The concave lens is a lens which has an inward curve in the middle, that is, the edges of the curve are thicker than the center of the lens, because of this, any light that enter the lens will spread out [diverge]. An image will look smaller and upright when viewed by a concave lens. Image formed by concave lens are usually VIRTUAL.
A concave lens will produce a real image ONLY if the object is located beyond the focal point of the lens.
A convex lens is a converging lens, this is because, the center of the lens is thicker than its edges. Any ray of light that passes through the lens will converge at the middle of the lens at point called principal focus. A convex lens produce a VIRTUAL image when the object is placed infront of the focal point. The virtual image formed is always magnified and upright.
The image formed by any lens like concave and convex may be real or virtual.
How many types of lens are present?
Mainly two types of lens are present and that are concave lens also known as divergent lens and convex lens, also known as convergent lens.
- Any light passing through the lens will disperse [diverge]. When viewed through a concave lens, an image seems smaller and more upright. Concave lenses frequently produce VIRTUAL images and concave lens will produce a real image only if the object is located beyond the focal point of the lens.
- Any beam of light passing through the lens will converge in the lens's center, known as the main focus. When an object is placed in front of the focal point, a convex lens produces a VIRTUAL image. The resulting virtual picture is constantly amplified and oriented vertically.
Hence image formed by a lens may be real or virtual.

Explanation:
A balanced equation is defined as the one that has equal number of atoms of all the elements present on both reactant and product side.
(a)
Number of atoms on reactant side are as follows.
Mg = 1
O = 6
H = 3
Cl = 1
Number of atoms on product side are as follows.
Mg = 1
O = 9
H = 2
Cl = 2
So, to balance this equation we multiply by 2 on reactant side and multiply
by 2 on product side.
Therefore, the balanced reaction equation is as follows.
(b)
Number of atoms on reactant side are as follows.
S = 1
O = 4
H = 2
Number of atoms on product side are as follows.
S = 1
O = 4
H = 2
Therefore, this equation is balanced as it has same number of atoms on both reactant and product side.
(c)
Number of atoms on reactant side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Number of atoms on product side are as follows.
Sr = 1
O = 1
H = 2
S = 1
O = 4
Therefore, this equation is balanced.

Explanation:
In this case, we have 2 types of reactions. is a strong base but only has 2 carbons therefore we will have less steric hindrance in this base. So, the base can remove hydrogens that are bonded on carbons 1 or 6, therefore, we will have a more substituted alkene (1-methylcyclohex-1-ene).
For the we have more steric hindrance. So, we can remove only the hydrogens from carbon 7 and we will produce a less substituted alkene (methylenecyclohexane).

Answer : The correct option is, (C) NH₃ + H⁺
Explanation:
Hydrolysis : It is defined as the chemical reaction in which the breakdown of compound takes place due to reaction with water.
As per question:
First ammonium chloride completely dissociates into ion.
Now ammonium ion react with water to give ammonia and hydronium or hydrogen ion.
The balanced hydrolysis reaction will be:
Hence, the correct option is, (C) NH₃ + H⁺
Answer:
NH₃ and H⁺
Explanation:
The dissociation of NH₄Cl will lead to two ions , i.e. , NH⁴⁺ and Cl⁻ .
Hence , the reaction is -
NH₄Cl → NH⁴⁺ + Cl⁻
We can conclude that NH₄Cl can be formed from the ions , NH⁴⁺ and Cl⁻
Hence ,
According to the reaction ,
NH⁴⁺ + H₂O ⇆ NH₃ + H₃O⁺
Therefore ,
The reactant that will lead to the formation of NH₄Cl are - NH₃ and H⁺
