What does a prism show us about what white color is made up of?

With the help of a narrow beam of light, a glass prism, and a white wall it is possible to produce the band of seven colors using white light.

Explanation: White light is called as white because it consists of seven colors. The sunlight splits into seven colors namely violet, indigo, blue, green, orange, and red.

as given the equation is

2al + 6 hcl > 2 alcl3 + 3 h2(g)

as per equation two moles of aluminum reacts with six moles of hcl to give two moles of alcl3 and three moles of hydrogen gas

given: three moles of al are present and 7 moles of hcl

for three moles of aluminum nine moles of hcl will be required

however as 7 moles of hcl are present so the limiting reagent is hcl

hcl is going to decide the number of moles of product formed

when six moles of hcl are present = 3 moles of h2 are formed

when one mole of hcl is present == 3/6 mole sof h2 will be formed

when 7 moles of hcl are present = 3 x 7/ 6 moles of h2 will be formed = 3.5 moles of h2

here are some of the ways in which chemical and nuclear reactions differ.
