Write a balanced equation for the double-replacement neutralization reaction described, using the smallest possible integer coefficients. A reaction occurs when aqueous solutions of sodium hydroxide and hydrochloric acid are combined. (Use the lowest possible coefficients. Omit states of matter.) t item aftempt remaining Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients A precipitate forms when aqueous solutions of ammonium carbonate and silver(1) nitrate are combined.
