The amount of energy required to remove an electron from an atom. 2 ionization energy

A bond where electrons are shared unequally, resulting in a positively charged end and a negatively charged end of the molecule, 4 polar covalent bond

The tendency of an atom to attract a pair of electrons and bond with another atom; increases from bottom-left toward top-right of the periodic table. 3. Electronegativity

A bond where electrons are shared equally, or polar bonds in the molecule cancel each other out. 5. Non polar covalent bond

Shell or energy level where electrons are found. 1. Orbital

one bottle of aspirin holds 250 tablets, each containing 150 mg of aspirin and sells for $2.95. Another bottle holds 125 tablets

AlladinOne [14]

I bottle:

250 * 150mg = 37500mg

If 37500mg ------- cost ------- $2.95
so 1mg ------- cost ------- x

x = 1mg* $2.95 / 37500mg = $7,87*10⁻⁵

II bottle

125 * 200mg = 25000mg

If 25000mg ---------- cost ---------- $3.50
so 1mg ---------- cost ---------- x

x = 1mg* $3.50 / 25000mg = $0,00014=$1,4*10⁻⁴

$7,87*10⁻⁵ < $1,4*10⁻⁴

1st bottle is better bargain cause 1mg of aspirin its cheaper than in 2nd.
