What is the half life of the graphed material?
daser333 [38]

Answer:

3 hours

Explanation:

To know the the correct answer to the question given above, it is important we know the definition of half-life.

The half-life of a substance is simply defined as the time taken for half the substance to decay.

Considering the diagram given above, the initial mass of the substance is 100 g.

Half of the initial mass = 100 / 2 = 50 g

Now, we shall determine the time from the graph taken to get to 50 g.

Considering the diagram given above, the time taken to get to 50 g is 3 hours.

Therefore, the half-life of the material is 3 hours.

Consider the reaction between no and cl2 to form nocl: 2no(g)+cl2(g)⇌2nocl(g) a reaction mixture at a certain temperature initia
AlladinOne [14]

Answer:

Kc = 0.402.

Explanation:

  • We can calculate Kc from the relation: Kc = [NOCl]² / [NO]²[Cl₂].
  • [NOCl] = 0.30 M, [NO] = 0.65 M, and [Cl₂] = 0.53 M.
  • Now, we can get Kc:
  • Kc =  [NOCl]² / [NO]²[Cl₂] = (0.30 M)² / [(0.65 M)².(0.53 M)] = 0.402.

Explain the relationship between frequency, wavelength, and energy
lukranit [14]

Answer:

The energy of a wave is directly proportional to its frequency, but inversely proportional to its wavelength. In other words, the greater the energy, the larger the frequency and the shorter (smaller) the wavelength.
