Cathode rays are a stream of negatively charged particles or electrons in vacuum tubes. They were first seen by Johann Hittorf in 1869. They are named since they are emitted by electrode or cathode. In order to release the electrons, the electrons should first be detached from the atoms of the cathode.

Answer:
Explanation:
Hello,
In this case, the chemical reaction is:
Thus, we first identify the limiting reactant by computing the yielded moles of water by both of the reactants:
In such a way, since HBr yields less water than cadmium hydroxide, we infer that HBr is the limiting one, therefore, the yielded mass of water are:
Regards.
Ba3PO4 is not neutral, it is positive. (NH4)2SO4 is neutral, the charges cancel.
Mg2OH is not neutral, it is positive. LiF2 is not neutral, it is negative. CaOH is not neutral, it is positive. The answer is (NH4)2SO4, correct ions will have a neutral charge.
Answer: The strange liquid would float to the top of a cup of water.
Explanation:
Density = Mass/Volume
Strange Liquid Density = 70g/84mL
Strange Liquid Density = 0.833g/mL
Density of water in g/mL = 1 g/mL
Strange Liquid Density < Water Density
A substance with a lower density would be suspended above a substance with a higher density.
Since the density of the strange liquid is less than that of water, it would float to the top of a cup of water.
