helps you
