The question correctly reads:

The reaction between nitrogen and hydrogen to produce ammonia is described as an equilibrium reaction. What substances are present in the reaction mixture when equilibrium has been obtained?

3H2 + N2 = 2NH3

N2

H2

NH4+

NH3

Answer:

N2,H2,NH3

Explanation:

Equilibrium is said to be attained when the rate of forward reaction equals the rate of reverse reaction. That is forward and reverse reactions occur at the same rate. The rate at which reactants are reformed, is the same rate at which products are formed. Hence at equilibrium both reactants and products are present in the reaction mixture. This implies that nitrogen, hydrogen and ammonia are all present in the reaction mixture at equilibrium.

ira [324]

Answer:

n=N/NA

n= 3.754×10²³/6.02×10²³

n= 6.24 s

Explanation

since there is number of molecules, make use of Avogadro's constant to get number of moles.

An acid solution is 0.100 M in HCl and 0.210 M in H2SO4. What volume of a 0.150 M solution of KOH must be added to 500.0 mL of t
Dmitry_Shevchenko [17]

Answer:

When we add 0.33L of KOH only the HCl solution will be neutralized. When we add <u>1.4 L</u> of KOH, all of the acid (the HCl and H2SO4 solution) will be neutralized.

Explanation:

<u>Step 1:</u> Data given

The solution has 0.100 M HCl and 0.210 M H2SO4

Molarity KOH = 0.150 M

Volume of acid solution = 500 mL = 0.5 L

<u>Step 2: </u>Calculate moles of HCl

Moles HCl = Molarity HCl * volume

Moles HCl = 0.100 M * 0.5 L

Moles HCl = 0.05 moles

<u>Step 3:</u> Calculate moles of H2SO4

Moles H2SO4 = 0.210 M * 0.5 L

Moles H2SO4 = 0.105 moles

<u>Step 4:</u> The balanced neutralization reaction of KOH with HCl can be written as:

KOH + HCl → KCl + H2O

The mole ratio is 1:1

This means to neutralize 0.05 moles HCl, we need 0.05 moles KOH

<u>Step 5:</u> The balanced neutralization reaction of KOH with H2SO4 can be written as:

2KOH + H2SO4 → K2SO4 + 2H2O

The mole ratio KOH: H2SO4 is 2:1

This means to neutralize 0.105 moles H2SO4 we need 0.210 moles KOH

<u>Step 6: </u>Calculate volume of KOH needed to neutralize the solution

To neutralize the HCl solution: 0.05 moles / 0.150 M = 0.33 L KOH needed

To neutralize the H2SO4 solution: 0.210 moles / 0.150 M = 1.4 L KOH needed

When we add 0.33L of KOH the HCl solution will be neutralized. When we add 1.4 L of KOH the HCl and H2SO4 solution will be neutralized.

Suppose you have 1.00 l of an aqueous buffer containing 60.0 mmol acetic acid (pka = 4.76) and 40.0 mmol acetate. what volume of
butalik [34]
Required pH = 4.93
- OH⁻ from NaOH reacts with CH₃COOH giving CH₃COO⁻ and H₂O 
- Let the volume of 3.5 M NaOH be x ml
Moles of NaOH = Moles of OH⁻ = Molarity * x ml = 3.5x mmol
- The reaction table for moles is as follows:
                   CH₃COOH + OH⁻ →  CH₃COO⁻ + H₂O
Initial               60             3.5x          40
Change         -3.5x         -3.5x         +3.5x
Final            (60-3.5x)       0           (40+3.5x)
- Substitute in Henderson equation and solve for x:
pH = pKa + log \frac{[CH_{3}COO^-]}{[CH_3COOH]}
4.93 = 4.76 + log \frac{(40+3.5x)}{(60-3.5x)}
0.17 = log \frac{(40+3.5x)}{(60-3.5x)}
\frac{(40+3.5x)}{(60-3.5x)} = 1.479
x = 5.62 ml NaOH required

What does LeChatelier's Principle state?
marusya05 [52]

Answer:

Le Chatelier's principle is an observation about chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in order to achieve a new equilibrium state.
