Question

c)
Differentiate between the following:
i)combustion and oxidation

ii)complete and incomplete combustion
iii)spontaneous and rapid combustion
iv)spontaneous combustion and explosion
​

Answer 1

Answer:

Explanation:

1.combustion and oxidation

Combustion is the complete oxidation of organic compound into carbon dioxide and water molecules in presence of oxygen gas whereas oxidation is the addition of oxygen in a compound or addition with an element. ... Combustion reactions involve heat and light whereas oxidation reaction does not involve heat.

2.complete and incomplete combustion

Complete combustion occurs when there is enough oxygen to completely use up all the reactants. Incomplete combustion occurs when there is not enough oxygen resulting in the production of smoke, and less energy is produced when compared with complete combustion.

3.spontaneous and rapid combustion

RAPID COMBUSTION = When a substance bursts in a short span of time, the combustion of the substance is almost complete and a large amount of heat and light is produced. ... SPONTANEOUS COMBUSTION = In this type of combustion, a substance catches fire as soon as its temperature reaches the ignition temperature.

4.spontaneous combustion and explosion

​Spontaneous combustion: The combustion in which substances suddenly burst into flames, without the application of any apparent cause is called spontaneous combustion. ... The combustion in which sudden reactions take place on ignition of some substances to produce heat, light, and sound is called explosion.

Answer 2

Answer:

HI MATE HERE IS UR ANSWER✌✌

Explanation:

★★★★★★★★★

★★★★★★★★★★★★

★★★★★★★★★★★★★★★

1 . OXIDATION IS ADDITION OF OXYGEN IN A COMPOUND TO BREAK IT INTO SIMPLER FORMS WHILE AS COMBUSTION IS COMPLETE OXIDATION OR BURNING WITH THE HELP OF OXYGEN RELEASING WATER VAPOURS AND CARBON DIOXIDE.

2 : COMPLETE COMBUSTION IS WHEN NO RESIDUE IS LEFT BEHIND AFTER THE CHEMICAL PROCESS FINISHES WHILE AS IN INCOMPLETE COMBUSTION RESIDUE LIKE UNBURNT CARBON AND SMOKE ARE LEFT BEHING LPG HAS COMPLETE COMBUSTION AND WOOD HAS INCOMPLETE COMBUSTION.

3 : SPONTANEOUS COMBUSTION IS WHEN A THING BURNS SUDDENLY WITHOUT BREAKS UNTILL ITS BURNT. RAPID COMBUSTION IS WHEN A THING BURNS VERY FASTLY WITH A GREAT SPEED FOR EG : MAGNESIUM RIBBION BURNS WITH A FLASH.

4 : SPONTANEOUS COMBUSTION IS WHEN A THING BURNS SUDDENLY AND EXPLOSION IS A RAPID REACTION OF MANY NUCLEAR COMPOUNDS.
