16
Q

What elements make up organic matter?

A

Carbon (C) and Hydrogen (H) (nitrogen is also important)

17
Q

Isotope

A

Same number of protons, different number of nuetrons

18
Q

Ionic bond

A

TRANSFER metal (lose) and nonmetal (gain) to become a salt/crystal (becomes atoms with opposite charges that are attracted to each other and easier to break than covalent)

19
Q

Oxidation

A

A metal atom that loses electrons (LEO says GER)

20
Q

Reduction

A

A nonmetal atom that gains electrons (LEO says GER)

21
Q

Covalent bond

A

SHARE nonmetal+nonmetal/molecules/shown with line which represents a pair of 2 electrons/harder to break than an ionic bond

22
Q

The # of covalent bonds an atom can form is the..

A

of valence electrons needed to fill outer shell (H can form 1, O can form 2, etc) maximum 3 bonds between 2 elements but can form bonds with other elements if it needs more

23
Q

Polar covalent bond

A

Atoms that do not exert the same pull on shared electrons/The stronger atom ends up with a slight negative charge (more electrons on that side)

24
Q

Nonpolar covent bond

A

No difference in charge between the two ends of bonds (diatomic N2, O2 etc)

25
Q

Mixture

A

Not chemically combine ex salt water

26
Q

Diatomic Molecules

A

2 of the same element (O2, N2, H2, Cl2)

27
Q

Substance

A

Chemically combined

28
Q

Acids

A

Form hydrogen ions (H+) in solution…

HCl hydrochloride acid dissolves in H+ and Cl-/less than 7 pH/Electrolyte

29
Q

Electrolytes/ types of Electrolytes

A

Free moving ions in a mixture that conducts electricity. Aqueous salts (NaCl MaCl) and Acids (HCl HNo) and Bases (NaOH)

30
Q

Aqueous Salts

A

Breaks up, Cl- attracts to H+ and Na+ attracts to O-,

31
Q

As water cools, hydrogen bonds..

A

Form and release energy to moderate temp

32
Q

As water heats, hydrogen bonds..

A

Break and absorb energy to moderate temp

33
Q

Ph Scale

A

Measures the hydrogen ion (H+) concentratin

0(most acidic)–7(nuetral)–> 14(basic)

34
Q

Hydrogen bonds form intermolecular attraction when?

A

(O-) is attracted to (H+) causing cohesion, adhesion, and capillary action

35
Q

Bases

A

Any compound that produces hydroxide ions (OH-) when dissolved in water…
NaOH sodium hydroxide dissolves into Na+ and OH-/Electrolyte

36
Q

Neutralization

A

The Ph level is returned to 7 when the H+ from the acid combines with the OH- from the base forming H2O
