The answer is a
the equation needs to be balanced. There are fewer oxygen atoms in the equation than hydrogen or a carbon
Answer:
The correct answer is "The reactions stop once equilibrum is achieved"
Explanation:
A system is said to have attained equilibrium when the rate of forward reaction is the same/equal to the rate of backward reaction. The reaction below shows a chemical reaction that is at equilibrium
2N₂O₅ (aq) ⇄ 4NO₂ (aq) + O₂ (aq)
An equilibrium reaction is always a reversible reaction. <u>When the system is at equilibrium (when there is a balance), the concentration of the reactants and products do not change despite the fact that reaction does not stop</u>; what happens however is that the rate at which the reactant(s) are formed (backward reaction) will be equal to the rate at which the product(s) are formed (forward reaction).
From the explanation above, it can be deduced that "The reactions stop once equilibrum is achieved" is a misconception about a system in chemical equilibrium.
Answer:
As the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
Explanation:
As the object is moving towards the lens then in that case first the image will form between the focus and double the distance of focus.
So here the image is diminished
now when the object is at large distance from from lens then its image will form at focus and it is of very small size
Now as the object comes closer to the lens till the object distance is 2F the image size will increase but smaller then object size
Now when object is between F and 2F then the image size will be more than object size and it will increase to infinite magnification
So overall we can say that as the object moves parallel to principle axis the image of the object will continuously moves away from the principal axis so the horizontal distance will increase
A controlled experiment is best described as a safe, in depth, and insightful display that helps you understand the purpose of the experiment better
The unpolarized light becomes less intense. When unpolarized light is run through a polarizer, its intensity is diminished by a factor of ½.
<h3>Unpolarized light:</h3>
Unpolarized light is diminished by a factor of ½ when it travels through a polarizer. Cos 2θ averages out across all angles to be ½ in size. I transmitted = I₀ and ½ I₀ at all angles The unpolarized light's intensity decreases to zero.
The light-producing atoms on the heated filament's surface behave independently of one another. Each of these emissions can be roughly represented as a brief "wave train" lasting between approximately 109 and 108 seconds. These wave trains, each with its unique polarization direction, are superimposed to form the electromagnetic wave that is coming from the filament.
Unpolarized light is produced by all common light sources, including the Sun, incandescent and fluorescent lighting, and flames.
