Decide which element probably forms a compound with chlorine that has a chemical formula most and least similar to the chemical
formula of the compound formed by chlorine and barium
1 answer:
The compound formed by chlorine and barium is as the number of valence electrons in barium is 2 and in chlorine is 1. In this compound, barium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.
Since, barium is an element of Group-2 (alkaline earth metal) so the other element that has a chemical formula most and least similar to the chemical formula of the compound formed by chlorine and barium should be from Group-2 (alkaline earth metal) only which has properties somewhat like barium. So, the element is strontium.
Strontium forms a compound with formula in which strontium acts as a cation and chlorine acts as an anion. The formation of the compound is as shown in the image.

Answer :
(1) The balanced chemical reaction will be,
(2) The balanced chemical reaction will be,
Explanation :
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.
If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.
The coefficient tell us about that how many molecules or atoms present in the chemical equation.
(1) The unbalanced chemical reaction is,
This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.
In order to balance the chemical equation, the coefficient '2' put before the and we get the balanced chemical equation.
The balanced chemical reaction will be,
(2) The unbalanced chemical reaction is,
This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.
In order to balance the chemical equation, the coefficient '8' put before the and the coefficient '4' put before the
we get the balanced chemical equation.
The balanced chemical reaction will be,
