4 moles of monoatomic ideal gas is compressed adiabatically causing the temperature to increase from 300 K to 400 K. Calculate the work done on the gas in units of Joules (if the answer is negative, be sure to enter a negative sign in your answer).
Answer:
the work done on the gas is 4,988.7 J.
Explanation:
Given;
number of moles of the monoatomic gas, n = 4 moles
initial temperature of the gas, T₁ = 300 K
final temperature of the gas, T₂ = 400 K
The work done on the gas is calculated as;
[tex]W = \Delta U = nC_v(T_2 -T_1)[/tex]
For monoatomic ideal gas: [tex]C_v = \frac{3}{2} R[/tex]
[tex]W = \frac{3}{2} R \times n(T_2-T_1)[/tex]
Where;
R is ideal gas constant = 8.3145 J/K.mol
[tex]W = \frac{3}{2} R \times n(T_2-T_1) \\\\W = \frac{3}{2} (8.3145) \times 4(400-300) \\\\W = \frac{3}{2} (8.3145) \times 4(100)\\\\W = 4,988.7 \ J[/tex]
Therefore, the work done on the gas is 4,988.7 J.

A helium balloon has a volume of 36 L. The pressure of the helium gas in the balloon is 132 kPa and its temperature is 27 degrees Celsius. How many moles of helium are in the balloon?
Answer:
[tex]n =1.905mol[/tex]
Explanation:
Hello!
In this case, by considering helium gas as an ideal one, we can use the following equation:
[tex]PV=nRT[/tex]
Whereas P should go in atmospheres and T in Kelvins; thus we proceed as follows:
[tex]n=\frac{PV}{RT}=\frac{132kPa*\frac{1atm}{101.325kPa}*36L}{0.08206\frac{atm*L}{mol*K}(27+273)K} =1.905mol[/tex]

A sample of 523.1 mg of impure KBr is treated with an excess of AgNO3 and 814.5 mg of AgBr is obtained. What is the purity of KBr?
Answer:
98.68%
Explanation:
Step 1: Write the balanced equation
KBr + AgNO₃ ⇒ AgBr + KNO₃
Step 2: Calculate the moles corresponding to 814.5 mg (0.8145 g) of AgBr
The molar mass of AgBr is 187.77 g/mol.
0.8145 g × 1 mol/187.77 g = 4.338 × 10⁻³ mol
Step 3: Calculate the moles of KBr needed to produce 4.338 × 10⁻³ moles of AgBr
The molar ratio of KBr to AgBr is 1:1. The moles of KBr needed are 1/1 × 4.338 × 10⁻³ mol = 4.338 × 10⁻³ mol.
Step 4: Calculate the pure mass corresponding to 4.338 × 10⁻³ moles of KBr
The molar mass of KBr is 119.00 g/mol.
4.338 × 10⁻³ mol × 119.00 g/mol = 0.5162 g
Step 5: Calculate the purity of KBr
0.5162 g of KBr are in a 0.5231 g-sample. The purity of KBr is:
P = 0.5162 g/0.5231 g × 100% = 98.68%

Explanation:
To solve this problem we'll need to keep in mind the formula for the kinetic energy of an object:
E = 0.5 * m * v²Where E is the kinetic energy, m is the object's mass and v its velocity.
We input the data given by the problem:
500000 J = 0.5 * m * (35 m/s)²And solve for m:
m = 816.33 kgTrial 12 1.Volume of Acid used ( mL) 2020 2.Molarity of acid used (M) 0.0160.016 3.Initial volume reading of base buret 018.6 4.Final volume reading of base used 18.636.9 5.Volume of base used (4-3, mL) _________ _________ 6.Molarity of base (1*2/5, M) _________ _________ 7.Average molarity of base _________
Answer:
[tex]V_B = 18.3mL[/tex] -- Volume of base used
[tex]M_B = 0.0175M[/tex] --- Molarity of base
Explanation:
Given
[tex]V_A = 20mL[/tex] -- Volume of acid used
[tex]V_B_1 = 18.6mL[/tex] --- Buret Initial reading
[tex]V_B_2 = 36.9mL[/tex] --- Buret Final reading
[tex]M_A = 0.016M[/tex] --- Molarity of the acid
Solving (a): Volume of base used (VB)
This is calculated by subtracting the initial reading from the final reading of the base buret.
i.e.
[tex]V_B = V_B_2 - V_B_1[/tex]
[tex]V_B = 36.9mL - 18.6mL[/tex]
[tex]V_B = 18.3mL[/tex]
Solving (b): Molarity base (MB)
This is calculated using:
[tex]M_A * V_A = M_B * V_B[/tex]
Make MB the subject
[tex]M_B = \frac{M_A * V_A }{V_B}[/tex]
This gives:
[tex]M_B = \frac{0.016M *20mL}{18.3mL}[/tex]
[tex]M_B = \frac{0.016M *20}{18.3}[/tex]
[tex]M_B = \frac{0.32M}{18.3}[/tex]
[tex]M_B = 0.0175M[/tex]
Solving (c): There is no such thing as average molarity

B)The rate-determining step of a reaction is the rate of the fastest elementary step of its mechanism.
C)Since intermediate compounds can be formed, the chemical equations for the elementary reactions in a multistep mechanism do not always have to add to give the chemical equation of the overall process.
D)In a reaction mechanism, an intermediate is identical to an activated complex.
E)all of these statements are true.
Answer:
If we know that a reaction is an elementary reaction, then we know its rate law.
Explanation:
An elementary reaction is a reaction that takes place in one reactive encounter. This means that the two species interact in a single step to give the products.
If two reactants interact in a single step to yield the products then we can easily deduce the rate law from the reaction equation.
For instance, For the reaction;
2A + B → C
The rate law is
rate = k[A]²[B].
If the reaction is an elementary reaction and the equation of the reaction is balanced, then we can deduce the rate law from the balanced reaction equation.

Gay-Lussac’s law: a, b, d, e (c is incorrect)
Boyle’s law: b, c, d, e (a is incorrect)
Answer:
DBE
Explanation:
Cause I got it right
The correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.
Charles's law states that, under the assumption of constant pressure, the volume of a gas increases or decreases with its temperature. As the temperature increases, the gas molecules move more quickly and occupy more space, increasing the volume of the gas.
Gay-Lussac's law states that, assuming a constant volume, the pressure and temperature of a gas are exactly related. Increasing temperature causes the gas molecules to become more kinetically energetic and collide with the walls of the container more frequently, increasing the pressure.
Boyle's law states that at a given temperature, the pressure and volume of a gas are inversely proportional. The reduced volume forces the gas molecules into a smaller area, increasing the chance of collisions with the container walls and pressure.
Therefore, the correct options for Charles's law, Gay-Lussac's Law and Boyle's law are D, B and E respectively.

A food company produces raspberry coulis as a topping for its best-selling line, double strength chocolate mousse pie. Fresh raspberries comprising 5% seeds, 20% pulp solids, and 75% water are homogenised and placed in a stainless steel vat. Sugar is added to give a raspberry:sugar mass ratio of 3.5:1. The mixture is blended, strained to remove the seeds, then heated to reduce the water content to 35%. Half a tonne of coulis is produced every day.
Required:
a. What mass of raspberries is required per week?
b. How much sugar is required per week?
c. What is the sugar content of the coulis?
Answer:
5357.1429kg per week
2142.8571 kg per week
Explanation:
Given that :
Fresh Raspberries :
5% = seeds
20% = pulp solids
75% = water
Raspberry : Sugar = 3.5 : 1
Water content = 35%
Coulis produced per day = 0.5 tonnes
Mass of Raspberry produced per week :
Mass is measured in kg;
1 tonne = 1000kg
0.5 tonne = (1000/2) kg = 500kg
Mass of Coulis produced per week = 500kg * 7 = 3500kg
Coulis contains 35% water, Raspberry required 75% water :
(3500 / 35) * 75 = 7500kg
Raspberry : Sugar ratio = 3.5 : 1
Mass of Raspberry :
[7500 - (1 /3.5) * 7500]
7500 - 2142.8571
= 5357.1429kg per week
