[2015] Justin Liu: Reactions

And im the Element Name

Hiya!Im the Atomic NumberI also tell you the # of protons

Im the Element Symbol

Hi!My name's the Atomic Mass

Isotopes:atoms that have the same # of protons but different # of neutrons.(different mass)

Intramolecular forces:an attractive force between atoms and ions within a compound- Ionic/ Hydrogen Bonding- Dipole-dipole- London dispersionIntermolecular forces:an attractive force between molecules

Metal + Non-metal → IonicNon-metal + Non-metal → CovalentNon-metal oxide + Water → AcidMetl oxide + Water → Base

Decomposition Reaction AB → A + B

Synthesis Reaction A + B → AB

Hydrate → water + ionic compoundMetal Nitrate → metal nitrite + oxygen →Metal Carbonate → metal oxide + carbon dioxideMetal Hydroxide → Metal oxide + water

Complete reactionCxHy + O2 → CO2 (g) + H2O (g)Incomplete reactionCxHy + O2 → CO2 (g) + H2O (g) + CO (g) + C (s)

Combustion Reaction

Single Displacement AB + CD → AD + CB

Double Displacement AB + CD → AD + CB

Dalton's Law

Steps for Solving Gas Stoichiometry Problems1. Write a balanced equation for the reaction2. Write the given information under the appropriate reactants and products. Put a question mark under the reactant or product for which information is needed.3. Convert all amounts to moles4. Compare molar amounts using stoichiometry ratios from the balanced equation. Solve for the unknown molar amount.5. Convert the new molar amount into the units required. You may multiply by a conversion factor, or use a set of conditions with the ideal gas law, PV=nRT
