Answer:

a. True

Explanation:

The bonds between atoms are called chemical bonds. These bonds act as though they were a spring holding these atoms together.

When the atoms in a given bond are compressed by decreasing their distance of separation from their equilibrium position, a force provided by the bond tries to prevent these atoms from getting too close than usual. If on the other hand the atoms are stretched by increasing their distance of separation from their equilibrium position, a force provided by the bond tries to pull these atoms together again. This behaviour of the bond is what makes it to be considered as being similar to a spring.

One problem with elimination reactions is that mixtures of products are often formed. For example, treatment of 2-bromo-2-methyl

NikAS [45]

Answer:

Structures are given below.

Explanation:

Treatment of 2-bromo-2-methylbutane with KOH in ethanol will give elimination of HBr through E2 mechanism.
H atoms adjacent to Br will be eliminated.
2-bromo-2-methylbutane has two possible adjacent H atoms that can be eliminated giving mixture of products.
Product of this elimination reaction is alkene. Here saytzeff fule is followed during elimination. So most substituted alkene will be major product.
Structure of alkenes are given below.

A gas mixture contains HBr, NO2, and C2H6 at STP.If a tiny hole is made in the container, which gas will effuse fastest?Which ga

MakcuM [25]

Explanation:

Molar mass of HBr = 81 g/mol

Molar mass of nitrogen dioxide gas = 46 g/mol

Molar mass of ethane = 30 g/mol

Graham's Law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

$\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}$

So, the gas with least molar mass will effuse out fastest from the container and that is ethane gas.

The formula for average kinetic energy is:

$K.E=\frac{3}{2}kT$

where,

k = Boltzmann’s constant = $1.38\times 10^{-23}J/K$

T = temperature = 273.15 K ( at STP)

As we can see from the formula that kinetic energy depends upon only temperature of the gas molecule.

So, from this we can say that all the gas molecules have the same average kinetic energy at this temperature.
