In the following reaction, in which direction, left or right, will the equilibrium shift if the following changes are made?

Chemistry
1 answer:
Naddika [18.5K]2 years ago

Answer:

Shifts to the left.

Shifts to the right.

Explanation:

Based on Le Châtelier's principle, when a change occurs in a system in equilibrium, the system will try to counteract the change that was made.

In the equilibrium:

2NO (g) + H₂ (g) ⇌ N₂O (g) + H₂O (g) + 36 kJ (heat)

If N₂O is added, the equilibrium shifts to the left trying to decrease the concentration of N₂O added.

If H₂ is added, the equilibrium shifts to the right trying to decrease the concentration of H₂ added

MrMuchimi

Answer:

The correct answer is electrons.

Explanation:

The electrons refer to the negatively charged constituents, which are arranged in the orbits around the nucleus of an atom. It determines all the chemical and physical characteristics of an atom except the radioactivity and mass.  It is a stable subatomic particle witnessed in all the atoms and functioning as the chief carrier of electricity in solids.

The gas in an aerosol can is at a pressure of 3.16 atm at 32.2°C. What would the gas pressure in the can be at 22.9°C?
olasank [31]

Answer:

The pressure of the gas would be 3.06 atm

Explanation:

Amonton's law states that the pressure is directly proportional to the absolute temperature of a gas under constant volume. The equation is:

P1 / T1 = P2 / T2

<em>Where P1 is the initial pressure = 3.16atm</em>

<em>T1 is initial absolute temperature = 273.15 + 32.2°C = 305.35K</em>

<em>P2 is our incognite</em>

<em>And T2 is = 273.15 + 22.9°C = 296.05K</em>

<em />

Replacing:

3.16atm / 305.35K = P2 / 296.05K

3.06 atm = P2

<h3>The pressure of the gas would be 3.06 atm</h3>

An orbital is the space occupied by a pair of electrons.<br> true or false??
Anvisha [2.4K]

Answer:

True

Explanation:

An orbital is is the space occupied by a pair of electrons. The maximum number of electrons in an orbital is 2.

The maximum number of electrons in in the orbitals are two.

For s-sublevel with one orbital we have two electrons

      p-sublevel with three orbitals we have six electrons

      d - sublevel with five orbitals we have ten electrons

     f - sublevel with seven orbitals we have fourteen electrons

Each orbital can take a maximum of two electrons.
