Group of answer choices LaTeX: A) Ca\:+Cl_2\:\longrightarrow\:CaCl C a + C l 2 ⟶ C a C l LaTeX B) Ca\:+Cl_2\:\longrightarrow\:Ca_2Cl C a + C l 2 ⟶ C a 2 C l LaTeX C) 2H_2\:+O_2\:\longrightarrow\:2H_2O 2 H 2 + O 2 ⟶ 2 H 2 O LaTeX D) H_2\:+O_2\:\longrightarrow\:H_2O

Answer 1

Answer: $2H_2+O_2\longrightarrow 2H_2O$

Explanation:

Law of conservation of matter : It states that matter can neither be created nor be destroyed but it can only be transformed from one form to another form.

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

A) $Ca+Cl_2\longrightarrow CaCl$

B) $Ca+Cl_2\longrightarrow Ca_2Cl$

C) $2H_2+O_2\longrightarrow 2H_2O$ is correctly balanced as the number of atoms of hydrogen and oxygen are equal on the both side of the reaction.

D) $H_2+O_2\longrightarrow H_2O$
