CaO(s)+H2тАЛO(l)тЖТCa(OH)2тАЛ(aq)+Heat, this reaction is called:
decomposition reaction
combination reaction
Wurtz fittig reaction
Wurtz reaction
combination reaction
The reaction between calcium oxide (quicklime) and water to form calcium hydroxide (slaked lime) is a combination reaction. In this process, two or more reactants combine to form a single product.
The reaction between calcium oxide (quicklime) and water to form calcium hydroxide (slaked lime) is a combination reaction. In this process, two or more reactants combine to form a single product.
Think of it like two friends joining together to form one group; just like when you mix quicklime with water, they 'combine' to form one new substance, slaked lime.
COMB-ination: Many becoming ONE.
CaO(s)+H2тАЛO(l)тЖТCa(OH)2тАЛ(aq)+Heat тАФ The chemical equation for the formation of slaked lime.
In a combination reaction, multiple substances react to produce one substance. This specific reaction is highly exothermic, meaning it releases a significant amount of heat into the surroundings, and it represents the hydration of an oxide to form a base.
Combination reactions are also known as synthesis reactions.
This reaction is a classic example of an exothermic reaction.
Calcium hydroxide is commonly referred to as slaked lime.
The process is frequently used in traditional whitewashing of walls.
Used for manufacturing slaked lime for industrial and construction purposes.
Releases significant heat, which can be hazardous if handled improperly without adequate water.
Whitewashing of walls.
Neutralization of acidic soil in agriculture.
Decomposition reaction involves breaking one substance into two or more.
Wurtz and Wurtz-Fittig reactions are specific organic synthesis reactions involving alkyl halides and sodium.
Option A is incorrect because it is the opposite of this process. Options C and D are incorrect because they refer to specific organic chemistry reactions involving carbon-carbon bond formation.
B is correct тАФ The reaction represents the combination of two reactants to form a single product, defining it as a combination reaction.
Always identify the number of reactants versus products; if two reactants become one product, it is almost always a combination reaction.
