Answer:
The correct answer to the following question will be "NaCl".
Explanation:
- A solute is being known as the soluble material within a liquid or a solution. The solvent is available in larger quantities than those of the solute among fluid.
- Concentration seems to be a calculation including its quantity of solvent contained in such a liquid solution, regard to something like the solvent volume.
So that NaCl is the right answer.
Answer:
sight, smell, hearing and taste
Explanation:
answer : 14 J/mol
J/mol unit in the answers gives the hint as to what you should do which is divide the J from mol
J ÷ mol
84 ÷ 6 = 14
Answer:
This question is incomplete
Explanation:
This question is incomplete, however, there are some basic things that be used to answer the completed question on your own. Flame test is a test that is used to identify metal ions in a compound. Although, not all metal ions produce a colour in a flame test.
In a flame test, a "clean wire loop" is dipped in an unknown solid/mixture of solids, the loop where the solids must have attached to is then placed in the tip of a blue flame (perhaps of a bunsen burner). A colour change/changes is then observed during the course of this process. Some popular metal ions and there colour in flame test are listed below
Lithium ion ⇒ red
Sodium ion ⇒ yellow
Potassium ion ⇒ lilac
Calcium ion ⇒ orange-red
Barium ion ⇒ pale-green
Copper ion ⇒ blue-green
rubidium ion ⇒ red-violet
Lead ion ⇒ gray white
The number of different colours observed will ultimately determine the number of elements exposed to the flame
