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:

See Explanation.

Explanation:

Element Name: Neon (check a periodic table)

Atomic Number: 10 (number of protons)

Atomic Mass: 20 (number of protons + number of neutrons [electrons have negligible mass])

Protons: 10 (P in the black circle)

Electrons: 10 (number of red dots)

Neutrons: 10 (N in the black circle)

Valence Electrons: 8 (number of red dots on the outermost ring)

Answer:

Violet

Explanation:

It has the shortest wavelength and therefore the highest frequency.

Answer:

Make them all gather up at the core of the Earth so it will attract everything towards it and practically just condense the planet.

But why are you even planning to do that? :/

Answer:

Matter is anything that has mass and occupies space.

Explanation:

Sodium is a highly reactive metal since it has 1 valence electron, while Iodine is a less reactive non metal with 7 valence electrons.

Answer:

Like other alkali metals, rubidium metal reacts violently with water. As with potassium (which is slightly less reactive) and caesium (which is slightly more reactive), this reaction is usually vigorous enough to ignite the hydrogen gas it produces.

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:

S+O2⇒SO2

Explanation:

Answer:

The balanced equation is S + O2 → SO2

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:

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

Answer:

the woman

Explanation:

Group 1 of the periodic table consists of hydrogen and the alkali metals. ...

Group 2 consists of the alkaline Earth metals. ...

Groups 3–12 contain transition metals. ...

Groups 13–16 each contain at least one metalloid. ...

Group 17 contains halogens. ...

Group 18 consists of noble gases.

Answer:

Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.

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:

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:

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.
