Answer:Bunser buner
Explanation: It is meant to heat solid and liquid substance in the lab.
Answer:
8 gram
Explanation:
in case of NaOH, normality=molarity
so normality=molarity×acidity or basicity(in case of NaOH it's 1)
then
weight of NaOH required = volume in ml × equivalent weight × normality / 1000
so
1000× 40× 0.2/1000
=8 gram

Answer: The beaker in which water level has decreased more is the one that contains pure water.
Explanation: Even when water is not heated it can evaporate, that is because molecules move at different speed and those that are closer to surface can break the gass pressure and scape as water vapor.
The movement of molecules of water can be affected by the presence of solutes (salts or other soluble compounds) and increase the evaporation temperature. For this particular case, molecules of salt atract the water molecules (remember salt has ions and water is a dipole with partial charges) and do not let the water move freely which avoid them to scape to the surface.
