At constant temperature what happens to the pressure when the volume is doubled

Chemistry
1 answer:
IgorC [24]3 years ago
7 0

Answer:

For a fixed mass of gas at constant temperature, the volume is inversely proportional to the pressure.

Explanation:

For example, if you double the pressure, it will halve the volume. And if you increase the pressure by 10 times, the volume will decrease 10 times.

Which of the following reactions could be used to power a battery because of the transfer of electrons?
Trava [24]

Answer is: Zn + Cu2+ → Zn2+ + Cu.

In this chemical reaction, there is transfer of electrons from zinc (Zn) to copper (Cu). Zinc change oxidation number from 0 to +2 (lost electrons) and copper change oxidation number from +2 to 0 (gain electrons).

Oxidation half reaction: Zn⁰ → Zn²⁺ + 2e⁻.

Reduction half reaction: Cu²⁺ + 2e⁻ → Cu⁰.

In other chemical reactions, there is no change of oxidation number of elements.

How can bonding determine the properties of a substance?
miskamm [114]

Answer:

Explanation:

Chemical bonds are the forces that held the atoms in a molecules together. The strength of the bonds determine the some physical properties of material for example their hardness, solubility, boiling point, melting point etc. The stronger the bond , stronger will be the forces between them and it make difficult to separate the atoms.

There are three common type of bonding between atoms.

Ionic bonding

Covalent bonding

Metallic bonding

Ionic bonds are formed by complete transfer of electronic from one to another atoms. The compound having ionic bonds generally have moderate to high boiling points and melting point because of greater electrostatic interaction. Their electrical conductivity are high and these minerals tend to dissolve in water.

Covalent bonds are formed as a result of sharing of electrons between atoms. These compounds are insoluble , hard, having low melting and boiling points and have low conductivity.

The metallic bond is formed when metals are present. Due to loosely bound electrons of metals, electrons are shared with the other atoms. This is a type of covalent bond but it is not a true covalent bond. Th mobile electrons import great electrical conductivity in material. As this is a weak bond so these materials have low melting and boiling points.
