How to name binary acids (don’t contain hydrogen)
Hydro_____ic acid
How to name oxyacids (contain H, O, and another non metal)
1) name ion
XO- :hypo____ite ion
XO2: _____ite ion
XO3: ______ are ion
XO4: per____are ion
2) remove ite and add ous acid
Or
remove are and add ic acid
Stoich first 4 steps
1) write a balanced equation
2) calculate moles of first reactant by converting grams to moles
given mass( 1 mol/ periodic table mass)
3) make ice table
4) fill in zeros
O mol for initial of products
O mol for end of reactants
What is electron affinity
The degree to which an atom attracts additional electrons
Stoich steps 5-8
5) write calculated mol weight value in box of given mass, subtract the same amount below
6) calculate initial moles of 2nd reactant, below subtract the same amount
(Initial of 1st reactant)(coeff of column wanted)/(coeff of first reactant)
7) repeat step six twice to calculate moles of products
8) convert all mole values to grams
Moles(grams in period table/1mol)
Coeff don’t matter for grams but subscripts do
Ml value for dz^2
0
Ml value for dxz dyz
+ or - 1
Ml value for dxy dx^2 y^2
+ or - 2
Why don’t Be and Mg produce a flame
First two of the group, smallest so highest Zeff, valance electrons feel a stronger pull to nucleus so electron transition doesn’t happen
What are group 1 elements called and why are they very reactive
Have the lowest Zeff so easier to remove an electron
Are group 1 oxidizing or reducing agents
Reducing
Are group 2 oxidizing or reducing agents
Reducing
Which elements in groups 1 and two are the most reducing in a solid or gas state
Cs and Ba
Three uses of hydrogen
Haber process
N2(g) + 3H2(g) —-> 2NH3(g)
Hydrogenation of vegetable oil
Alternative fuel
Reactions of hydrogen with metal form what
Ionic hydrides
Reactions of hydrogen with non metals form
Covalent compounds
Two ways hydrogen can be produced
Water gas shift reaction
-reaction of steam with CO2
Balancing steps
Other elements
Carbon
Hydrogen
Oxygen
