Balancing Acid-Base Reactions Quiz

What is the result of an acid like nitric acid reacting with a base like sodium hydroxide?

• Water and salt

• Hydrogen gas

• Carbon dioxide

• Oxygen

What is a common challenge when balancing reactions with atoms appearing in multiple places?

• Atoms can be confusing

• Atoms change their properties

• Atoms are always balanced

• Atoms disappear

In the shortcut method, how is nitrate treated during balancing?

• As a changing ion

• As a disappearing ion

• As a single atom

• As a new molecule

How should water be viewed in the shortcut method for balancing?

• As a single atom

• As a disappearing molecule

• As a combination of H+ and OH-

• As a new molecule

In the simple example, what is the ratio of acidic protons to hydroxides in the reactants?

• 3:1

• 1:2

• 2:1

• 1:1

What is the first step in balancing the complex example involving phosphoric acid?

• Identify acidic and basic components

• Balance calcium ions

• Balance hydrogen atoms

• Balance water molecules

How many acidic hydrogens are present in the reactants of the complex example?

• 2

• 4

• 6

• 3

What is the final balanced equation for the complex example?

• 2 phosphoric acid + 3 calcium hydroxide = 6 water + 1 calcium phosphate

• 3 phosphoric acid + 2 calcium hydroxide = 6 water + 1 calcium phosphate

• 2 phosphoric acid + 3 calcium hydroxide = 3 water + 2 calcium phosphate

• 3 phosphoric acid + 2 calcium hydroxide = 3 water + 2 calcium phosphate

What is the purpose of treating phosphate as a single unit in the shortcut method?

• To simplify balancing

• To change its properties

• To make it disappear

• To create a new molecule

What should you do after mastering the shortcut method?

• Forget the traditional method

• Only use the shortcut method

• Try balancing using the traditional method

• Ignore the shortcut method
