Full combustion of methane yields only carbon dioxide and water. However, acetylene is one of the products of the partial oxidation (i.e. incomplete combustion) of methane. According to [1], "Acetylene may be produced from methane in any process which raises the methane to a high temperature for a very short period followed by rapid cooling. [....] The process was studied at temperatures of 1000°C to 1300°C and reaction times of .01 to .03 seconds."

Ethanol does not react with bromine.
Acetylene cannot be directly converted into ethanol through a simple chemical reaction. The synthesis of ethanol typically involves the fermentation of sugars by yeast or the hydration of ethylene. Advanced chemical processes may allow for the conversion of acetylene to ethanol, but they are complex and not practical on a small scale.
1. Extract 959,6 mL from the 99 % solution. 2. Add 40,4 mL water.
Diacetone alcohol can be prepared from ethanol by first converting ethanol to diacetone by reacting it with acetone in the presence of an acidic catalyst. Diacetone is then hydrogenated to produce diacetone alcohol.
Ethanol can be prepared from sugarcane through a process called fermentation. Sugarcane juice is first extracted, then fermented with yeast to convert the sugar into alcohol. The resulting mixture is then distilled to separate and purify the ethanol.

30 ml of ethanol to 70ml of distilled water.
150 ml ethanol to 350 ml distilled water

To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.
Diacetone alcohol can be prepared from ethanol by first converting ethanol to diacetone by reacting it with acetone in the presence of an acidic catalyst. Diacetone is then hydrogenated to produce diacetone alcohol.
To prepare a 0.2 millimolar (mM) DPPH solution in ethanol, you need to dissolve 0.2 millimoles of DPPH in a final volume of 1 liter of ethanol. First, calculate the molecular weight of DPPH (usually around 394.33 g/mol) to determine the mass needed to dissolve in ethanol. Then add this mass of DPPH to ethanol and make up the volume to 1 liter.
To prepare an ethanolic solution, simply mix ethanol (commonly known as alcohol) with a solvent such as water. The ratio of ethanol to water will determine the concentration of the solution. Be sure to measure the quantities accurately and mix well to ensure homogeneity.

Preparation of PPM level standards of ethanol in waterUse the absolute alcohol to prepare the stock solutions of known concentration say for example: 100 ml of 1 g/L of ethanol solution1 g/L is equal to 1000 mg/L which is 1000 ppm. Otherwise the concentration of the 100 ml stock solution is 1000 ppm.Next step: Perform serial dilution procedure to prepare the required ppm level of ethanol standards. For performing the serial dilution, u have to convert the weight of ethanol into volume by dividing the weight by density of ethanol. Density of ethanol = 789 kg/cu.m or 789 g/L.
