Answer:

At STP, 760mmHg or 1 atm and OK or 273 degrees celcius

Explanation:

The standard temperature and pressure is the temperature and pressure at which we have the molecules of a gas behaving as an ideal gas. At this temperature and pressure, it is expected that the gas exhibits some properties that make it behave like an ideal gas.

This temperature and pressure conform some certain properties on a gas molecule which make us say it is behaving like an ideal gas. Ordinarily at other temperatures and pressures, these properties are not obtainable

Take for instance, one mole of a gas at stp occupies a volume of 22.4L. This particular volume is not obtainable at other temperatures and pressures but at this particular temperature and pressure. One mole of a gas will occupy this said volume no matter its molar mass and constituent elements. This is because at this temperature and pressure, the gas is expected to behave like an ideal gas and thus exhibit the characteristics which are expected of an ideal gas

The given question is incomplete. The complete question is as follows.

At which temperature and pressure will a sample of neon gas behave most like an ideal gas?

Choices are as follow:

(1) 100 K and 0.25 atm

(2) 100 K and 25 atm

(3) 400 K and 0.25 atm

(4) 400 K and 25 atm

Explanation:

At low pressure and high temperature there exists no force of attraction or repulsion between the molecules of a gas. Hence, gases behave ideally at these conditions.

Whereas at low temperature there occurs a decrease in kinetic energy of gas molecules and high pressure causes the molecules to come closer to each other.

As a result, there exists force of attraction between the molecules at low temperature and high pressure and under these conditions gases are known as real gases.

For the given conditions, 400 K and 0.25 atm  depicts low pressure and high temperature.

Thus, we can conclude that at 400 K and 0.25 atm  a sample of neon gas behave most like an ideal gas.

Calculate the mass, in grams, of a single tellurium atom (mte = 127.60 amu ).
UNO [17]

1 Atomic mass unit is the mass of an atom or it caliberates mass on atomic scale. It is also expressed in dalton denoted by Da whereas Atomic mass unit is denoted by amu.

1 amu can be expressed in grams as follows:

1 amu = 1.6 * 10^-2^4 g

Mass of Te = 127.6 amu

For converting in grams,

M = (127.6 ) * 1.6 * 10^-2^4 g

M = 204.16 * 10^-2^4 g

Thus, mass of Te is 204.16 * 10^-2^4 g

Examine the scenario.
GenaCL600 [577]

Answer:

The system will try to balance the change by shifting toward the exothermic reaction, and the rate of the forward reaction will increase.

Explanation:

To balance the external cooling system has to give out heat so exothermic reaction will occur .

Consider the following reaction where Kc = 154 at 298 K.2NO(g) + Br2(g) 2NOBr(g)A reaction mixture was found to contain 4.64×10-
IgorLugansk [536]

Answer:

The reaction is not at equilibrium and reaction must run in forward direction.

Explanation:

At the given interval, concentration of NO = \frac{4.64\times 10^{-2}}{1}M=4.64\times 10^{-2}M

Concentration of Br_{2} = \frac{4.56\times 10^{-2}}{1}M=4.56\times 10^{-2}M

Concentration of NOBr = \frac{0.102}{1}M=0.102M

Reaction quotient,Q_{c} , for this reaction = \frac{[NOBr]^{2}}{[NO]^{2}[Br_{2}]}

species inside third bracket represents concentrations at the given interval.

So, Q_{c}=\frac{(0.102)^{2}}{(4.64\times 10^{-2})^{2}\times (4.56\times 10^{-2})}=106

So, the reaction is not at equilibrium.

As Q_{c}< K_{c} therefore reaction must run in forward direction to increase Q_{c} and make it equal to K_{c}.
