I think the correct answer from the choices listed above is option A. In the modern periodic table, elements are arranged according to increasing <span>atomic number. The atomic number represents the number of protons present for a specific atom.</span>
In the area of positive charge, neutral body gets negative charge for making a dipole whereas when negative charge bought near neutral one, it gets positive charge for the same reason.........making polarization
Answer:
H must pair with Fluorine, Oxygen, or Nitrogen
Explanation:
water has polar covalent bonds, the intermolecular forces are hydrogen bonds, London and Dipole forces
Answer:
2 moles for the first 2 questions and 100g of water
Explanation:
<u>The </u><u>emperical formula </u><u>can be </u><u>calculated </u><u>as follows:</u>
<u>mass :</u> 4.12g of N and 0.88g of H
<u>moles:</u> 4.12g/14.007 and 0.88g/1.008
<u>moles:</u> 0.294 and 0.873
<u>moles/smallest number</u>: (gives the ratio of atoms)
0.294/0.294 and 0.873/0.294
1 and 2.969
1 and 3
The simplest ratio of N : H is 1 : 3
<u>Hence the </u><u>emperical formula </u><u>is </u><u>NH3</u>
<u>Explanation:</u>
1. The emperical formula can be found by getting the <u>simplest ratio of atoms in a molecule.</u>
2. To get the simplest ratio of atoms we find out the <u>number of moles of each atoms in it.</u>
3. From the number of moles of atoms we can find the simplest ratio of each atom by dividing the <u>number of moles by the smallest number.</u>
