The equation ba(s) + hcl(aq) bacl2(aq) + h2(g) is an example of which type of reaction?
a. double-replacement
b. combustion
c. single-replacement
d. decomposition

The best answer would be option C. The reaction between barium metal and hydrochloric acid represents a single replacement type of reaction. This is because only the barium replaces or takes the place the hydronium ion from the hydrochloric acid yielding barium chloride and hydrogen gas.

Hbr dissociates to form h+ and br-ca(oh)2 dissociates to form ca2+ and 2oh-the h+ and oh- react to form waterassuming the reactants are dissolved in water, the net reaction is h+ + oh- —> h2oif you’re asked to show all components of the reaction, the complete reaction is 2hbr + ca(oh)2 —> cabr2 + 2h2o

A, it is falling action my have a good day
