• Sodium chloride and silver nitrate

• Silver nitrate and sodium chloride

Evelyn, Aria, and Avery are conducting a chemistry experiment in their school lab. They are performing a double replacement reaction. At what point does the formation of a precipitate occur in their experiment?

• When they mix two aqueous solutions together

• When they cause a reaction between two gases

• When they cause a reaction between a solid and a gas

• When they cause a reaction between a solid and a liquid

During a chemistry experiment, Abigail mixed hydrochloric acid with sodium sulfide. Nora and Hannah observed the reaction. What gas was produced in this double replacement reaction?

• Sodium chloride gas (NaCl)

• Sodium sulfide gas (Na2S)

• Hydrogen sulfide gas (H2S)

• Hydrogen chloride gas (HCl)

Grace and Evelyn were conducting a chemistry experiment in their school lab. They mixed two aqueous solutions of ionic compounds in a double replacement reaction. Arjun, observing their experiment, asked, 'What is the most common product formed in such a reaction?'

• acid

• gas

• precipitate

• solid

Grace, Kai, and Emma are in a chemistry lab. They are given lead(II) nitrate and potassium iodide and asked to perform a double replacement reaction. What would be the product of their experiment?

• Potassium iodide and lead(II) nitrate

• Lead(II) sulfate and potassium chloride

• Sodium nitrate and calcium iodide

• Lead(II) iodide and potassium nitrate

Michael and Emma are conducting a double replacement reaction experiment in their chemistry class. Abigail, their teacher, asks them to observe and tell when the formation of a gas occurs. What should be their answer?

• When both reactants they are using are gases

• When they perform the experiment in a vacuum

• When one of the products of their reaction is a gas

• When the temperature in the lab is extremely low

Liam, Daniel, and James are conducting a chemistry experiment in their school lab. They are trying to observe the product of a double replacement reaction when they mix calcium chloride and sodium carbonate. What would be the product of their experiment?

• sodium carbonate and calcium chloride

• sodium chloride and calcium hydroxide

• sodium chloride and calcium carbonate

• calcium carbonate and sodium chloride
