Answer: I think the ethanol in the solute and the sucrose is the solvent. Hope this helps!
Explanation: i learned this last year I think it is right?
A solvent is a chemical that dissolves a solute to produce a uniform solution. A solute is a substance that dissolves in a solvent, resulting in a homogeneous mixture. The solute is sucrose, and the solvent is ethanol.
What is meant by solution ?A solution is a well-mixed solution in a solvent of one or more dissolved solutes. A solute is a substance that dissolves another substance, creating a continuous medium. A solute is a substance that dissolves in a solvent, resulting in a homogeneous mixture.A solution is formed when one substance dissolves or degrades into another. A solute is any substance that dissolves to form a solution. A solvent is a chemical that is used to disperse a solute. The solute in a sugar-water solution is sugar, and the solvent is water. A solution is a homogeneous mixture of two or more particles with diameters less than one Nano meter.To learn more about Solution, refer to:

A student has a sample of solid calcium. It is shiny and metallic looking. He squeezes a pipet of concentrated sulfuric acid onto the calcium. Bubbles are produced and the calcium appears to disappear. The test tube gets hot. What kind of change occurred?
Answer:
Physical change
Explanation:
There are two types of changes: physical change and chemical change. Physical change is defined as the change that changes the physical appearance of the substance and do not affcet the chemical composition of the substance whereas chemical change causes changes in the chemical composition of the susbstance.
The given example shows physical change because solid calcium undergoes sublimation. process in which a solid substance changes into gaseous phase directly without undergoing liquid phase.
Hence, the correct answer is "Physical change".

which option is an example of a physical change??
A breaking chemical bonds
B forming chemical bonds
C nuclear decay
D melting a substance
which option is an example of a chemical change
A ironing a shirt
B melting cheese
C grinding powder
D fireworks exploding
Answer:
D
Explanation:
Melting of ice is a physical change as there no new compound is forming only state is changing So Option D is correct option. For second question Option D is correct option as combustion reaction is taking place.
What is chemical change?Chemical change is a reaction in which breaking and forming of new bonds take place. One molecule completely converted to totally different molecule. The number of atoms remains same
One famous example of chemical change is the rusting of iron. The color, odor and arrangements of atoms in products are very much different from reactant. Chemical change are mostly irreversible in nature. Physical change is just opposite of chemical change. Phase change is an example of physical change.
Thus option D is correct option in both cases.

If a gold bar is 16,000 g mass and 800 cm^3 volume what is the density?
Answer:
The answer is 20 g/cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 16,000 g
volume = 800 cm³
We have
[tex]density = \frac{16000}{800} = \frac{160}{8} \\ [/tex]
We have the final answer as

Which of the following is the conjugate acid of H2P04- ?
A. HAP04
O B. PO 3-
O C. HP04-2
O D. H3PO4
Answer:
phosphoric acid H3PO4
The conjugate acid of H₂PO⁴⁻ is H₃PO₄. Therefore, option D is correct.
A conjugate acid is a species that is formed when a base accepts a proton (H⁺). It is the species that is one proton (H⁺) more acidic than the original base.
The base is the species that can accept a proton (H⁺), and the conjugate acid is the species that is formed when the base accepts the proton. The conjugate acid has one additional proton compared to the base.
Conjugate acids play an important role in acid-base reactions as they are formed when bases accept protons, and they can donate protons in subsequent reactions to regenerate the original base.
