Unsaturated organic compounds with a carbon-to-carbon double bond and alkynes with a carbon-to-carbon triple bond, as well as aldehydes and ketones with a carbon-to-oxygen double bond, undergo addition reactions.

Answer:

Atomic number shows u the amount of protons there are in the atom

The protons are equal to the number of electrons

The group number tells  you  the number of electrons on the outer shell

(Sorry if u didn’t want the extra info but really it’s simple like magnesium has 12 so it has 12 protons/ 12 electrons)

Answer:

To calculate the numbers of subatomic particles in an atom, use its atomic  number and mass number:

1. number of protons = atomic number.

2. number of electrons = atomic number.

3.number of neutrons = mass number - atomic number.

Answer:

Vinyl chloride is an organochloride with the formula H2C=CHCl that is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC).

Explanation:

Answer:

CH2=CHCl

Explanation:

The volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.

The volume of a gas can be calculated using ideal gas law equation as follows:

PV = nRT

Where;

0.93 × V = 10 × 0.0821 × 145

0.93V = 119.05

V = 128.01L

Therefore, the volume occupied by 10 moles of hydrogen gas at 145K and 705 Torr is 128.01L.

Explanation:

The biome which comprises most of Antarctica is the cold desert or polar desert.

This is defined as an area which is classified according to the species that live there.

The climate of Antarctica is very cold  with very little life forms which is why it is referred to as a cold desert or polar desert.

Answer:

The balanced equation is: H2 (g) +Cl2 (g) →2HCl (g)

Explanation:

Balancing chemical equation refers to balancing the stoichiometric coefficients on the reactants and products side. This must be done as the chemical equation obeys the law of conservation of mass and momentum.

The representation of a chemical reaction in the form of substances is known as a chemical equation. The equation in which the number of atoms of all the molecules is equal on both sides of the equation is known as a balanced chemical equation. The Law of conservation of mass governs the balancing of a chemical equation.

Given chemical equation

The balanced chemical equation for the hydrogen + chlorine -> Hydrogen Chloride.

H2 + Cl2 → 2HCl

The equation is balanced as on the reactants side there are two hydrogens present and the same on the products side. For chlorine as well the same thing goes two chlorine atoms on the reactants side and two on the products side.

Answer:

There is no net loss of energy from the collisions.

Explanation:

Gas particles are constantly colliding with each other and the walls of their container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container.

Diagram Z

Explanation:

A cell placed into a hypotonic solution will swell and expand until it eventually burst through a process known as cytolysis.

Answer:

Diagram Y

Explanation:

Osmosis is the passive movement of water molecules across (into or out of) a cell membrane. "Passive" means that the process occurs automatically without the need for chemical energy.

In the diagrams above, a plant cell is shown as it would appear in a solution with a solute concentration more than its own (X), a solution with a solute concentration equal to its own (Y), and a solution with a solute concentration less than it own (Z). The movement of water is toward the area of more solute concentration (and therefore less water concentration).

The answer, then, is Diagram Y.

Answer:

A high pressure area is an area where the air sinks. As it does, it warms up by the adiabatic effect of a greater pressure and that causes the clouds to evaporate, giving place to a clear sky

Explanation:

A high-stress area, high, or anticyclone, is a location in which the atmospheric stress on the surface of the planet is more than its surrounding environment.

In a high-Pressure system, it has better pressure in its center than in the regions around it. Winds blow away from excessive pressure.

Swirling withinside the contrary route from a low-stress system, the winds of an excessive pressure system rotates clockwise north of the equator and counterclockwise south of the equator.

Hence, these are the characteristics of high-pressure system.

Answer:

Partial pressure of carbon dioxide is high in the pulmonary capillaries.

Explanation:

Answer:

≈32°C

Explanation:

1) the rule:

[tex]\frac{pV}{T}=const;[/tex]

2) according to the rule above the final temperature can be calculated as:

[tex]t_{final}=\frac{p_{init}}{p_{final}}*t_{init}; \ = > \ t_{final}=\frac{100}{300}*95=32.[/tex]

According to the Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.

Gay-Lussac's law is defined as a gas law which states that the pressure which is exerted by the gas directly varies with its temperature and at a constant volume.The law was proposed by Joseph Gay-Lussac in the year 1808.

The pressure of the gas at constant volume reduces constantly as it is cooled till it undergoes condensation .The law is given by the formula, V₁/T₁=V₂/T₂, which on substitution gives T₂=95×100/300=31.6 °C.The container in Gay-Lussac's law is considered to be rigid  in contrast to the container present in Charle's law.

Thus, as per  Gay-Lussac's law, as volume is constant the temperature must be decreased to 31.6°C.
