What observation about light supported Einstein's theory?

Chemistry
1 answer:
Llana [10]3 years ago
5 0

In 1905 Albert Einstein had proposed a solution to the problem of observations made on the behaviour of light having characteristics of both wave and particle theory. From work of Plank on emission of light from hot bodies, Einstein suggested that light is composed of tiny particles called <span>photons, </span>and each photon has energy.

Light theory branches in to the physics of <span>quantum mechanics, </span>which was conceptualised in the twentieth century. Quantum mechanics deals with behaviour of nature on the atomic scale or smaller.

As a result of quantum mechanics, this gave the proof of the dual nature of light and therefore not a contradiction.

Calculate the molecular mass of carbon monoxide (CO) by adding the atomic mass of carbon (C) and the atomic mass of oxygen (O):
Bond [772]

 The   molecular   mass  of carbon monoxide (CO)  is  28 g/mol


   <u><em>calculation</em></u>

The  molecular  mass  of CO =  atomic mass  of C + atomic  mass  of O

From  periodic table the atomic  mass  of  C = 12 g/mol and for O = 16 g/mol


Therefore the molecular  mass   of Co = 12 g/mol + 16 g/mol = 28 g/mol

What is the actual amount of phosphorous in a fertilizer with a npk ratio of 15-15-20?
OLga [1]
<span>NPK ratio system is a conventional shorthand for the ratio of the nitrogen N), phosphorus (P) and potassium (K) in a fertilizer. It actually shows amount of P</span>₂O₅.
If we use 100 kg of P₂O₅:
m(P₂O₅) = 0,15 · 100 kg.
m(P₂O₅) = 15 kg.
m(P₂O₅) : M(P₂O₅) = m(P) : 2M(P).
15 kg : 142 = m(P) : 62.
m(P) = 6,55 kg.
ω(P) = 6,55 kg ÷ 100 kg · 100% = 6,55%.
