Identify the single displacement reaction. C4H12 + 7O2 ⟶ 6H2O + 4CO2 2H2 + O2 ⟶ 2H2O Al2S3 ⟶ 2Al + 3S Cl2 + 2KBr ⟶ 2KCl + Br2
Varvara68 [4.7K]

Answer:- Cl_2+2KBr\rightarrow 2KCl+Br_2

Explanations:-  The first reaction is combustion reaction as the hydrocarbon is burned in presence of oxygen to give carbon dioxide and water.

Second reaction is the synthesis reaction as in general a synthesis reaction looks like:

A+B\rightarrow AB

Third reaction is the decomposition reaction as it looks opposite of synthesis reaction.

AB\rightarrow A+B

In general, a single displacement reaction looks like:

AB+C\rightarrow AC+B

Fourth reaction is single replacement reaction as bromine is replaced by chlorine.

So, the correct choice is the last reaction, Cl_2+2KBr\rightarrow 2KCl+Br_2 .

Any deviation in the image of an object when light passing from one medium to other is assciated to the phenomenon of refraction.

<h3>What is refraction ?</h3>

It is the deflection from a straight path undergone by a light ray while passing from one medium (such as air) into another (such as glass) in which its velocity is different.


Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.

<h3 />
  • After Looking at the pencil from the side of a clear glass or resealable plastic bag filled three-fourths with water, we will see the light bends around the pencil, causing it to look bent in the water.

  • When the pencil tilt from side to side, It looks so dramatically broken on looking at it from different angles.
    We can magically “fix” the broken pencil by changing where the pencil is positioned in the glass.

A cylinder with 10 mL of coconut oil has a mass of 9.3 g. What is the density of the oil? Round to the nearest hundredth. ​
lakkis [162]

Answer:

0.93 grams per milliliter

Explanation:

Density is the division of mass by volume. It is how "hefty" an object is; for example, wood isn't very "hefty" but metal is. The density is measured in mass over volume, so it is 9.3/10. After applying units, it is 0.93 grams per milliliter.
