Answer:Hope this helps!
Explanation:
You can use a flame test to help identify the composition of a sample. The test is used to identify metal ions (and certain other ions) based on the characteristic emission spectrum of the elements. The test is performed by dipping a wire or wooden splint into a sample solution or coating it with the powdered metal salt. The color of a gas flame is observed as the sample is heated. If a wooden splint is used, it's necessary to wave the sample through the flame to avoid setting the wood on fire. The color of the flame is compared against the flame colors known to be associated with the metals.
Answer: Volume = 0.01L
Explanation:
The density of a substance is given by; Density = Mass / Volume.
In this question, Mass = 1000g, Volume = ? and Density = 100 Kg/L
For the units to be uniform, we convert 1000g to Kg = 1Kg
Therefore, Volume = Mass / Density = 1Kg / 100Kg/L = 0.01L

Answer:
In this SI units system, there are seven SI base units and three supplementary units. The base SI units are metre, kilogram, second, kelvin, ampere, candela and the mole and the three supplementary SI units are radian, steradian and becquerel. All other SI units can be derived from these base units.
