Wildlife volunteering is a broad topic and there really is something for everyone. Some projects involve really getting your hands dirty in the jungle, but if this does not sound like your thing there are also plenty of other ways to get involved.
EXPERIMENT 2: Recrystallization and Melting Point. Melting Point is: â¢a constant physical property of a solid (the temperature at which it turns to a liquid) â¢reported in the lab as a melting point range (usually 1â2 ËC wide), not as a single temperature.
After (.1) Mg was added to HCL bubbled and temp increased to 33.9. pressure- 1.86. volume- 129.9. When letting it cool back to room temp (21.5 C) the new pressure was 1.76 atm. 3. Use the ideal gas equation in the Background section of the lab manual (PV=nRT) to find the number of moles of gas produced by the reaction. The gas constant, R, is given as: R = 0.082057 (L*atm)/(K*mole) You will need to convert the temperature from Celsius to Kelvin by adding 274. 4. Use the balanced equation for the reaction to convert moles of hydrogen gas, H2, to moles of Mg consumed in the reaction. 5.
