Answer:

Synthesis reaction

Explanation:

Synthesis reaction: two or more compounds combine to form one.

A + B → C

Decomposition reaction: one compound forms two or more.

C → A + B

Single replacement reaction: an element in one compound is replaced with another element.

AB + C → AC + B

Double replacement reaction: elements in two compounds replace each other.

AB + CD → AC + BD

ElenaW [278]

Answer: (5/6) m/s

Explanation:

Distance = 100m

Time taken = 2 min

= 2 × 60 s

= 120 s

Speed = ?

Now,

Speed = distance / time taken

Speed = 100 / 120

Speed = (5/6) m/s

A single loop of area 0.193 m2 is placed perpendicular to a magnetic field of 0.374 T. The loop is rotated about an axis lying i

DENIUS [597]

Answer: The angular speed w of the loop = 181 rad/s

Explanation:

Given that;

Area A = 0.193 m2

Magnetic field B = 0.374 T

E.m.f = 9.24v

Ø = 45 degree

According to Faraday's law when the magnetic flux linking a circuit changes, an electromotive force is induced in the circuit proportional to the rate of change of the flux linkage.

Using the formula

E.m.f = NABwcosØ

Where w = angular velocity.

Let assume that N = 1 then,

9.24 = 0.193 × 0.374 × w × cos45

9.24 = 0.051w

w = 9.24/0.051

w = 181 m/s

Therefore, the angular speed w of the loop = 181 rad/s

Boltzmann’s constant is 1.38066×10−23 J/K, and the universal gas constant is 8.31451 J/K · mol. If 1.9 mol of a gas is confined

Crazy boy [7]

Answer:

The average kinetic energy of a gas molecule is 8.49 × 10⁻²¹ J

Explanation:

According to Kinetic Molecular Theory, the average kinetic energy of gas molecules is a function only of temperature and is given by the equation:

$E=\frac{3}{2}kT$

$pV=nRT;\\T=\frac{pV}{nR}$

Substituting the value of T in the kinetic energy equation:

$E=\frac{3kpV}{2nR}$

Where p is the pressure of the gas = 9 atm = 9 × 101325 pa

k is the Boltzmann’s constant = 1.38066 × 10⁻²³ J/K,

V is the volume of the gas = 7.1 L = 7.1 × 10⁻³ m³

n is the number of moles of the gas = 1.9 mol

R is the universal gas constant = 8.31451 J/K · mol.

E is the average kinetic energy of a gas molecule

Substituting values:

$E=\frac{3kpV}{2nR}=\frac{3*1.38066*10^{-23}*9*101325*7.1*10^{-3}}{2*1.9*8.31451}=8.49*10^{-21}J$

The average kinetic energy of a gas molecule is 8.49 × 10⁻²¹ J
