6. Convert the melting point of copper into centigrade temperature. Use a formula. K= C = C ° = C

7. If 502 grams of iron completely combines with 216 grams of oxygen to form rust, how many grams of rust form?

502 g g = 718 grams rust

10.Name the phase changes Solid to Gas - sublimation Liquid to Gas - vaporization Solid to Liquid - melting Gas to Solid - deposition Liquid to Solid - freezing Gas to Liquid - condensation

11. State the temperature known as standard temperature in Kelvin and in Centigrade

11. State the temperature known as standard temperature in Kelvin and in Centigrade Table A shows this. 273 Kelvin, or 0°C

12. Calculate (with a formula) the volume of 375 grams of sodium metal.

D = Mass Volume 0.97 g/cm 3 = 375 grams Volume 0.97 g/cm 3 (V) = 375 grams 0.97 g/cm 3 = 0.97 g/cm 3 V = 387 cm 3 (3 sf)
