Definition
| the reaction of water with another material (The hydrolysis of nonmetal oxides produces acids). |
|
|
Term
|
Definition
| a reaction between oxygen and another element or compound that produces heat, CO2 and/or H2O |
|
|
Term
|
Definition
1)Combustion, Photosynthesis, and Respiration release CO2 into the air
2)Marine and terrestrial plants take in the CO2
3)They are consumed by marine and terrestrial animals
4)Detritus puts CO2 in the soil and sediment and they are transformed into fossil fuels
5)the cycle starts all over again |

Term
| Determining Empirical Formula From % Composition |
|
Definition
1)Assume 100g sample
2)convert to moles
3)divide by smallest # of moles
[4)multiply by a factor that results in 2 whole numbers] |

Term
| Translating empirical formula into molecular formula |
|
Definition
1)multiply the number of atoms of each element by that elements molar mass and add all resulting numbers to get the mass of the empirical formula
2)molar mass (found using mass spectrum) /mass of formula unit= multiplier to find molecular formula |

Definition
1)Get moles of C and H from CO2 and H2O assuming 1:1 ratio
2)convert to mass to get g C and g H
3)the sum of these masses is the O in the sample
4)convert to moles
5)get mole to mole ratio

Term
| Finding Limiting Reactant |
|
Definition
1)Calculate the molar masses and then calculate the moles of reactants
2)Calculate mass produced if reaction is completed. Negative Number means that can not be the LR [which ever forms smaller amount of product] |
