Answer:
The equilibrium will shift to the right.
Explanation:
- Le Châtelier's principle states that when there is an dynamic equilibrium, and this equilibrium is disturbed by an external factor, the equilibrium will be shifted in the direction that can cancel the effect of the external factor to reattain the equilibrium.
For the reaction: <em>CH₄ + NH₃ + 1.5O₂ ⇄ HCN + 3H₂O.</em>
<em></em>
Adding NH₃ to the reaction:
- Adding NH₃ will increase the concentration of the reactants side, so the reaction will be shifted to the right (products) side to suppress the increase in the concentration of NH₃.
Considering the ideal gas law, the pressure of the gas sample is 122.18 atm.
<h3>What is an ideal gas</h3>
An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.
<h3>Definition of ideal gas law</h3>
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of gases:
P×V = n×R×T
<h3>Pressure of the gas sample</h3>
In this case, you know:
- P= ?
- V= 500 mL= 0.5 L
- n= 2.50 moles
- R= 0.082

- T= 25 °C= 298 K
Replacing in the ideal gas law:
P×0.5 L = 2.50 moles ×0.082
×298 K
Solving:
P= (2.50 moles ×0.082
×298 K)÷ 0.5 L
<u><em>P= 122.18 atm</em></u>
Finally, the pressure of the gas sample is 122.18 atm.

The product of d reaction depends on d nature of the acid
Answer:
Mass of KOH = 497.78 g
Explanation:
Given data
mass of KOH = ?
number of KOH molecules = 5.34 × 10²⁴
molar mass of KOH = 56.12 g/mol
Solution
1st we find out the number of moles of KOH
<em>number of moles = number of molecules given / Avogadro number
</em>
number of moles of KOH = 5.34 × 10²⁴ / 6.022 × 10²³
number of moles of KOH = 8.87 mol
Now we find out the mass of KOH
<em>Mass of KOH = moles × molar mass</em>
Mass of KOH = 8.87 mol × 56.12 g/mol
Mass of KOH = 497.78 g
