1. Covalent naming
2. ionic naming |
|
Definition
1. use mono, di, tri...etc and -ide for the second atom ex. N2O3 is dinitrogen trioxide
2. First ion gets name and roman numeral except for those in Group 1, 2 or if Ag(+1), Zn (+2) or Al (+3)
ex. Mg+2 is magnesium and Cu+2 is copper (II)
For the second ion, change ending to -ide of element if polyatomic then name according to oxygen. Ex. ClO3 -1 is chlorate if you add and oxygen it becomes ClO4 -1 which is perchlorate. If you take off and oxygen it is chlorite (ClO 2 -1)if you take one more off it is hypochlorate (ClO -1).
per-ate >ate>ite>hypo-ite |

Excess limiting
4Al(s)+3O2 (g)> 2Al2O3 (s) with 10g of Al and 19g of O2
1. equation
2. mols
3. product
4. limiting
5. grams |
|
Definition
1. Make sure the equation is balanced
2. find the mols for each:
10g Al x (1mol/27g)=.37 mol Al
19g O2 x (1 mol/32g)=.594 mol O2
3. Find mols of product for each reactant.
.594 mol O x (2mol Al2O3/3mol O2)=0.396 mols Al2O3
.37x (2mol Al2O3/4 mols Al)=0.186 mols Al2O3
4. the limiting reactant is the least so it is aluminum.
5.use the limiting reactant to find grams produced of product.
0.186 mols Al2O3 x (102g Al2O3/1mol)=18.97 g Al2O3 |
