The autoignition of both ethanol and octane occurs at 363 oC. Which gas sample contains the gas molecules that have a greater av
USPshnik [31]

Answer:

See explanation

Explanation:

At the same temperature, the average kinetic energy of gases depends on the molecular mass of the gas. Hence,  given a particular temperature, lighter molecules travel faster on the average than heavier molecules.

Considering ethanol and octane, The molar mass of ethanol is 46.07 g/mol while the molar mass of octane is 114.23 g/mol. Hence, ethanol has a greater average kinetic energy than octane at the same temperature.

In some reactions, Be behaves like a typical alkaline earth metal; in others, it does not. Complete and balance the following: (
mina [271]

The correct answer is BeCl_2(l)+2Cl^-(solvated)→BeCl_4^2-.

Evaluating be behavior to see :

how it differs from the other Group 2A (2) members.

In this reaction Be behaves like other alkaline earth metals

The complete equation can be given as

BeCl_2(l)+2Cl^-(solvated)→BeCl_4^2-

BeCl_2 tends to form a chloro bridged dimer in the vapour state, however at high temperatures of the order of 1200K, this dimer dissociates into the linear monomer.

BeCl_2 has a chain structure in its solid form. Each Be atom in this structure is surrounded by chlorine atoms, two of which are connected by conversion bonds and the remaining two by covalent coordinate connections. This chain structure is displayed.

Definite basicity of salt​
inysia [295]

Answer:

A basic salt is any salt that hydrolyzes to form a basic solution. Another definition of a basic salt would be a salt that contains amounts of both hydroxide and other anions. White lead is an example. It is basic lead carbonate, or lead carbonate hydroxide.
