6 moles

8 moles

9 moles

12 moles

Correct Answer: A

Solution:

According to the stoichiometry, 2 moles of

A

react with 1 mole of

B

to produce 3 moles of

C

. Since

A

is the limiting reagent, 4 moles of

A

will produce

\frac{3}{2} \times 4 = 6

moles of

C

Q2.

In a C++ program, what will be the output of the following code snippet?

#include <iostream>
using namespace std;
int main() {
    int a = 5, b = 10;
    cout << (a > b ? a : b) << endl;
    return 0;
}

Correct Answer: B

Solution:

The ternary operator evaluates the condition (a > b). Since 5 is not greater than 10, it returns the value of b, which is 10.

Correct Answer: B

Solution:

To solve for

x

, add 5 to both sides to get

3x = 21

. Then divide by 3 to find

x = 7

Elizabeth Bennet

Mr. Darcy

Mr. Collins

Lady Catherine de Bourgh

Correct Answer: B

Solution:

Mr. Darcy's transformation from a proud and aloof gentleman to a more humble and considerate person is central to the theme of overcoming pride and prejudice.

Correct Answer: B

Solution:

Subtract 3 from both sides to get

2x = 4

, then divide by 2 to find

x = 2

-2

Correct Answer: C

Solution:

The determinant of matrix

A

is calculated as

\det(A) = (2)(5) - (3)(4) = 10 - 12 = -2

Increase in renewable energy investments

Decrease in fossil fuel consumption

Higher costs for carbon-intensive industries

All of the above

Correct Answer: D

Solution:

A carbon tax is designed to reduce carbon emissions by making it more expensive to emit carbon. This can lead to increased investments in renewable energy, a decrease in fossil fuel consumption, and higher costs for carbon-intensive industries, making option 'd' correct.

His pride in his social status

His fear of rejection

His lack of financial resources

His previous engagement to another woman

Correct Answer: A

Solution:

Mr. Darcy's initial reluctance is primarily due to his pride in his social status and the perceived inferiority of Elizabeth's family.

4 A

6 A

2 A

8 A

Correct Answer: A

Solution:

The total resistance

R_t

for resistors in parallel is given by

\frac{1}{R_t} = \frac{1}{R_1} + \frac{1}{R_2}

. Substituting the values,

\frac{1}{R_t} = \frac{1}{3} + \frac{1}{6} = \frac{1}{2}

, thus

R_t = 2\, \Omega

. The total current

I

is given by Ohm's Law,

I = \frac{V}{R_t} = \frac{12}{2} = 6\, A

Correct Answer: B

Solution:

Subtract 3 from both sides to get

2y = 8

. Then divide by 2 to find

y = 4

4 atm

6 atm

8 atm

10 atm

Correct Answer: B

Solution:

Initially, the total pressure is 4 atm (from

A

) + 2 atm (from

B

) = 6 atm. Since the reaction goes to completion, all

A

and

B

are converted to

C

. The total moles of gas remain the same (2 moles of

A

+ 1 mole of

B

= 2 moles of

C

), so the total pressure remains 6 atm.

2 Ω

4 Ω

8 Ω

10 Ω

Correct Answer: C

Solution:

Using Ohm's Law,

V = IR

, the total resistance

R_{total} = \frac{24}{2} = 12

Ω. The known resistor is 4 Ω, so

R = 12 - 4 = 8

Ω.

Correct Answer: B

Solution:

The value of

\cos(0^\circ)

is 1.

2 atm

4 atm

6 atm

8 atm

Correct Answer: A

Solution:

The total pressure at equilibrium can be calculated by considering the change in moles. Initially, there are 3 moles of

X

and 2 moles of

Y

, totaling 5 moles. The reaction converts these into 1 mole of

Z

. Therefore, the total pressure at equilibrium is 1/5 of the initial total pressure (6 atm + 4 atm = 10 atm), which is 2 atm.

Correct Answer: A

Solution:

To solve for

x

, subtract 3 from both sides:

2x = 8

. Then divide by 2:

x = 4

Solution:

In a full binary tree, the number of total nodes

N

is given by

N = 2L - 1

, where

L

is the number of leaf nodes. Here,

, so

N = 2(15) - 1 = 31

2 m/s²

4 m/s²

6 m/s²

12 m/s²

v(t) = \frac{dx}{dt} = 6t - 2

. Second derivative:

a(t) = \frac{d^2x}{dt^2} = 6

. Therefore, the acceleration at

t = 2

is 6 m/s².

Correct Answer: A

Solution:

The reaction requires 2 moles of

X

for every 3 moles of

Y

. Starting with 4 moles of

X

, you can use up to 6 moles of

Y

(as 2 moles of

X

react with 3 moles of

Y

). Thus, the limiting reactant is

X

, and the maximum moles of

Z

produced is 2.

Correct Answer: A

Solution:

Substitute

x = 1

into the function:

f(1) = 2(1)^2 + 3(1) + 1 = 2 + 3 + 1 = 6
