JEE State Boards Byju's Answer Reaction of HCl with Metals Metal compound A reacts with dilute Hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is Calcium chloride. Understanding the chemical reaction:

A magnesium ribbon should be cleaned before burning to remove the oxide deposits present on d ribbon. The ribbon should be cleaned thoroughly cleaned with sandpaper.the oxide deposits are formed due to corrosion. Thank Writer Blurt Anonymous answered

that the following formula is consistent with the FERC approach for calculating LHV of fuels by excluding from the higher heating value of such fuels “the latent heat of water vapor formed in the combustion of hydrocarbon fuels.” See 45 FR 17962. Under this formula, the relationship

answer : When magnesium ribbon kept in air. magnesium ribbon gets covered with a white layer of Magnesium oxide. that is why, first of all, we should remove this layer of Magnesium oxide from the magnesium by rubbing with sand paper before burning it in air. सब्सक्राइब करे youtube चैनल

Magnesium ribbon should be cleaned before burning in air because Magnesium metal reacts with oxygen-rich air and creates a very stable compound, i.e. Magnesium Oxide (MgO). It is therefore necessary to clean the ribbon to remove the layer of MgO in order to prevent further reactions with Oxygen. RELATED: How To Take Magnesium Citrate Laxative

Methane releases its chemical energy by undergoing hydrocarbon combustion. Below is a hydrocarbon combustion animation showing the net reaction that occurs when methane combines with oxygen. The hydrocarbon combustion reaction releases heat energy and is an example of an exothermic reaction.

Why should magnesium ribbon be cleaned before it is burnt in air ? A. Magnesium is an extremely reactive metal. When stored, it reacts with oxygen to form a layer of magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper.

Hydrogen fuel refers to hydrogen which is burned as fuel with oxygen. It can be a zero-carbon fuel, provided that it is created in a process that does not involve carbon. Though there are many types of hydrogen like green, blue, grey, black or brown hydrogen owing to the various methods of processes by which they come by.
