Which reaction below represents a balanced, single replacement chemical reaction?
a) c2h5oh + 3o2 → 2co2 + 3h2o
b) baf2 + li → lif + ba
c) cd + h2so4 → h2 + cdso4
d) h2o → h2 + o2

Option (C) is the correct answer.

Explanation:

A single replacement reaction is defined as the reaction where an element upon reaction with a compound tends to displace another element in that compound.

For example, is a single replacement reaction.

And, when number of atoms on reactant side equal to the number of atoms on product side then it is known as a balanced chemical reaction.

Thus, we can conclude that represents a balanced, single replacement chemical reaction.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
