A
(b)
Interpretation:
The balanced equation for the reaction that takes place between the barium metal and nitrogen gas is to be stated.
Concept introduction:
A chemical reaction is a process in which rearrangement of atoms or ions takes place between two reacting species. A balanced chemical equation represents an equation in which all the reactants and the products are written with their stoichiometric coefficient and physical states. The number of atoms of an element on both sides of the equation is equal.

- 3.14 A number of compounds are used in cement, and reactions among them occur when water is added. In one, CaO reacts with Al2O3 and water to form Ca3Al2(OH)12. Write a bal- anced chemical equation for this process.arrow_forwardMany over-the-counter antacid tablets are now formulated using calcium carbonate as the active ingredient, which enables such tablets to also be used as dietary calcium supplements. As an antacid for gastric hyperacidity, calcium carbonate reacts by combining with hydrochloric acid found in the stomach, producing a solution of calcium chloride, converting the stomach acid to water, and releasing carbon dioxide gas (which the person suffering from stomach problems may feel as a “burp”). Write the unbalanced chemical equation for this process.arrow_forward3.88 One Step in the enrichment of uranium for use in nuclear power plants involves the reaction of UO2 with hydro- fluoric acid (HF) solution.
