A group is a vertical line on the periodic table
Answer:
A) increasing dispersion interactions
Explanation:
Polarizability allows gases containing atoms or nonpolar molecules (for example, to condense. In these gases, the most important kind of interaction produces <em>dispersion forces</em>, <em>attractive forces that arise as a result of temporary dipoles induced in atoms or molecules.</em>
<em>Dispersion forces</em>, which are also called <em>London forces</em>, usually <u>increase with molar mass because molecules with larger molar mass tend to have more electrons</u>, and <u>dispersion forces increase in strength with the number of electrons</u>. Furthermore, larger molar mass often means a bigger atom whose electron distribution is more easily disturbed because the outer electrons are less tightly held by the nuclei.
Because the noble gases are all nonpolar molecules, <u>the only attractive intermolecular forces present are the dispersion forces</u>.
Answer:
2 elements.
Explanation:
N is your Nitrogen and H is your Hydrogen. Elements are just one specific kind of atom. You have two elements with names Nitrogen and Hydrogen. Therefore, you have two elements.
Answer:
If its dirty water than its good to boil the water using fire in the bottom and the water in the top and after a bit of time than it will become clean water.
Explanation:
If we use the next formula to determine this:<span>ΔQ=mcΔT
Then we can get to the result. Be</span>cause of the conservation of energy, the quantity of heat remains the same.
So what we do is:<span><span>c1</span>∗<span>m1</span>∗(<span>T1</span>−<span>T∗</span>)=<span>c2</span>∗<span>m2</span>∗(<span>T∗</span>−<span>T2</span>)</span><span>
when plugging in 0.39 for copper and 4.19 we get 29°C for the resulting temperature. I hope this can help you</span>
