Acid rain is the direct result of acid released by burning fossil fuels. true or false

2 answers:

5 0

<span>True. Acid rain is formed when compounds released during the burning of fossil fuels, such as sulfur dioxide and nitrous oxide, dissolve in water droplets in clouds. These then fall as rain as part of the water cycle. While some rain is naturally acidic, human activities, like burning fossil fuels, have made it worse.</span>

Answer : Option B) False.

Explanation : Acid rain is caused by a chemical reaction between the rain water droplets and the the air pollutants sulfur dioxide and nitrous dioxide. These harmful air pollutants are emitted by the incomplete combustion of the fossil fuels. When it gets combined with the water in the rain it comes down in the form of sulfuric acid and nitric acid, which is very harmful.

Therefore, there is an indirect relation between the burning of the fossil fuels and the acid rain. So, the answer is FALSE.

What is state symbols

Ganezh [65]

Answer:

Explanation:

State symbols are used in chemical equations to delineate the state of matter in which the reaction is taking place.

They give a good perspective of the state of the reactants and products obtainable.

There are basically four states of matter in every chemical reaction:

Solids are symbolized by small letter (s)
Liquids are represented by (l)
Gases are shown by (g)
Aqueous solutions having water as the medium by (aq)

These symbols appear as subscript in front of the chemical species.

Ann [662]

Equilibrium chemical reaction between chair and boat forms is:
Kc = $\frac{[Boat form]}{[Chair form]}$
Suppose the total number of molecules is x
Number of molecules of chair form is 6.42/100 x
Number of molecules of boat form is 93.58/100 x
Kc = $\frac{(0.9358x)}{(0.0642x)}$ = 14.6

Vlad [161]

can be oxidized to form carbon dioxide

Explanation:

Oxygen is important in the oxidation of glucose because it can be oxidized to form carbon dioxide. Oxidation of glucose involves the reaction of oxygen with glucose in a process called respiration. This gives a product of water, carbon dioxide and energy which is stored as ATP.

Oxidation involves the addition of oxygen.
Any specie that undergoes oxidation, is a reducing agent and it is said to be oxidized.
Oxygen is oxidized to form carbon dioxide and water.

An airplane travels with a constant velocity of 210 m/s and in the upper atmosphere where the plane is traveling there is a wind

kolezko [41]

Answer:

hello your question is incomplete the options are missing

Determine the resultant velocity for the plane when it is travelling

i) To the east

ii) To the west

answer :i) 270 i

ii) -150 i

Explanation:

velocity of Airplane = 210 m/s

wind velocity = 60 m/s to the east

The resultant velocity for the plane when it is travelling

let the velocity of the wind = V2

velocity of the plane = v1

i) The resultant velocity for the plane when travelling to the east

Vr = V2 i + V1 i

Vr= 60i + 210i = 270i

ii) resultant velocity when the plane is travelling to the west

Vr = - V1 i + V2i

= -210i + 60 i = -150 i
