Question | Answer |
---|---|

Conversion for Celsius to Fahrenheit | degrees in F-32*5/9 |

Who discovered the charge of an electron? | Robert Millikan |

The following data were collected when analyzing a compound used in dentistry to cement repaired teeth: 50.82% Zn; 16.04% P; 33.14% O What is the empirical formula of the compound? | Converting each percentage to a mass, then dividing by the molar mass of each component gives 0.7796 mol Zn, 0.5179 mol P and 2.071 mol O or converted to small whole numbers: 3 mol:2 mol:8 mol, respectively. |

Percent Yield | actual over theoretical *100 |

Molarity | M=mol/vol |

solution dilution | M_1V_1=M_2V_2 |

Gas Laws | PV=nRT |

Pressure, force, and area | P=F/A |

Charles Law | V_1/T_1=V_2/T_2 |

Avogadro's Law | V_1/n_1=V_2/n_2 |

Dalton's Law | P_total=P_a+P_b+P_c.... with P_x=n_xRT/v |

mole fraction | chi_a=mole_a/mole_total |

Pressure for a mole | P_a=chi_a*P_total |

Average Kinetic Energy | 3/2RT |

Kinetic Energy | 1/2mass*volume^2 |

Internal energy | Delta E=q(heat)+w(work) |

Heat | q=C(heat capacity)*delta T(change in temperature) |

heat with mass | q=mass*specific heat*delta T |

work | -pressure*change in volume (delta V) |

Bomb Calorimeter | C_cal * change temperature |

Enthalpy | delta H= internal energy + pressure*change in volume |

heat of the reaction | sum of the products - sum of the reactions |

frequency | frequence = speed of light/ wavelength |

energy | energy= planks * frequency energy= h*speed of light/ wavelength |
