Front 71

what is the difference b/t weight and mass and what are the SI units of each?

Back 71

Mass (Kg) is a measurement of the amount of matter something contains, while Weight (N) is the measurement of the pull of gravity on an object.

Front 72

density and specific gravity problems

Back 72

density d=m/V
specific gravity F=m*g

Front 73

How do you convert from Celsius to Kelvins?

Back 73

K = C + 273

Front 74

Celsius to F

Back 74

degree F = degree C x 1.8 + 32.

Front 75

F to Celsius

Back 75

degree C = (degree F - 32.) / 1.8

Front 76

Dalton's Atomic Theory?

Back 76

1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms.
4) A chemical reaction is a rearrangement of atoms.

Front 77

In chlorine there are two isotopes, Cl-35 and Cl-37 with approx abundances of 75% and 25% respectively.
Calculate the atomic mass?

Back 77

Atomic mass = (% of isotope A) + (% of isotope B)
= (0.75 x 35) + (0.25 x 37)
= 35.5

Front 78

What are isotopes?

Back 78

Isotopes are atoms that contain the same number of protons but a different number of neutrons.

Front 79

What are the Chalogen elements?

Back 79

From Oxygen down to polonium.

Front 80

What are covalent compounds?

Back 80

contain two nonmetallic elements

named by the first element in the formula containing a greek prefix

Front 81

Binary Acids?

Back 81

Contain only hydrogen and a nonmetal

prefix hydro- end with -ic
ex. HCl is hydrochloric acid

Front 82

Oxyacids?
what are the formulas for:
nitrate
nitric acid
nitrite
nitrous acid
perchlorate

Front 83

Dilution equation

Back 83

MV1=MV2

Front 84

what is percent purity?

Back 84

percent purity = mass/mass of whole * 100

Front 85

what is a combination reaction?

Back 85

C + O2 -> CO2

Front 86

What is a decomposition reaction?

Back 86

2KClO3 -> 2KCl + 3O2

Front 87

Sing displacement reaction

Back 87

Zn + CuSO4 -> ZnSO4 + Cu

Front 88

Disproportionaltion reaction

Back 88

a single element undergoes both oxidation and reduction simultaneously

Front 89

How do you determine the limiting reactant?

Back 89

use stoichiometry to calculate how much product is produced by each reactant. NOTE: It does not matter which product is chosen, but the same product must be used for both reactants so that the amounts can be compared. The reactant that produces the lesser amount of product is the limiting reactant

Front 90

what is an electrolyte?

Back 90

Substance that contains ions that make it conductive

Front 91

Acids and bases -> Arrhenius model?

Back 91

H+ = acid
(OH0- =base

Front 92

Acids and bases -> Bronsted-Lowry model?

Back 92

acids = proton donors
bases = proton acceptors. These definitions remove the role of solvent and allow bases like ammonia and fluoride ion to be classified as bases
