We divide the electromagnetic spectrum into six major categories of light, listed below. rank these forms of light from left to right in order of increasing wavelength. to rank items as equivalent, overlap them.
a) radio waves,
b) infrared,
c) visible light,
d) ultraviolet,
e) x-rays,
f) gamma rays.

Explanation:

The electromagnetic spectrum shows the wavelength or frequency range of different waves starting from gamma rays to radio waves.

In the electromagnetic spectrum, gamma rays have shorter wavelength while radio wave have longest wavelength.

The correct order is as follows :

(A) Gamma rays

(B) X rays

(C) Ultraviolet

(D) Visible light

(E) Infrared waves

(F) Radio waves

So, the correct order form left to right in order of increasing wavelength is as follows :

Gamma rays < X rays < Ultraviolet < Visible Light < Infrared Waves < Radio Waves

given:

mass of na = 115 g

excess cl2

to determine:

mass of nacl produced

explanation:

given reaction is-

2na(s) + cl2(g) → 2nacl(s)

since cl2 is in excess, na will be the limiting reagent

as per the reaction stoichiometry na: nacl = 1: 1

i.e. moles of na reacted = moles of nacl formed

now, # moles of na = mass of na/atomic mass

                                  = 115 g/23 g.mol-1 = 5 moles

therefore, moles of nacl = 5

molar mass of nacl = 58 g/mol

mass of nacl = 5 moles * 58 g.mol-1 = 290 g

ans: amount of nacl produced = 290 g

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
