Answer: 1123000 Joules of energy are required to vaporize 13.1 kg of lead at its normal boiling point
Explanation:
Latent heat of vaporization is the amount of heat required to convert 1 mole of liquid to gas at atmospheric pressure.
Amount of heat required to vaporize 1 mole of lead = 177.7 kJ
Molar mass of lead = 207.2 g
Mass of lead given = 1.31 kg = 1310 g (1kg=1000g)
Heat required to vaporize 207.2 of lead = 177.7 kJ
Thus Heat required to vaporize 1310 g of lead =
Thus 1123000 Joules of energy are required to vaporize 13.1 kg of lead at its normal boiling point
Since the question is incomplete the complete question is as follows:
Formalin and methanal are both synonymous with formaldehyde. True or false?
Formalin as well as methanal are the chemical terms that are used for formaldehyde. Thus, the given statement is true.
- Formalin is the trade name of formaldehyde.
- Formaldehyde (HCHO) is also called as methanal. It is an organic compound which is simplest forms of aldehyde.
- It is mainly used for manufacturing processes related to chemicals.
- Formaldehyde is produced by the vapor phase oxidation of substrate methanol.
Hence, the given statement is true formalin and methanal are called as formaldehyde.
