Unit 2 AOS 1 - Reactions with Acids Quiz (8A)

What happens when a metal reacts with an acid?

• It produces water and carbon dioxide

• It produces a salt and oxygen gas

• It produces a base and hydrogen gas

• It produces a salt and hydrogen gas.

Give an example of a metal reaction with hydrochloric acid.

• Oxygen

• Zinc

• Gold

• Aluminum

What happens when a non-metal reacts with an acid?

• It forms a metal and releases carbon dioxide gas.

• It forms a salt and releases hydrogen gas.

• It forms a base and releases nitrogen gas.

• It forms water and releases oxygen gas.

Give an example of a non-metal reaction with sulfuric acid.

• Oxygen reacts with sulfuric acid

• Non-metals do not react with sulfuric acid.

• Hydrogen reacts with sulfuric acid

• Carbon reacts with sulfuric acid

What is the chemical equation for a neutralization reaction?

• NaCl + H2O → HCl + NaOH

• H2O + CO2 → H2CO3

• HCl + NaOH → NaCl + H2O

• H2SO4 + NaOH → Na2SO4 + H2O

Explain the process of neutralization with an example.

• When sodium hydroxide reacts with potassium hydroxide, it forms sodium chloride and water.

• When nitric acid reacts with calcium hydroxide, it forms sodium chloride and water.

• When hydrochloric acid reacts with sodium hydroxide, it forms sodium chloride and water.

• When hydrochloric acid reacts with sulfuric acid, it forms sodium chloride and water.

What is an acid-base titration?

• A process for creating a neutral solution

• A technique used to determine the concentration of an acid or base by reacting it with a solution of known concentration.

• A technique for determining the color of an acid or base

• A method for measuring the pH of a solution

Describe the steps involved in conducting an acid-base titration.

• Preparing the solution, adding the titrant to the analyte, recording the volume of titrant used, and calculating the concentration of the analyte.

• Shaking the solution, filtering the mixture, and recording the temperature

• Adding the titrant to the analyte, measuring the pH, and calculating the volume of the analyte

• Mixing the solution, heating the mixture, and measuring the color change

What factors can affect the rate of reaction between an acid and a metal?

• Type of acid used

• Size of the beaker

• Surface area of the metal, concentration of the acid, temperature, and reactivity of the metal

• Color of the metal

How does temperature affect the rate of reaction between an acid and a metal?

• The rate of reaction remains constant at different temperatures.

• The rate of reaction decreases with temperature.

• The rate of reaction increases with temperature.

• Temperature has no effect on the rate of reaction.
