Hydrogen chloride (HCl) is an acid called hydrochloric acid. It is extremely dangerous and proper safety equipment is required. Sodium hydroxide is a dangerous base. When sodium hydroxide reacts with hydrochloric acid, sodium chloride and water are produced. In addition, energy is released as a result of the reaction. At the conclusion of the reaction, there are 95 grams of products.

4. How many grams of reactants must have been used?

D-no effect on the rate

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
