As white light passes through a prism, the red (longer) wavelengths bend less than the blue (shorter) wavelengths, so forming the rainbow of colors. true or false?

True

Explanation:

A prism is a triangular shape object made of glass which has three flat surfaces that allows light to pass through it.

When light falls on one of the surface, The process of dispersion occurs.

As we know light is made up of seven colors, The light splits ( disperse) itself into these colors when is passes through the prism.

The red color has the maximum wavelength hence it bend less than the other colors. Hence a pattern of different colors is formed which is termed as Rainbow.

As different color has different wavelength, there bending degree is also different makes a pattern of seven colors at the end.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz

the answer is a 3.8cm
