Answer:
<h2>377 kPa</h2>Explanation:
The original pressure can be found by using the formula for Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the original pressure
150 kPa = 150,000 Pa
We have
We have the final answer as
<h3>377 kPa</h3>Hope this helps you
Explanation:
A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.
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 or the metal and the element which accepts the electrons is known as electronegative element or non metal.
a. contain covalent bonds as they are made up of non metals only.
b. contain ionic bonds as they are made up of sodium metal and fluorine non metal.
c. contain covalent bonds as they are made up of non metals only.
d. contain ionic bonds between
and
and covalent between N and H in
