Using a volumetric flask, an electronic balance, some water and some store-bought salt (NaCl), make up some 0.40 M solution and have it looked at by the instructor. Show calculations and explain how you made it:​

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Geothermal energy for industrial use is available almost anywhere. a. true b. false
