<em>Question:</em>
<h2>How many grams are in 2 moles of H₂O?</h2><h2 />
<u><em>Answer:</em></u>
<h3>One mole of H2O has a mass of (2*1 + 1*16 = 18g). We read the 1 and the 16 from the periodic table of the elements under “atomic weight” or “atomic mass”. I’ve taken the whole numbers from memory to keep it simple but you can read a more accurate value if you need a more accurate value from your periodic table.
</h3><h3 /><h3>So if one mole of H2O has a mass of 18g, then 2 moles will have a mass of 18*2 = 36g.</h3><h3 />

<span>The answer is false. Transverse waves are waves that oscillate perpendicular to the direction of the wave. Examples of transverse waves is that of electromagnetic radiation and seismic S waves. The other type of wave is longitudinal waves that oscillates in the same plane as the direction of the wave. An example, of longitudinal waves, is sound waves and seismic P-waves</span>
Halogens
Explanation:
Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.
- Halogens have a seven electrons in their outermost shell.
- To complete the number of electrons in this shell, they need to gain an additional electron.
- One more electron makes the halogen similar to the corresponding noble gas which is very stable.
- Halogens are very reactive groups of elements and are highly electronegative.
- They have a high affinity for electrons.
- These elements are fluorine, chlorine, bromine, iodine and Astatine.
