The characteristics of two different types of reactions are shown below: Reaction A: Electrons are gained by the atoms of an ele
ment. Reaction B: Protons are lost by the atom of an element. Which statement is true about the atoms of the elements that participate in the two reactions? (5 points) Their identity changes in both Reaction A and Reaction B. Their identity changes in Reaction A but not in Reaction B. Their identity changes in Reaction B but not in Reaction A. Their identity remains the same in both Reaction A and Reaction B.
Their identity changes in Reaction B but not in Reaction A.
Explanation:
Reaction A describes a chemical reaction. Chemical reactions change the structures of substances and cause a gain or loss of electrons. Gaining or losing electrons will not change the identity of an atom.
Reaction B describes a nuclear reaction, which either splits the nucleus apart or combines two smaller nuclear. Nuclear reactions cause a gain or loss of protons and neutrons by the atom of an element, thereby changing its identity.
The breakdown of mass percentage of the elements is determined by dividing molar masses to the total molar mass of the compound (246.37 g/mol). There are four elements: for Mg: 9.87%, S:13.01%, H:5.69%, 71.44%.
