Answer:

gas to liquid is condensation

liquid to solid is freezing

solid to liquid is melting

gas to solid is deposition

In order for a substance to be an effective mobile phase in a chromatography experiment, it must be able to move different components of a mixture at different rates.

Chromatography involves the separation of substances using the application of the solubility differences in them. It has two phases known as the stationary and mobile phases.

The mobile phase involves motion which is why the ability of substances to move at different rates is a great factor in this type of phase. The Stationary phase on the other hand doesn't involve movement of substances.

Answer:

Because alkenes are hydrocarbons with at least one carbon-carbon double bond the alkene homologous series starts at ethene C2H4.

Explanation:

Answer:

Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen. The atoms of an organic molecule are typically organized around chains of carbon atoms. Inorganic compounds make up 1%–1.5% of a living cell's mass.

Answer:

They are made up of only one type of element, which is carbon, and therefore would fail to be categorized as an organic compound since they are not, in the first place,a compound, but a pure element.

Answer:The earths plates shifting

Explanation: The movement releases stored-up 'elastic strain' energy in the form of seismic waves, which propagate through the Earth and cause the ground surface to shake.

Answer:

As light initially enters the water, it is refracted as in figure (b) and then reflected off the mirror (at the bottom of the glass). Upon exiting the water, the light is bent away from the normal as it passes from water (more dense) and into air (less dense).

Answer:

Matter is anything that has mass and occupies space.

Answer:

To dissolve an ionic compound

Explanation:

the water molecules must be able to stabilize the ions that result from breaking the ionic bond. They do this by hydrating the ions. Water is a polar molecule. ... When you place an ionic substance in water, the water molecules attract the positive and negative ions from the crystal.

Answer:

The youngest rock layers are at the top and the oldest are at the bottom, which is described by the law of superposition.

Answer:

If a gas contracts by 1/273 of its volume for each degree of cooling, it should contract to zero volume at a temperature of –273°C; this is the lowest possible temperature in the universe, known as absolute zero.It appeared that an “ideal gas” at constant pressure would reach zero volume at what is now called the absolute zero of temperature. Any real gas actually condenses to a liquid or a solid at some temperature higher than absolute zero. Therefore, the ideal gas law is only an approximation to real gas behaviour.
