Answer: Option (a) is the correct answer.

Explanation:

Non-metals are the species which in order to complete their octet readily gain an electron.

For example, fluorine is a non-metal with atomic number 9 and its electronic distribution is 2, 7.

Hence, to attain stability it readily accepts an electron from a donor atom.

Some characteristics of non-metals are as follows.

Non-metals do not conduct electricity.

Non-metals are brittle in nature and they have a rough surface.

Non-metals are not malleable or ductile.

Thus, we can conclude that non-metals do not conduct electricity is a characteristic of non-metals.

Sally has constructed a concentration cell to measure Ksp for MCln. She constructs the cell by adding 2 mL of 0.05 M M(NO3)n to

hram777 [196]

Answer:

0.1056 mole

Explanation:

As Sally knows that the charge on the metal ion is n = +2

$MCl_n=MCl_2$

In that compartment $[M^{n+}]=[m^{2+}]=8.279 \ M$

The volume of the $MCl_n$ taken in that compartment = 6.380 mL

So, the number of moles of $M^{2+} = 8.279 \times 6.380$

= 52.82 m mol

= 0.05280 mol

$MCl_n \rightarrow M^{n+}+nCl^-$

But n = 2

Therefore, moles of $Cl^-$ = 2 x moles of $M^{n+}$

= 2 x 0.05282

= 0.1056 mole

according to the third law if a football player hits another player with an action force of 1500n how much will the reaction for

djyliett [7]

Answer:

The reaction would be 1500n (equal reaction)

Explanation:

This can be explained by Newton's third law of motion which states that for every action (force), there is an opposite and equal reaction. In other words, when two objects or people come in contact, the magnitude of force which they exert on each other is equal and they both feel an equal reaction force.

It doesn't matter whether one of the colliding bodies is of bigger mass than the other. This Newton's third law of motion is also known as the law of action and reaction.

How many moles of KCl are required to prepare 1.50 L of 5.4 M KCl?

puteri [66]

5.4 M = moles of solute / 1.50 L

<span>Multiply both sides by 1.50 L to isolate moles of solute on the right. </span>

<span>8.1 mol = moles of solute </span>
