Answer:

Following are the solution to the given question:

Explanation:

  • Its interactions among light waves as well as different media were also called light products.
  • Even before sound rays hit a medium, the light rays bounce off.
  • Even at a similar angle with which the material initially struck its medium, sunlight reflecting.
  • When the light hits a mirror at such an angle of forty degrees, everything just rebonds at an angle of 40 degrees.
  • When light waves pass via a transparent medium, those who bend as well as change their direction.
  • Light is called transparent if it can pass via an object.
  • Whenever light waves strike a platform, this is neither re-elected nor refracted, nor expected to move.
  • The light of interacts with these materials are:

Reflection Mirror:

Water glass: refractive

Dark fabricate: Absorption 

  • Sound waves and waves of water are examples of matter waves.
  • Light waves and X-rays are electromagnetic waves.
  • There is no need for sound radiation to pass through a medium/requirement to communicate with other particles to travel like waves of matter.
  • No, even though sound waves didn't reach through the space vacuum.
  • Matter waves should interact with solid, liquid, or gas particulates to travel.

The light waves pass thru the air more quickly than sound waves.

Sound waves almost always go through a metal frame.

Light waves travel faster than electrical signals even though they don't have to crash in electromagnetic waves to particles.

C

Explanation:

the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce. The circulatory system picks up oxygen in the lungs and drops it off in the tissues, then performs the reverse service for carbon dioxide.

yawa3891 [41]

Explanation: Skeletal muscle, attached to bones, is responsible for skeletal movements. The peripheral portion of the central nervous system (CNS) controls the skeletal muscles. Thus, these muscles are under conscious, or voluntary, control. The basic unit is the muscle fiber with many nuclei. These muscle fibers are striated (having transverse streaks) and each acts independently of neighboring muscle fibers.

At 25°C, the equilibrium constant Kc for the reaction in thesolvent CCl4 2BrCl <----> Br2 + Cl2 is 0.141. If the initial c
ivolga24 [154]

<u>Answer:</u> The equilibrium concentration of bromine gas is 0.00135 M

<u>Explanation:</u>

We are given:

Initial concentration of chlorine gas = 0.0300 M

Initial concentration of bromine monochlorine = 0.0200 M

For the given chemical equation:

                   2BrCl\rightleftharpoons Br_2+Cl_2

<u>Initial:</u>          0.02               0.03

<u>At eqllm:</u>    0.02-2x     x     0.03+x

The expression of K_c for above equation follows:

K_c=\frac{[Br_2]\times [Cl_2]}{[BrCl]^2}

We are given:

K_c=0.141

Putting values in above equation, we get:

0.141=\frac{x\times (0.03+x)}{(0.02-2x)^2}\\\\x=-0.96,+0.00135

Neglecting the value of x = -0.96 because, concentration cannot be negative

So, equilibrium concentration of bromine gas = x = 0.00135 M

Hence, the equilibrium concentration of bromine gas is 0.00135 M
