Answer: The coefficient in front of AlCl_3 is '2'.

Explanation:

Coefficient is defined as number coming before the formula unit of molecule of a compound in chemical reaction.

2Al(s)+3ZnCl2(aq)\rightarrow 3Zn(s)+2AlCl3(aq)

From the balance chemical equation, 2 moles of aluminum are reacting with 3 moles of zinc chloride to give 3 moles of zinc metal and 2 moles of aluminium chloride as a product.

Here, the coefficient of the aluminum chloride is '2'.

Thinner in the center that at the edges; virtual image smaller.
ipn [44]
<h3><u>Answer</u>;</h3>

Concave Lenses

<h3><u>Explanation</u>;</h3>
  • A concave lens is thin in the middle and thick at the edges, such that it seems to cave inwards. It spreads light rays apart producing an image smaller than the actual object.
  • <em><u>Images formed by a concave lens are virtual, upright, reduced in size and located on the same side of the lens as the object. Diverging lenses or concave lens always produce images that share these characteristics. The location of the object does not affect the characteristics of the image. </u></em>

How do CFC’s illustrate that technical advances can be a “double-edged” sword?
hram777 [196]

Answer:

CFC’s illustrate that technical advances can be a “double-edged” sword as CFC's were made for the advantages but soon or later it came as a disadvantage for environment.

CFC's was discovered with many advantages such as they are stable, non-corrosive, and replacement of harmful ammonia used in refrigerators  and air conditioning systems. But soon it is also discovered that CFC's are destroying  the upper atmosphere layer called ozone, which is a very big disadvantage for us. CFCs are major contributor  to global warming after carbon dioxide.

Hence, it proves that CFC’s shows how technological advancement can be “double-edged” sword.
