Answer: a precipitate.
Justification:
When two liquids are mixed together, their constituents may react chemically, forming new products whose chemical properties are different from those of the original constituents of the mixtures.
Then, some of the products formed may be insoluble in the mix. In this case is when the precipitate (solid that cannot stand in the solution) will get formed.
The formation of a precipitate is a clear signal that a chemical reaction has taken place between some constituents (elements or compounds) of the mix.
One example of this situation is the combination of a solution of baking soda, NaHCO₃(aq), and a solution of calcium chloride, CaCl₂ (aq).
Those two solutions are clear, and when combined will form a solid (precipitate) which is calcium carbonate, CaCO₃ (s). The calcium carbonate precipitates because it is not soluble in the mix.
Answer:
mixture is amino acid, peptides, carbohydrates and other simple organic compounds can be separated by paper chromatography.

Answer:
The answer to your question is
4C₇H₁₇ + 45 O₂ ⇒ 28 CO₂ + 34H₂O
Explanation:
Write the equation
C₇H₁₇ + O₂ ⇒ CO₂ + H₂O
Process
1.- Check if the equation is balanced
Reactants Element Products
7 C 1
17 H 2
2 O 3
As the number of reactants and products is different, we conclude that the reaction is unbalanced.
2.- Write a coefficient "7" to CO₂ and a coefficient of 17/2 to H₂O
C₇H₁₇ + O₂ ⇒ 7CO₂ + H₂O
Reactants Element Products
7 C 7
17 H 17
2 O 51/2
3.- Write a coefficient of 45/2 to the O₂, and multiply all the equation by 2.
4C₇H₁₇ + 45 O₂ ⇒ 28 CO₂ + 34H₂O
Reactants Element Products
28 C 28
68 H 68
90 O 90
