What physical properties of nylon and leather make them good material to use for shoelaces?
The physical properties of nylon and leather that make them good materials for shoelaces is that they are both durable and flexable
What does the properties of salts are different from the properties of elements that make them mean?
[read this, if you don't think it sounds good, don't use it or if it does not make good sense do not use it but read it first . THANK YOU!] What i think the statement means by is that the properties of salts are formed when an element in the group under sodium or magnesium in the Periodic Table combines with an element under fluorine.
Why does thermocol dissolve in benzene?
Thermocol is another name for polystyrene (PS), which is a type of plastic. Benzene is an industrial solvent, and it's primary use is to make styrene. The chemical structure of benzene, a non-polar organic hydrocarbon solvent, and of PS is such that benzene will dissolve styrene and polystyrene.
What separation method do you use to separate benzene from a mixture of benzene and methyl benzene?
Fractional distillation is commonly used to separate benzene from a mixture of benzene and methyl benzene. Benzene has a lower boiling point compared to methyl benzene, allowing it to be separated by distillation based on the difference in their boiling points.
Mass percent of sol of benzene in toulene when mole fraction of benzene is 0.40?
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.
Which properties of metals make them a good choice for electrical wiring?
The property of being a good conductor of electricity is what makes certain kinds of metal a good material to use for the contacts inside a light switch. Copper and brass are used for terminals on most switches because they are good conductors of electricity.
Why is benzene in the human body?
Benzene is an organic chemical compound. Benzene is a colorless and flammable liquid with a sweet smell and a relatively high melting point. It is carcinogenic and its use as additive in gasoline is now limited, but it is an important industrial solvent and precursor in the production of drugs, plastics, synthetic rubber, and dyes.Outdoor air contains low levels of benzene from tobacco smoke, gas stations, motor vehicle exhaust, and industrial emissions. Indoor air generally contains levels of benzene higher than those in outdoor air. The benzene in indoor air comes from products that contain benzene such as glues, paints, furniture wax, and detergents. The air around hazardous waste sites or gas stations can contain higher levels of benzene than in other areas.Benzene leaks from underground storage tanks or from hazardous waste sites containing benzene can contaminate well water. People working in industries that make or use benzene may be exposed to the highest levels of it.A major source of benzene exposure is tobacco smoke.

How does benzene affect your your body?
Benzene is an aromatic hydrocarbon, and this organic compound finds use as an industrial solvent. Its widest use is as a substance from which other materials can be produced. This makes it industrial feedstock or what is called an intermediate. Benzene is used to make styrene, which is used to make polystyrene, a very common plastic. About half the benzene used by industry has this as an application. We also use some benzene in the production of a wide variety of products including detergents, dyes, explosives, pesticides, pharmaceuticals and different kinds of rubber. We derive benzene from natural hydrocarbons or synthesize it from those petrochemicals, and though it is of extreme value in industry, it must be used with care as it is a known carcinogen. Use the link below for more information about this vital industrial substance.
Why do you use semiconductor why not conductors and insulators by changing their properties?
We use semiconductors instead of conductors and insulators by changing their properties because the properties of a semiconductor lies between that of a good insulator ant that of a good conductor. Any of the materials obtained depends on the level of doping.
What is a good, hard-wearing and weatherproof tile I can use to tile my patio?
With cold winter conditions, a material you can use for your patio tiles is porcelain. Its properties make resistant to your harsh weather conditions.
The density of benzene at 15 is 0.8787 Calculate the mass of 0.1900 of benzene at this temperature?
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.
