Answer:
Keq = 0.217
Explanation:
Let's determine the equilibrium reaction.
In gaseous state, water vapor can be decomposed to hydrogen and oxygen and this is a reversible reaction.
2H₂(g) + O₂(g) ⇄ 2H₂O (g) Keq
Let's make the expression for the equilibrium constant
Products / Reactants
We elevate the concentrations, to the stoichiometry coefficients.
Keq = [H₂O]² / [O₂] . [H₂]²
Keq = 0.250² / 0.8 . 0.6² = 0.217
Answer:
Reaction between an oxygen and a phosphorus will produce oxides of phosphorus.
Explanation:
Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.

<h2>Answer with explanation:</h2>
<em><u>Beer's Law is described as if a light passes from a solution, the concentration of the solution is directly proportional to the absorbance of light by that solution.</u></em>
Every element has a definite of absorbance of light.
In the testing of food, drugs or in medical testing, the light is passed from the sample.
Them transmitted light from these samples are measured. The difference between target light amount and transmitted light is the amount of absorbed light.
From this absorbed light value, we can identify an element in sample and its quantity.
Spectrophometry is based on this law.
