Answer:

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

Explanation:

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.

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:22.37 mph

Explanation:

100 meters = 0.062137 miles

Assume constant speed over the distance.

0.062137 miles in 10 sec

0.372822 miles in 60 sec = 1 minute

22.36932 miles in 60 minutes

22.37 mph rounded to 2 decimals

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.

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

The number of atoms in one mole of Calcium and one mole of Carbon Dioxide is the same.

The number of atoms is determined by Avogadro's number (a constant number that determines the atoms per mole).

Avogadro's number is equivalent to 6.02 x 10²³ atoms.

This means one mole of each element contains 6.02 x 10²³. However, this number of atoms changes according to the amount of the substances or moles.

How many atoms does 1 mole of Calcium and 1 mole of Carbon Dioxide contain?

Considering these are two different substances but the number of moles is the same (1 mole each) the number of atoms is equal to Avogadro's number or 6.02 x 10²³ atom.

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.
