How many grams of iorn reacts with 71 grams of chlorine to produce 117 grams of sodium chloride

The answer to your question is: 71 g of Chlorine

Explanation:

Na = 46 g

Cl = ?

NaCl = 117 g

Equation

                     2 Na     +     Cl₂   ⇒   2 NaCl          

                     46g              X              117g

If we consider the law of conservation of matter, we know that the mass of the reactants equals the mass of the products, then

                   mass Na + mass Cl₂  = mass NaCl

                    46 g + X = 117

                    X = 117 - 46

                   x = 71 g of Chlorine        

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
