Allright for <span><span>H2</span>O:</span> - The central atom is? --> the oxygen atom - How many atoms are bonded to the central atom? --> 2 hydrogen atoms - How many lone pairs of electrons are on the central atom? --> O has 6 electrons and has 2 single bonds, so 2 pairs - How many single bonds are there in this molecule? --> 2 - How many multiple bonds (double and/or triple) are there in this molecule? --> none For each of your molecules, answer the following questions: 1. Determine the electronegativity between the atoms of each molecule. Electronegativity O = 3.44 Electronegativity H = 2.20 3.44-2.20=1.24, so the electronegativity between O and H = 1.24 2. Identify the bond as either ionic or covalent. Electronegativity of 0.0-1.7 = covalent Electronegativity of 1.7-3.3 = ionic So it's a covalent bond 3. State whether the molecule is polar or non polar. Electronegativity of 0.5-1.7= polar covalent 4. Identify the structure as having hydrogen bonding, dipole-dipole moments or London dispersion forces (LDF). <span><span>H2</span>O</span><span> = hydrogen bonding</span>

Is Al2O3 an acid or a base?
kirza4 [7]
 Al_2O_3 is aluminium oxide (also called aloxide, aloxite and alundum). It is neither acid nor base. It has amphoteric nature meaning it can act as an acid with bases and as a base with acids. It neutralises them to salts.

What is emission spectrum and absorption spectrum? ​
andrew-mc [135]
- emission spectrum is the amount of electromagnetic radiation of each frequency it emits when it is heated (or more generally when it is excited). When the electrons in the element are excited, they jump to higher energy levels.



- Absorption spectrum is a technique used to find out what makes up a sample of a substance – in other words, a chemical analysis.
