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.
The mass % of in the mixture is <u>9.93%</u>
<h3>What are hydrocarbon?</h3>
An organic substance called a hydrocarbon is made completely of hydrogen and carbon. Group 14 hydrides include, for example, 620 hydrocarbons.
The odours of gasoline and lighter fluid serve as examples of the relatively weak or insignificant odours of hydrocarbons, which are often colourless and hydrophobic.
They can be found in a wide variety of chemical forms and phases, including gases (like methane and propane), liquids (like hexane and benzene), low melting point solids (like paraffin wax and naphthalene), and polymers (such as polyethylene and polystyrene).
In the context of the fossil fuel industries, the term "hydrocarbon" refers to petroleum, natural gas, and coal that are produced naturally, as well as to their hydrocarbon derivatives and refined forms. The primary source of energy for the entire planet is the burning of hydrocarbons.

Answer:
0.30M HOAc
Explanation:
Given 250.0ml (0.96M HOAc) => 800ml(??M HOAc)
Use the dilution equation...
(Molarity x Volume)concentrated soln = (Molarity x Volume)dilute soln
(0.96M)(250.0ml) = (Molarity diluted soln)(800ml)
Molarity diluted soln = (0.96M)(250.0ml)/(800ml) = 0.30M HOAc
