A substance X on heating gives B and C What is X a compound or a mixture?
It may be a compound as CaCO3 which on heating gives CaO and CO2, it may be a mixture as mixture of Naphthalene and sand which on heating gives naphthalene and sand.
What is the calorific value of naphthalene?
100mjkg1
How do you convert gross calorific value to net calorific value?
Gross calorific value may be converted to net calorific value by using the following equation- Net calorific value = Gross calorific value - (10.02 x Percent Moisture)
Friedel Crafts acylation of naphthalene depend on type of solvent used?
Friedel Crafts acylation of naphthalene
Is that naphthalene balls poison?
Naphthalene is a white solid substance with a strong smell. Poisoning from naphthalene destroys or changes red blood cells so they cannot carry oxygen. This is for information only and not for use in the treatment or management of an actual poison exposure. If you have an exposure, you should call your local emergency number (such as 911).
What is the difference between Gross heating Value and Net heating value?
The heating value isthe amount of heat produced by combustion of a unit quantity of a fuelWe differentiate between gross and net heating values:Gross (or high, upper) Heating ValueThe gross or high heating value is the amount of heat produced by the complete combustion of a unit quantity of fuel. The gross heating value is obtained whenall products of the combustion are cooled down to the temperature before the combustionthe water vapor formed during combustion is condensedNet (or lower) Heating ValueThe net or lower heating value is obtained by subtracting the latent heat of vaporization of the water vapor formed by the combustionfrom the gross or higher heating value.For further information Contact: Tauseef Awan email adress microengineer.tauseef@gmail.com mob:+92306-8859595

To separate mixture of naphthalene and ammonium chloride by sublimation?
no because both sublime on heating
What solid sublimes on heating?
Some solids are Carbon dioxide, Snow, Iodine and Naphthalene
What is the value of a gross in maths?
The value of a gross is 144
Why must you use hot water bath to melt the naphthalene instead of heating it directly over a flame?
Heating it on a flame will cause possibly dangerous vapour. Hot water avoids this.
What is gross value?
Gross Development Value is the retail or sale value of property after construction.
Name the process to separate NaCl from a solution of NaCl and water?
Naphthalene is a sublimate. A sublimate is a substance which changes directly from the solid state to the gaseous state and vice-versa. So, by utilising this property, we can separate the mixture of sodium chloride and naphthalene by heating it. The naphthalene will sublimate and we'll be left with sodium chloride.
What is gross development value?
Gross Development Value is the retail or sale value of property after construction.
