Q

What is an Angstrom

A

And Angstrom is a unit of length measured 10 to the -10 m the Angstrom is convenient because atomic radius and the bond lanes are typically around one or three instruments.

Q

What is the formula and molecular weight

A

The chemical formula we can figure out the formula way which is a sign of the atomic plates of all the items in the mouth.

18
Q

What is the atomic mass unit

A

The atomic mass unit is the abbreviation for weight is a popular term which is also known as mass one atomic mass unit is by definition equal 1-12 the mass of an Adam of carbon 12.

19
Q

What is the molecular weight

A

The atomic mass unit may not be explicitly included when I compounds exist as a discrete molecule the term molecular weight is usually used instead of formula weight. The molecular weight is adding up all the formula weight per element in each molecule.

20
Q

What is the mole.

A

A mole is a simply a particle number of thanks like 1000 is in a group of 12 things one mole is anything contains 6.02×10 to the 23rd entities.

21
Q

How are moles calculated

A

Bulls are calculated taking the mass in grams divided by the molecular way. This is most often utilized by Avogadro’s number.

22
Q

What is Avogadro’s number

A

6.022X 10^23

23
Q

What is the composition by mass of a given molecule.

A

How this works out is that you take the empirical formula of a substance given the molecular way divided by the total weight of a molecule would give you the percentage of each Element in each molecule.

24
Q

Section 3.9 is concentration or molarity what is molarity

A

Molarity express is a concentration of a solution in terms of multiple saw you heard volume in liters of solution Mary equals number of moles of saw you divided by number of leaders of solution.

25
Q

What is the mole fraction

A

More fraction is S equals X of us or number of moles of substances saw you divided Number of moles a solution.

26
Q

Chemical equation and stoichiometric coefficients.What are they and how do they relate to the reactants on the left and the products on the right.

A

The first step is bouncing in the left side of the Arkansas to the equation to the products are the rights of your plane changes in the Uber conservation of mass given the storage your battery cushions of the reactants side to the product side balancing equations so that you have equal number of molecules per Reactant side to the product side of the Balanced equation.

27
Q

Section 3.11 stretcher metric relationships and balance reactions.

A

The first step is to turn the number of grams that are concerned by the total number of solute’s that are produced.

28
Q

3.12 limiting reagent. What is the limiting reagent?

A

The limiting reagent is the first element that we will run out of room the equation is concerned or synthesized. The limiting reagent is always a reactant.

29
Q

What are some of the notions used in chemical equation determining the phase of each element section 3.13.

A

Solid is S liquid is L gas is G aqueous is a Q.

30
Q

Section 3.1 for the oxidation states what are the three types of bonds.

A

The three types of bonds are ionic when the ionic compounds are involved in complete transfer of electrons occurs. Second is covalent the covalent bond is when there is a shared charge of the election between the two elements.

31
Q

What are the rules for assigning oxidation states. Name the first three rules of assigning oxidation states.

A

Won the oxidation state of any element is in a standard state of zero. To the sauna the oxidation states of the items in a neutral molecule must always be zero and the sum of the oxidation states of the items an ion bus always equal the ions charge. Third group one metals have a plus one oxidation state and blue to Meadows have a plus to oxidation state.

32
Q

Rules for assigning oxidation states 04 through seven

A

Step for fluorine has a negative one oxidation state. Step five hydrogen has a plus one oxidation state win bonded with something more electronegative than carbon, -1 oxidation state one bonded to an Adam less electronegative than carbon, and zero oxidation state one bonded to carbonate cell. Step six oxygen has a negative to oxidation state. And finally the worst of the halogens have a negative one oxidation state and the atoms of the oxygen family have a negative to oxidation state.

33
Q

What is the anacronym for the electronegativity of assigning oxidation states.

A

FONCIBRISCH

34
Q

Rules for assigning oxidation states rule number one.

A

The oxidation state of any almond and it’s standard state is zero.

35
Q

Rule number two oxidation state

A

Rule number two the sum of the oxidation states of an atom in neutral molecule must always be zero, and the sum of the oxidation state of the Adam is in an ion must also be equal the ions charge.

36
Q

Rule number three oxidation state

A

Group group one metals have a plus one oxidation state, and group 2 metals have a plus to oxidation state.

37
Q

Rule number four oxidation state.

A

Fluorine has a -1 oxidation state.

38
Q

Rule #5; Oxidation state.

A

Hydrogen has A plus one oxidation state when bonded to something more electronegative than carbon, a negative one oxidation state when bonded to an atom less electronegative than carbon, and a zero oxidation state when bonded to carbon.

39
Q

Will number six assigning oxidation states.

A

Oxygen oxygen has a negative to oxidation state.

40
Q

Rule number seven assigning oxidation states.

A

Rule number seven the rest of the halogens have a negative one oxidation state, and the Adams of the oxygen family have a negative to oxidation state.

41
Q

What are the common exceptions for rule number six..?

A

The common exception for real number six- hydrogen peroxide or sodium peroxide in a oxygen is in a negative one oxidation state…?
