Explanation:

As it is given that the element contains a total of 8 electrons. So, electronic distribution of this element will be 2, 6.

That is, there will be two electrons present in first shell and there will be six electrons present in second valence shell.

Here, we also get to know that this element contains 6 valence electrons hence, it is a group 16 element.

Thus, we can conclude that if an element contains 8 electrons then 6 electrons will be placed in the 2nd valence shell.

If an element contains 8 electrons, then there would be 6 electrons that will be placed in the 2nd valence shell. Each shell in an atom can only take up a fixed number of electrons. For the first shell, only two electrons can be found. For the second shell, it can hold up to 8 electrons. However, for this case only six electrons can be found since the others are found in the first shell.

14. Convert 4084 grams of NH3 kept at -40°C to Liters at STP. The density as a liquid is
Zigmanuir [339]

The density of the gas can be given by the mass of the substance and its volume. A 4084 gms of ammonia has a volume of 5.99 L.

<h3>What is STP?</h3>

STP is the condition at which the temperature and the pressure of the gas are at the normal and standard conditions.

The density of the ammonia = 681.9gm/L

The mass = 4084 gm

The volume is calculated as:

V = Mass ÷ Volume

= 4084 ÷ 681.9

= 5.99 L

Therefore, at STP the volume of ammonia is 5.99 L.

Predict the chemical formula of the compound that will form when Li and o interact.
Ksivusya [100]

Answer:

Li_2O

Explanation:

Hello!

In this case, when looking over the chemical formula of a compound formed when two elements interact, we need to realize about their location in the periodic table; thus, since lithium is a metal and oxygen a nonmetal, we infer lithium turns out the cation and oxygen the anion. Moreover, as the oxidation state of lithium is 1+ and that of oxygen is 2-, we can set up the chemical formula as follows:

Li^+O^{2-}\\\\Li_2O

Best regards!

why do you think that sodium chloride has to be heated to 800c before melting, but candle wax will start to melt at 50c?
RideAnS [48]

Answer:

Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.
