Chemistry

The octet rule is that atoms must have 8 valence electrons to have an octet. Usually, when atoms have an octet, they tend not to bond with any other atoms because they are already stable and do not need to bond anymore.

This is a rule that says that atoms tend to combine to complete electrons to 8. And that means that the two atoms tend to combine to complete a shell to 8 electrons. Hope i helped. Have a nice day

Mashutka [201]

C.. it wants to try to remain in a state of equilibrium or equal

with that being said it wants to electrons to be equal to the number of electrons as much as possible

its like static friction when you rub a balloon on your head... you are replacing electrons for neutrons and that why it can stick to a wall after you rub it on your head because a wall only has negative atoms and when you rub the balloon on your head it takes some positive and charges it up positively and attracts to the negative atoms on the wall

How many moles are in 25.3 g of a sample of potassium nitrate (KNO3)?
aksik [14]

Answer:

25.3 g of KNO₃ contain 0.25 moles.

Explanation:

Given data:

Number of moles of KNO₃ = ?

Mass of KNO₃ = 25.3 g

Solution:

Formula:

Number of moles = mass/ molar mass

Molar mass of KNO₃:

KNO₃ = 39 + 14+ 16×3

KNO₃ = 101 g/mol

Now we will put the values in formula.

Number of moles = 25.3 g/ 101 g/mol

Number of moles = 0.25 mol

Thus, 25.3 g of KNO₃ contain 0.25 moles.
