Answer:

Both A and B will be unreactive!

Explanation:

10=2, 8

18=2, 8, 8

Answer: Option (c) is the correct answer.

Explanation:

It is given that atom A contains 10 electrons so, its electronic distribution is 2, 8. Whereas atom B contains 18 electrons so, its electronic distribution is 2, 8, 8.

Since, both these atoms have completely filled octet so they do not need to react with any other element in order to attain stability.

Therefore, both these elements are unreactive in nature.

Thus, we can conclude that both A and B will be chemically unreactive.

10.Using the below valency chart, write chemical formula for aluminum oxide and
sweet [91]

The chemical formula of aluminum chloride is AlCl₃ and the  chemical formula of aluminum oxide is Al₂O₃.

<h3>Aluminum chloride</h3>

The chemical formula of aluminum chloride is written as;

Al³⁺  + Cl⁻   → AlCl₃

<h3>Aluminum oxide</h3>

The chemical formula of aluminum oxide is written as;

Al³⁺  + O²⁻   → Al₂O₃

Thus, the chemical formula of aluminum chloride is AlCl₃ and the  chemical formula of aluminum oxide is Al₂O₃.

What is the density of chlorine gas (MM = 71.0glmol) at 1.50 atm and 25.0C
IrinaVladis [17]

Answer: D=4.35g/L

Explanation:

The formula for density is D=\frac{M}{V}. M is mass in grams and V is volume in liters.

Since we are give pressure and temperature, we can use the ideal gas law to find moles/volume. FInding moles/volume would give us the base for density. All we would have to do is convert moles to grams.

Ideal Gas Law: PV=nRT

\frac{n}{V} =\frac{P}{RT}

\frac{n}{V}=\frac{1.50 atm}{(0.08206Latm/Kmol)(25+274.15K)}

\frac{n}{V} =\frac{0.061309mol}{L}

Now that we have moles, we can use molar mass of chlorine gas to find grams.

0.061309mol*\frac{71.0g}{mol} =4.3529g

With our grams, we can find our density.

D=\frac{4.3529g}{L}

We need correct significant figures so our density is:

D=\frac{4.35g}{L}

Carlos is looking at a picture of a convergent boundary on which a volcanic arc and a trench are identified. Which type of conve
Elan Coil [88]

The answer would be:

Oceanic-Oceanic Convergent Plate

This is why:

When two oceanic plates collide, the heavier of the two would subduct or in other words, go under the other plate. When this happens, ocean trenches and volcanic arcs form. The trench forms at the point oceanic plate goes under the other plate. And above the other plate that goes over create volcanic arcs.
