Is it true barium ion Games to electrons to make its valence shell full

Chemistry
1 answer:
rjkz [21]3 years ago
5 0

Answer:

It is false

Explanation:

Barium does not gain electrons to make its valences shell full. In truth, Barium loses electrons to attain a complete octet configuration of its shell.

This is because, barium is electropositive and not electronegative.

  • As with most metals, barium will prefer to lose two electrons when forming bonds.
  • The loss of two electrons makes it isoelectronic with the corresponding noble gas.

How does heat always flow or transfer between objects or places
Tanzania [10]
Heat can travel from one place to another in three ways: Conduction, Convection and Radiation. Both conduction and convection require matter to transfer heat. If there is a temperature difference between two systems heat will always find a way to transfer from the higher to lower system.

A gas expands from a volume of 2.00L at 36.0oC to a volume of 2.50 L, what is the final temperature, if the pressure is constant
lakkis [162]
We shall consider V, the volume and T, the temperature.
According to Boyle's Laws:
\frac{V1}{T1} = \frac{V2}{T2}
In our case:
\frac{2.00}{36.0} = \frac{2.50}{T2} =\ \textgreater \  T2= \frac{2.50*36.00}{2.00} = 45

Which of the following statements is TRUE?
Karo-lina-s [1.5K]

Answer:

The correct option is E.

Explanation:

Average speed of the gas molecules = v_a

v_a=\sqrt{\frac{2RT}{M}}

T = Temperature of the gas molecule

M = molar mass of gas molecule

R = gas constant

v_a\propto \frac{1}{M}

Higher the molar mass of the molecule lesser will be the speed and vice versa.

Hence, statement A is not true.

Graham's Law.

This 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}}}

Larger the molar mass that larger the molecule lessor will be the effusion and vice versa.

Hence, statement B is not true.

According to Boyle's law, pressure of the gas is inversely proportional o the volume occupied by the gas at constant temperature. And same can also be observed from ideal gas law:

PV=nRT

P=\frac{nRT}{V}

P\propto \frac{1}{V}

Higher the pressure of the gas lower will be the volume occupied by the gas and vice versa.

Hence, statement C is not true.

With rise in temperature, effusion of gas molecule increase as kinetic energy of gas molecules increases in with increase in temperature.

Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:

K=\frac{3RT}{2N_A}

where,

K = Average kinetic energy

R = Gas constant

T = Temperature of the system

N_A = Avogadro's number

K\propto T

Higher the temperature more will be kinetic energy of gas molecule more easily it will effuse.

Hence, statement D is not true.

From this we can conclude that out of five statements first 4 statements are not true which means that none of these statements are true.
