Why do gases take up so much space?

Answers

Gases take up so much space because the gas molecules are vibrating and moving very fast and in order to do this the molecules should as far as they could be to each other. They occur at low pressures and high temperatures where they can move freely in a container.

Given the balanced equation representing a reaction:6Li +N2 --> 2Li3N
Which type of chemical reaction is represented by this equation?
(1) synthesis (2) decomposition
(3) single replacement (4) double replacement

Answers

Answer : The correct option is, (1) synthesis

Explanation :

Synthesis reaction : A type of chemical reaction in which multiple reactants combine to form a single product.

It is represented as,

$X+Y\rightarrow XY$

Decomposition reaction : A type of chemical reaction in which a single reactant decomposes into two or more products.

It is represented as,

$XY\rightarrow X+Y$

Single replacement reaction : A type of chemical reaction where the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

(A is more reactive element and B is less reactive element)

Double replacement reaction : A type of chemical reaction in which a positive cation and a negative anion of two reactants exchange their places to form two new products.

It is represented as,

$AB+CD\rightarrow AD+CB$

(A and C are the cations, B and D are the anions)

The given balanced reaction is,

$6Li+N_2\rightarrow 2Li_3N$

The given reaction is an example of synthesis reaction in which lithium combine with the nitrogen to form a single product as lithium nitride.

Hence, the correct option is, (1) synthesis reaction

(1) synthesis is the answer because only one product is formed~

What are the effects of baking powder solution on dilute hydrochloric acid solution

Answers

Combining an acid with a base typically results in water and salt. In some cases, these reactions release gas and heat as well. Mixing baking soda, or NaHCO3, with hydrochloric acid, or HCl, results in table salt, NaCl, as well as water, H2O, and carbon dioxide, CO2.

A white solid is flammable and dissolves in hexane. Would you expect this compound to be organic or inorganic?

Answers

A white solid is flammable and dissolves in hexane. It should be organic molecule.

What is organic molecule.?

Any chemical substance that has carbon-hydrogen, as well as carbon-carbon bonds is considered an organic molecule.

What is flammable?

The term "flammable substances" refers to those gases, liquids, as well as solids that, when exposed to an ignition source, would catch fire and keep burning in the air. Many flammable and explosive substances have a volatile character, which means they rapidly evaporate and continuously emit vapors.

A chemical characteristic, like corrosion resistance, was flammability. A material's physical characteristics, including its hardness, density, melting point, and thermal conductivity, can be measured or observed without using force or chemical alterations. A material's phase changes when it melts, not just its identity.

There are some properties of organic molecules.

An abundance of carbon.
Saturation in organic solvents.
Covalent bonds form
A low boiling as well as melting point.

The answer is organic. The most important hint is it can dissolves in hexane which is organic. And the other hint is flammable. Then you can say this compound is likely to be organic.

Which lists the elements in order from least conductive to most conductive?A. nitrogen (N), antimony (Sb), bismuth (Bi)
B. nitrogen (N), bismuth (Bi), antimony (Sb)
C. antimony (Sb), nitrogen (N), bismuth (Bi)
D. bismuth (Bi), antimony (Sb), nitrogen (N)

Answers

Answer: Option (A) is the correct answer.

Explanation:

Nitrogen is a non-metal and it is known that non-metals do not conduct electricity. Thus, it will be least conductive out of the given options.

Whereas antimony (Sb) is a metalloid. Metalloid are the substance that show properties of both metals and non-metals. Thus, antimony will conduct electricity.

On the other hand, bismuth (Bi) is a metal hence, it will conduct electricity.

Thus, we can conclude that the order from least conductive to most conductive will be nitrogen (N), antimony (Sb), bismuth (Bi).

Answer: The correct answer is Option A.

Explanation:

Conductivity of an element is defined as the tendency to conduct electricity. This property is shown mostly by metals and then by some metalloids and least by non-metals.

Metals are defined as the elements which loose electrons easily and thus can easily conduct electricity due to the presence of free electrons.

Metalloids are defined as the elements which show the properties of both metals and non-metals. Some metalloids are conductive, some are not.

Non-metals are defined as the elements which gain electrons easily and thus cannot conduct electricity easily and are considered as non-conductive.

From the given options:

All the three elements belong to same group but nitrogen is a non-metal, antimony is a metalloid and Bismuth is a metal.

Thus, the order of conductivity follows:

$\text{Nitrogen }<\text{Antimony }<\text{ Bismuth }$

Hence, the correct answer is Option A.
