Answer: D
Explanation:
A has more kg/mass than B
Answer:
an ion
Explanation:
An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons. This is not a particle within an atom
Answer:
The highest molar concentration is in the solution of potassium chloride because it's the one, with the highest molar mass.
Explanation:
If we have the same mass and the same volume in all the solutes and solutions, we should know the molar mass for each, to calculate how many moles of solute are we having.
a. LiOH → 23.94 g/m
b. KCl → 74.55 g/m
c. KOH → 56.1 g/m
d. NaOH → 40 g/m
The highest molar mass is in option b. It will have the most moles.
Technetium, with atomic number (denoted Z) 43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive. The second-lightest exclusively radioactive element, promethium, has an atomic number of 61.
Lamps light up by electricity. Although, i'm sure you knew that by now. When a light bulb connects to an electric power supply, an electric current flows between the two metal contacts. As electricity flows between the wires and filament, the filament heats up. The filaments begin to emit photons, which are essentially small packets of light.
Hope this helps!
