Dominik [7]3 years ago
3 0

Answer:

C

Explanation:

Calcium is an element with a total of 20 electrons.

 It has 4 shells with a configuration of:

          2, 8, 8, 2

Option C is the most similar to calcium but the number of shells is not complete.

It still requires two more shells with 8 and two electrons respectively.

Juli2301 [7.4K]

Answer:

Explanation:

Nitrogen gas in nitrogen cylinder is in gaseous form only . So when gas is released , pressure decreases because moles of  gas in the cylinder decreases .

Propane gas in cylinder is in liquified form . The gas is partially in gaseous and liquid form . So when gas is released outside , pressure decreases inside but due to low pressure , some liquid form is converted into gaseous form which restores the pressure of gas inside cylinder . Hence , the pressure of gas remains unchanged inside cylinder.
