Earth has one moon and mars has two moons. how many more moons are found around the outer planets than the inner planets?

2 answers:

7 0

The outer planets are <span>Jupiter, Saturn, Uranus and Neptune while the inner planets are Mercury, Venus, Earth, and Mars. The outer planets have more moons than the inner planets because these planets are much larger than the inner ones. The inner planets are terrestrial while larger ones are called gas giants, mostly made up of gas.</span>

Answer:

There are 8 planets in the solar system. 4 inner planets are Mercury, Venus, Earth and Mars.

Mercury and Venus don't have any moons. Earth has one moon. Mars has two moons.

The 4 outer planets are: Jupiter, Saturn, Uranus and Neptune.

Jupiter has 67 moons, Saturn has 62 moons, Uranus has 27 and Neptune has 14 moons.

The outer planets have about 167 more moons than inner planets. Thus, outer planets have many more moons than inner planets.

Explain how you would test the presence of oxygen and hydrogen gases.

Vedmedyk [2.9K]

Place a burning splint near the opening of a test tube. If a popping noise occurs, it's probably hydrogen. Place a glowing splint in the test tube, and if it reignites, it could be oxygen. Place a burning splint into a test tube, and if it goes out, it could be carbon dioxide.

In which state of the following compounds does nitrogen have the most positive oxidation state? group of answer choices no2 nano

Amiraneli [1.4K]

The compound nitrogen have most positive oxidation state is NO₂. The correct option is b.

<h3>What is oxidation state?</h3>

The total number of electrons gained or lost by an atom in order to form a chemical bond with another atom.

The charge on an ion is equal to the sum of the oxidation states of all the atoms in the ion. A substance's more electronegative elements are given a negative oxidation state.

A positive oxidation state is assigned to the less electronegative element.

Thus, the correct option is b, NO₂.

A chemist has a 2.0 M solution of copper (II) sulfate. Is he takes 400 mL of this solution and dilutes it with 1200 mL of water,

Ksenya-84 [330]

0.66 M is the accurate molarity of the new solution of volume of 1200 ml.

Explanation:

Data given:

molarity of copper(II) sulphate, Mconc.= 2M

volume of 2M solution taken Vconc. = 400 ml

volume taken for dilution, Vdilute = 1200 ml

molarity of the diluted solution, Mdilute =?

We will use the formula for dilution as

Mconc Vconc = Mdilute x V dilute (conc is concentrated)

putting the values in the equation:

2 x 400 = Mdilute x 1200

Mdilute = $\frac{800}{1200}$

Mdilute = 0.66 M

When the solution is diluted to the volume of 1200 ml its molarity changes to 0.66 M.
