Question

give one example each of the reaction involving combination of (a) an element with another element (b)an element with compound (c)a compound with another compound

Answer 1

Answer:

Hey friend.!!..

.the reactions are here.... :)

Explanation:

 

i)C+O2---->CO2

ii)Mg + 2HCl---->MgCl2+H2

iii) NaOH + HCl-----> NaCl+H2O

Answer 2

Answer:

It is described as a chemical process in which, under the right circumstances, two or more substances combine to form a single substance. When new bonds are formed during combination reactions, a significant amount of energy is released as heat.

Explanation:

(a) an element with another element:

A new compound is created when two elements combine in the first kind of combination reaction.

Example: When nitrogen and hydrogen pass over finely divided iron, they combine to form the gas ammonia, which has a strong odor.

N₂ + 3H₂ → 2NH$_{3}$

(b)an element with compound:

A compound and an element combine in a second type of combination reaction.

Example: When the chemical compound SO₂ and the element oxygen react to form Sulphur trioxide.

2SO$_{2}$ + 0₂ →2S0$_{3}$

(c)a compound with another compound:

The kind of combination involves the fusion of two or more compounds to create a brand-new compound. An illustration of this reaction is the vigorous reaction of lime with water to produce slaked lime, a white powder made of calcium hydroxide.

CaO + H₂O → Ca(OH)₂

• One type of chemical reaction is a combination reaction. It could be described as a chemical reaction where, under the right circumstances, two or more substances combine to form a single substance.
• Similar to how non-metals and highly reactive metals can combine to form covalent compounds. When new bonds are formed during combination reactions, a significant amount of energy is released as heat.
