Neutralize it with NaOH,add water,thickener,fragrance,preservative and colour.
Benzene is more dense than ethanol. This can be determined by calculating the density of each liquid using the formula density = mass/volume. In this case, benzene's density is higher than ethanol's because for the same volume, benzene has a higher mass.
Fractional distillation in a distillation column will remove benzene from hexane. The vapor-liquid-equilibrium data indicate that depending on initial and desired concentrations, multiple theoretical stages will likely be needed. See also vapor liquid equilibrium chart for benzene and hexane.
The pros of benzene is apple and the cons of benzene is banana.
To find the amount of oxygen required for the combustion of liquid benzene, you would need to balance the combustion reaction equation for benzene. Calculate the moles of benzene from the given mass, then use the stoichiometry of the balanced equation to determine the moles of oxygen required. Finally, convert the moles of oxygen to liters using the ideal gas law.
Molarity is a concentration unit of solutions, pure benzene is not a solution so this term is meaningless for a pure liquid. In other words: Molarity of a solution is a numerical way of saying exactly how much solute is dissolved in a solvent .Molarity is equal to the moles of solute divided by the liters of solution. Molarity of a solution can be calculated by using the following formula: M= moles of solute/liters of solution
0.371
it can be prepared from using acetylene
One can test for benzene in water using methods such as gas chromatography or mass spectrometry, which can detect even trace amounts of benzene in the water sample. These methods involve extracting the benzene from the water and analyzing it to determine its concentration.
Benzene can be converted to benzaldehyde through a reaction involving oxidation using a strong oxidizing agent, such as chromic acid (H2CrO4) or potassium permanganate (KMnO4). The oxidation of benzene results in the formation of benzaldehyde.
To calculate the mass percent of benzene in the solution, we first need to convert the mole fraction of benzene to mass fraction using the molecular weights of benzene and toluene. Then, we can use the formula: Mass percent = (mass fraction of benzene / total mass of solution) x 100 Given the mole fraction of benzene as 0.40, we can use this information to determine the mass fraction and then calculate the mass percent of benzene in the solution.
To calculate the mass of benzene, use the formula: mass = volume x density. You need to know the volume of 0.1900 L of benzene at 15°C, which can be calculated using the ideal gas law or the formula for density (density = mass/volume). Once you have the volume, multiply it by the density to find the mass.
