State the law of Dulong and Petit's and explain how far it is of
use in the determination of atomic weight. The chloride of a
metal is found to contain 20.2% of the metal. The specific
heat of the metal is 0.224. The vapour density of its chloride is
133.4. Calculate the exact atomic weight of the metal and also
write down the molecular formula of its chloride.

Problem page gaseous ethane reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water . if of water is produced from the reaction of of ethane and of oxygen gas, calculate the percent yield of water. be sure your answer has the correct number of significant digits in it.

1. list three scientific reasons cockroaches may fly.

Why is the bond angle in a water molecule less than the bond angle of methane? a. the central oxygen atom in water has two lone pairs of electrons, whereas the central carbon atom in methane has no lone pairs. b. the central hydrogen atom in water has one lone pair of electrons, whereas the central carbon atom in methane has two lone pairs. c. the central oxygen atom in water has four lone pairs of electrons, whereas the central carbon atom in methane has only one lone pair. d. the central oxygen atom exerts more repulsive force on surrounding atoms than the central carbon atom in methane does. reset next
