if you are talking about the climate change of today as in the heat your answer would be ,because the green house gases are trapping in the heat and reflecting it back down it disrupts the temperature everywhere. so the hot weather will become even HOTTER the cold weather will become warmer of come to late ,and the places such as Greenland and Antarctica which are covered in snow will start to melt making the whole globe more hot year by year

How would you describe the solid-state in terms of motion (ability to move in the space and speed) and distance between molecule

horrorfan [7]

In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

According to the kinetic theory of matter, the molecules that compose matter are in constant random motion. The nature of this motion varies in the three states of matter which are;

Solid
Liquid and
Gas

In the solid state, the molecules do not translate, they only vibrate and rotate about their mean positions. In the liquids state, the molecules translate but they still have restricted degrees of freedom due to intermolecular interactions. In the gaseous state, the molecules are completely free because there is no intermolecular interaction between the molecules hence they translate at incredibly high velocity.

What is the empirical formula for a compound that is 83.7% carbon and 16.3% hydrogen?

zubka84 [21]

Hello!

We use the amount in grams (mass ratio) based on the composition of the elements, see: (in 100 g solution)

C: 83.7% = 83,7 g
H: 16.3% = 16.3 g

Let us use the above mentioned data (in g) and values will be converted to amount of substance (number of moles) by dividing by molecular mass (g / mol) each of the values, lets see:

$C: \dfrac{83.7\:\diagup\!\!\!\!\!g}{12\:\diagup\!\!\!\!\!g/mol} \approx 6.975\:mol$

$H: \dfrac{16.3\:\diagup\!\!\!\!\!g}{1\:\diagup\!\!\!\!\!g/mol} = 16.3\:mol$

We note that the values found above are not integers, so let's divide these values by the smallest of them, so that the proportion is not changed, let's see:

$C: \dfrac{6.975}{6.975} = 1$

$H: \dfrac{16.3}{6.975} \approx 2.3$

Note: So the ratio in the smallest whole numbers of carbon to hydrogen is 3:7, t<span>hus, the minimum or empirical formula found for the compound will be:

$\boxed{\boxed{C_3H_7}}\end{array}}\qquad\checkmark$

I hope this helps. =)

How does a magnet separate mixtures?

N76 [4]

It can only do that when one of the components of the mixture is a magnetic
material.

When you have that situation, you pass the magnet over the mixture ... shaking
the mixture if it's a dry mixture of powders or pieces ... and the magnetic part of
the mixture moves toward the magnet, while the nonmagnetic parts of the mixture
couldn't care less about the magnet and they just stay where they are.
