Answer:
1. an apparatus or container for condensing vapor.
2.
a lens or system of lenses for collecting and directing light.
Explanation:
A hypothesis is an educated guess, most likely in an "If... and then..." statement.
So, this paper is asking you to make a hypothesis about this experiment?
So: "If this happened, then this is why." Just add in your own details. :)
The molarity of a solution : 0.4 M
<h3>Further explanation</h3>
Given
0.2 moles of Potassium Oxide
500 ml of water = 0.5 L
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Assume volume of solution = volume of water(addition of solution volume from volume Potassium Oxide is negligible
Input the value :
M = 0.2 : 0.5
M = 0.4
The units of light energy emitted by blackbody radiation is originally called as quanta. Black body radiation is a type of radiation within a boy in thermodynamic equilibrium. This is a theoretical body. In 1900, Planck proposed that light and other electromagnetic waves were emitted in discrete packets of energy which were called "quanta". This was the original unit used.
Any atom can be considered stable if it has an equal number of protons and electrons, giving it a net charge of zero. If this balance does not occur that atom is ionized.
