Write the equation for the reaction described:

1.a

1.b Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients.

A precipitate forms when aqueous solutions of potassium phosphate and zinc chloride are combined.

(Use the lowest possible coefficients. Omit states of matter.)

1.c Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coefficients.

A precipitate forms when aqueous solutions of zinc chloride and lead(II) nitrate are combined.

A solid metal oxide, CuO, and hydrogen are the products of the reaction between Cu metal and steam. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) ++ ++ (Use the lowest possible coefficients. Omit states of matter.) ++
