The compound AB₂ is a covalent compound.

<h3>What is the nature of the molecular substance AB₂?</h3>

The nature of a substance depends on the component elements and the nature of the bonds present in the substance.

Substances can be ionic in nature if ionic bonds are present in the compound or covalent in nature if covalent bonds are present.

The substance AB₂ is composed of the elements A and B where A is a group 14 element and B is a group 16 element.

Group 14 elements are usually non-metals or semi-metals.

Group 16 elements are non-metals.

The bond between A and B will be covalent. Therefore, the compound AB₂ is a covalent compound.

A sample of gas in a balloon has an initial temperature of 21 ∘C and a volume of 1310 L . If the temperature changes to 70 ∘C ,
bixtya [17]

Answer:

1528.3L

Explanation:

To solve this problem we should know this formula:

V₁ / T₁ = V₂ / T₂

We must convert the values of T° to Absolute T° (T° in K)

21°C + 273 = 294K

70°C + 273 = 343K

Now we can replace the data

1310L / 294K = V₂ / 343K

V₂ = (1310L / 294K) . 343K → 1528.3L

If the pressure keeps on constant, volume is modified directly proportional to absolute temperature. As T° has increased, the volume increased too

My name is Ann [436]

Answer:

Decomposition reaction.

Explanation:

Decomposition reaction -

It is the type of reaction, where a single entity breaks down into various products under the influence of some external factors , like heat and sunlight , is referred to as a decomposition reaction.

From the question,

The reaction is -

2 HgO  →  2 Hg + O₂

Hence ,

A single compound HgO breaks down to two entities , i.e. , Hg and  O₂.

brilliants [131]

Answer:

16.92 g C13H18O2

Explanation:

If the molecular mass of C13H18O2 is 206.3 amu, then molar mass of C13H18O2 is 206. 3 g/mol.

So, if we have 0.082 mol C13H18O2, than it is

206.3 g/mol*0.082 mol = 16.92 g C13H18O2.
