Answer:

Increase the pressure of the gas

Explanation:

According to the Pressure law, for a fixed mass of gas, at a constant volume (V), the pressure (P) is directly proportional to the absolute temperature (T).

From the kinetic molecular theory, gases are composed of particles which are in constant motion, colliding with themselves as well as with the walls of their container.

When the temperature of these gas molecules is increased, the molecules acquire more kinetic energy and the rate of collisions increases. Since the container cannot expand, the increase in pressure is due to the increase in collisions between the molecules of the gas as well as with the walls of their container.

In the Haber process, nitrogen gas is combined with hydrogen (from natural gas) to form ammonia. If ammonia is formed at 0.345 M
algol13

Answer:

r_{N_2}=-0.1725M/s

Explanation:

Hello,

In this case, by means of the law of mass action, we firstly write the described chemical reaction:

N_2(g)+3H_2(g)\rightarrow 2NH_3(g)

Thus, as ammonia is being formed at 0.345 M/s, nitrogen will be disappearing at (consider law of mass action):

r_{NH_3}=0.345M/s\\\\\frac{1}{-1} r_{N_2}=\frac{1}{-3}r_{H_2}=\frac{1}{2} r_{NH_3}\\\\r_{N_2}=-\frac{1}{2} r_{NH_3}=-\frac{1}{2} *0.345M/s\\\\r_{N_2}=-0.1725M/s

Best regards.

How many Mg atoms are present in 170g of Mg
PIT_PIT [208]
In order to calculate the number of atoms, we must first know the number of moles present. And
moles = (mass present) / (molecular mass)
Therefore, the moles of Mg present are
170 / 24 = 7.08
The number of atoms in a mole of substance is given by Avagadro's Number which is 6.02 x 10^23
Since there are 7.08 moles, there are:
7.08 * 6.02*10^23
= 4.26 * 10^24 atoms

If a wave has a wavelength of 13 meters and a period of 0.005, what's the velocity of the wave? A. 2,600 m/s B. 260 m/s C. 1,300
Rina8888 [55]

Answer:

V = 2600ms⁻¹

Explanation:

Given parameters:

Wavelength(λ) = 13meters

Period (T) = 0.005s

Period(T) is the time it takes for a full cycle of vibration to pass through. It's unit is in seconds (s)

The Velocity of waves is expressed as:

V = fλ

Where f = frequency(s⁻¹)

Frequency of a wave is the number of waves that passes through a point per unit time

f = 1/T

Where T is the period

We can therefore express Velocity of waves as a function of period

V = λ/T

Inputing the parameters, we have:

V = 13m / 0.005s

V = 2600ms⁻¹

Which statement correctly identifies the nuclide that is most likely to be unstable and describes why?
iVinArrow [24]
The answer would be B.

U-238 has a n to p ration of 1.6:1. 146 neutrons and 92 protons.

It is actually the most commonly used isotope is reactors.

C-14 is also a radioactive isotope with 8 neutrons and 6 protons.

The usual and ideal n to p ratio is 1:1 such as C-12 or Mg-24
