USE LETTERS FOR ANSWERS, NO NEED TO EXPLAIN a) Substitute symbols and formulas for words.
b) Predict the products. If no reaction occurs, write “NR” after the --> sign. c) Include abbreviations for the physical state.
d) Write out and balance the equation.

6. Mercury is poured into an aqueous solution of zinc nitrate.

7. Solutions of potassium iodide and lead (II) nitrate are mixed. The resulting lead compound is a precipitate.

thank you! :)

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
