Be sure to answer all parts. Write the unbalanced chemical equation to represent each of the following reaction statement. Do not include phase abbreviations. (a) Potassium hydroxide and phosphoric acid react to form potassium phosphate and water. (b) Zinc and silver chloride react to form zinc chloride and silver. (c) Sodium hydrogen carbonate reacts to form sodium carbonate, water, and carbon dioxide. (d) Ammonium nitrite reacts to form nitrogen and water. (e) Carbon dioxide and potassium hydroxide react to form potassium carbonate and water.

Explanation:

An unbalanced chemical equation does not show equal number of atoms of each element on both sides of the reaction equation.

a) KOH + H3PO4 > K3PO4 + 3H20

b) Zn + AgCl > ZnCl2 + Ag

c) NaHCO3 → Na2CO3 + H2O + CO2

d) NH4NO2 > N2 + H2O

e) CO2 + KOH > K2CO3 + H2O

chemistry sucks a**

explanation:

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
