The equilibrium constant is a quantity which characterizes an equilibrium in a reaction .

Explanation:

  • The equilibrium constant is a quantity which characterizes an equilibrium in a reaction
  • it is based on the final concentrations of involved compounds.
  • The value is constant for  all of the experiments .
  • It should be consistent because this  constant is defined to be the relation between all concentrations of involved compounds at chemical equilibrium.

If the motor M rotates in the direction shown by the arrow as illustrated in the diagram below, what is going on? A. 1 and 2 are
madreJ [45]

Answer:

C. 1 and 2 are going up

Explanation:

The motor turns counterclockwise, so the pulley above it will also turn counterclockwise.  This means the pulley to the right will turn counterclockwise.  So block 2 will move up.

Since the belt is twisted on the left side, the pulley on the left will spin in the opposite direction (clockwise).  So block 1 will also move up.

one car accelerates at half the rate of another how much longer does it take the first car to travel a quarter mile
Orlov [11]

Answer:

t=1/4v1

Explanation:

Given data

Car one

Speed =v1

Time =t

Distance =1/4 mile

Given data

Car two

Speed =v1/2

Time =t

Distance =d

Speed =distance/time

v1=1/4/t

v1t=1/4

t=1/4*1/v1

t=1/4v1 seconds

The leaves of a tree lose water to the atmosphere via the process of transpiration. A particular tree loses water at the rate of
Gnoma [55]

Answer:

The speed of the sap flowing in the vessel is 1.90 mm/s

Explanation:

Given:

The rate of water loss, Q = 3 × 10 ⁻⁸ m³/s

Number of vessels contained, n = 2000

Diameter of the vessel, D = 100 Mu m

thus, the radius of the vessel, r = 50 × 10⁻⁶ m

Now, the rate of flow is given as:

Q = AV    .............(1)

where, A is the area of the cross-section

V is the velocity

Total area, A = n × (πr²)

substituting the values in the equation (1), we get

3 × 10 ⁻⁸ m³/s = [2000 × (π × (50 × 10⁻⁶)²)] × V

or

V = 1.909 × 10⁻³ m/s or 1.90 mm/s

Hence, the speed of the sap flowing in the vessel is 1.90 mm/s
