The average distance of the planet mercury from the sun is 0.39 times the average distance of the earth from the sun. How long i

Stels [109]

Answer:

$T_1=0.24y$

Explanation:

Using Kepler's third law, we can relate the orbital periods of the planets and their average distances from the Sun, as follows:

$(\frac{T_1}{T_2})^2=(\frac{D_1}{D_2})^3$

Where $T_1$ and $T_2$ are the orbital periods of Mercury and Earth respectively. We have $D_1=0.39D_2$ and $T_2=1y$ . Replacing this and solving for

$T_1^2=T_2^2(\frac{D_1}{D_2})^3\\T_1^2=(1y)^2(\frac{0.39D_2}{D_2})^3\\T_1^2=1y^2(0.39)^3\\T_1^2=0.059319y^2\\T_1=0.24y$

How many carbon atoms are there in 5 molecules of CHCl3?

lukranit [14]

There are 5 carbon atoms present in the Chemical formula, $CHCl_\\{3}$ .

<h3>What is a chemical formula?</h3>

A chemical formula is used to show the number and type of atoms present in a molecule, using the atomic symbols of the elements and numerical subscripts.

From the chemical formula;

We can deduce that we have the following elements and their corresponding number of atoms in one molecule of the compound;

Carbon = 1 atom

Hydrogen = 1 atom

Chlorine = 3 atoms

So, in 5 molecules of the compound;

Carbon = 1 x 5 = 5 atoms

Hydrogen = 1 x 5 = atoms

Chlorine = 3 x 5 atoms = 15 atoms

In conclusion, from the solution above, we can say that we have 5 atoms of carbon present in 5 molecules of $CHCl_3$ .
