P1V1=P2V2
100mL•500 mmHg=V2•1000mmHg
50000=V2•1000mmHg
50000/1000mmHg=V2
V2=50mL
Answer:
The answer is D. The rate of the forward reaction is greater than the rate of the reverse reaction.
Explanation:
The forward reaction rate was greater than the reverse reaction rate because more product is present at time 2. This is the answer from ap classroom.
Answer:
2.8 × 10² g
Explanation:
Given data
Step 1: Convert 25°C to the absolute scale
When working with gases, we have to convert the temperatures to the Kelvin scale, using the following expression.
K = °C + 273.15 = 25°C + 273.15 = 298 K
Step 2: Calculate the moles of chlorine gas
We will use the ideal gas equation.
Step 3: Calculate the mass of chlorine gas
The molar mass of Cl₂ is 70.91 g/mol. Then,
Molarity is the molar concentration of the chemical species of the solute dissolved in the solvent. The molarity of the solution when diluted is 0.0257 M.
<h3>What is the relation between molarity and dilution?</h3>
The molar concentration or the molarity of the solution is inversely proportional to the dilution. An increased dilution will decrease the molarity of the solution.
The molarity is given by:
Also, it can be shown as:
Given,
= 0.513 M
= 25 mL
= ?
= 500 mL
Substitute value in the equation as:
Therefore, 0.0257 M is the molarity after dilution.

The amount of sodium bromide that would be formed from the reaction will be 7.5524 grams
<h3>Stoichiometric calculation</h3>
Looking at the equation of the reaction:
The mole ratio of CuBr2 and NaCl is 1:2.
Mole of 16.4 grams of CuBr2 = 16.4/223.37
= 0.0734 moles
Mole of 22.7 grams of NaCl = 22.7/58.44
= 0.3884 moles
Equivalent mole of NaCl = 0.1468 moles
Thus, NaCl is in excess while CuBr2 is limiting.
Mole ratio of CuBr2 and NaBr = 1:1
Mass of 0.0734 mole NaBr = 0.0734 x 102.894
= 7.5524 grams
