Answer:

Argon has 8 valence electrons making it non reactive.

Explanation:

Reactive chemicals are store in containers filled with Argon gas because the argon gas is non reactive. This is true because the argon gas has completely filled octet structure.

This can further be explained by writing the electronic configuration of argon.

The electronic configuration of argon is given below:

Ar (18) => 1s² 2s²2p⁶ 3s²3p⁶

Valence electron => 3s²3p⁶ = 2 + 6 = 8

From the above illustration, we can see that the outermost shell (i.e 3s²3p⁶) is having 8 electrons indicating that it is completely filled as the maximum number of electrons any shell can accommodate outside the first shell is 8 electrons. Thus, argon has 8 valence electrons ( i.e electrons in the outermost shell) and hence it is non reactive as the outermost shell is completely filled.

How many chlorine atoms are there in 100 g of carbon tetrachloride
Liono4ka [1.6K]

Answer:

1.566x10²⁴ atoms of Cl

Explanation:

In Carbon tetrachloride, CCl₄, you have 4 moles of Cl per mole of CCl₄. To solve this question we must find the moles of CCl₄ in order to find the moles of Cl. Using Avogadro's number we can solve the chlorine atoms:

<em>Moles CCl₄: 153.82g/mol</em>

100g * (1mol / 153.82g) = 0.65 moles CCl₄

<em>Moles Cl:</em>

0.65 moles CCl₄ * (4 moles Cl / 1mol CCl₄) = 2.6 moles Cl

<em>Atoms Cl:</em>

2.6 moles Cl * (6.022x10²³ atoms / mol) =

Marysya12 [62]

Answer:Reliability

Explanation:

Reliability of a test refers to how consistently a test measures a characteristic under the same conditions.

Reliability can be defined as the degree of consistency of which a chemical test gives a similar result. measure. A test is said to be highly reliable when it gives the same repeated result under the same conditions of measure.

But when a test gives different results under the same condition of measure it has a low reliability.

Hence, If a test yields consistent results every time it is used, it has a high degree of reliability.
