Answer:
The answer is Bob
Explanation:
The science exist to kinds of measurements base units and derive units of measurement.
Base units are the ones that measure: length, mass, time, electric current, temperature, luminous intensity and amount of substance.
Derivative units of measurement are obtain when we combine the base units.
Know from your question
Bob measures length is a base unit
Jill measures density is a derivative unit, is the combination of mass and volumen
Kim measures mass is a base unit
Steve measures brightness is a base unit.
For the answer to the question above, well presumably because the exact concentration of the composition KMnO4 solution doesn't matter. <span>If the concentration of the KMnO4 solution is important (usually in titrations etc.) then it is not allowed to use a wet bottle. The water in the bottle will dilute the KMnO4 solution and change the concentration of the said compound.</span>
Answer:
The answer to your question is D.
Explanation:
The latitudes near the equator receives the most direct solar energy.
Hope this helps :)
<span>A compound is ''composed'' of elements. The periodic table is made up of elements. Atoms makes up elements and elements when reacted together make compounds.
Na+ and Cl- makes NACL....salt. a compound</span>
