Yes, alcohol burns off when cooking. To make sure that alcohol cooks out completely, you need to cook the food longer. The possible situation for alcohol in recipes is fermentation.
Foods undergo fermentation process for saving and storing them for longer periods through preservation.
In general, alcohol is used during fermentation process to increase their storage time.
During fermentation, food is cooked for about 15 minutes. That is why most foods contain almost 40 percent of alcohol in them.
In order to remove alcohol, it is necessary to cook food longer. The longer you cook, the more alcohol cooks out.
However, to remove all traces of alcohol, make sure to cook food for about three hours.

This is a synthesis reaction we're given that aluminium (Al) can react with oxygen gas (O2 to produce aluminium oxide (Al2O3).The balanced chemical equation for this reaction is 4Al(s)+3O2(g)→2Al2O3(s)
When two separate atoms or molecules interact to create a new compound or molecule, the process is known as a "synthesis reaction." The majority of the time, energy is released and an exothermic reaction takes place during a synthesis reaction. An endothermic result is also conceivable, though. When sodium (Na) and chlorine (Cl) are combined, sodium chloride is created. This is an illustration of a synthesis reaction (NaCl). Al2O3 is the chemical formula for the compound of aluminium and oxygen known as aluminium oxide. It is precisely referred to as aluminum(III) oxide and is the most prevalent of various aluminum oxides. Aluminum oxide is utilized for its strength and hardness.

1.00 L aqueous solution containe nod 5.80 g of sodium hydroxide, NaOH. What was the pH of the solution at 25°C? (Hint: strong acid and strong base titration, use limiting reactant)
The pH of the solution is 13.16.
What is the pH of the base?We know that the pH has to do with the concertation of the hydrogen ions that we have in the solution. We have to first obtain the concentration of the hydroxide ions and then use that to obtain the pH of the solution accordingly.
Number of moles of NaOH = 5.80 g/40 g/mol = 0.145 moles
Concentration of the solution = 0.145 moles/1 L = 0.145 M
pOH = - log( 0.145 M)
= 0.84
pH = 14 - 0.84
= 13.16
We can get the pH of the solution as 13.16.

2. What substances make up water?
explain why the water strider is able to land on the surface of the water. use your knowledge of intermolecular forces and draw a particle diagram to justify your explanation
Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water.
Surface tension:
The tension of the surface film of a liquid is caused by the attraction of the particles in the surface layer by the bulk of the liquid, which tends to minimize surface area.
The force responsible for surface tension is the cohesive force that is present between the molecules of the liquid, the surface tension of water is high this is just because there is a hydrogen bond present between the molecules of water.
As we know that the legs of a water strider are long and slender, allowing the weight of the water strider's body to be distributed over a larger surface area.
Therefore the water strider can land on the surface of the water because of the surface tension of the water.

what causes the lines in these spectra? why are the colors of the lines different? suggest a reason for the observation that the spectrum of calcium is more complicated than the spectrum of hydrogen.
Transitions of electrons within atoms or ions form spectral lines at different rungs which leads to emission of lines of different colors. Spectrum of calcium is more complicated than the spectrum of hydrogen because calcium atom have more electrons than hydrogen.
What are spectral lines?A spectral line in an otherwise smooth and continuous spectral is a dark or bright line resulting from the emission or absorption of light in a narrow frequency range compared to adjacent frequencies. Spectral lines are frequently used to identify atoms and molecules.
The spectral lines arise from electron transitions within an atom or ion. As electrons move toward or away from the nucleus (or ion) of an atom, they release or absorb energy in the form of light (or other radiation).Electrons fall on the lower rung and emit light with the energy of the rung difference. This allows different atoms to emit different colors of light.Calcium has a more complex spectrum.
