On a planet where the temperature is so high, the ground state of an electron in the hydrogen atom is n = 4. What is the ratio o

kvv77 [185]

Answer:

1:16

Explanation:

The ground state of an electron on the planet is n = 4 compared the ground state of an electron at n =1. For a hydrogen atom, the electron energy level is given as:

$E(n)=\frac{13.6}{n^2}\\ \\Where\ n\ is\ the\ ionization \ energy$

$E(4)=\frac{13.6}{4^2}=\frac{13.6}{16}\\ \\E(1)=\frac{13.6}{1^2}=\frac{13.6}{1}\\ \\The\ ratio\ of\ their\ ionization\ energy=\frac{E(4)}{E(1)} =\frac{\frac{13.6}{16} }{\frac{13.6}{1} } =\frac{1}{16}=1:16$

Hence the ratio of their ionization energies is 1:16

What kind of reaction does Iron (III) and copper (II) sulfate solution produce?

ivanzaharov [21]

Answer:

The answer to your question is Single replacement

Explanation:

Types of reaction in Chemistry

Synthesis two or more reactants combine to produce one single product

Decomposition one reactant splits producing two or more products

Single replacement One element replaces a similar one in a compound.

Double replacement Two compounds interchange their cations and anions.

Combustion one compound reacts with oxygen to produce carbon dioxide and water.

Reaction given

Fe⁺² + CuSO₄ ⇒ Cu + FeSO₄

This is a single replacement reaction

3. Plasma

- indefinite shape & volume

- affected by magnetic and electric field

- drift and flow freely

4. Liquids have fixed volume meaning packed tighter together as gases do not have fixed shape or volume .

D would be correct
