Chemical Reactions Quiz Part B ACARA

William was observing a science experiment where Lily was burning a piece of paper and Benjamin was mixing vinegar with baking soda. He wondered, which of these experiments involve energy transfer?

• Neither Lily's combustion nor Benjamin's reactions of acids

• Both Lily's combustion and Benjamin's reactions of acids

• Benjamin's reactions of acids only

• Lily's combustion only

Aria, Michael, and Noah are in a chemistry lab. They are given a task to investigate certain reactions. Which of the following reactions should they perform to investigate reactions of acids with metals, bases, and carbonates?

• Reactions of acids with metals, bases, and carbonates

• Combustion reactions

• Photosynthesis reactions

• Respiration reactions

Benjamin, Grace, and Priya are conducting a science experiment. They are trying to understand the role of oxygen in the combustion of a candle. What is the role of oxygen in this scenario?

• It is a reactant in the combustion of the candle

• It is a product of the combustion of the candle

• It acts as a catalyst in the combustion of the candle

• It has no role in the combustion of the candle

James, Nora, and Kai were discussing about different reactions. James mentioned reactions of acids with metals, bases, and carbonates. Nora talked about respiration reactions. Kai brought up photosynthesis reactions. However, they were curious to know which of these reactions affect the environment. Can you help them?

• Reactions of acids with metals, bases, and carbonates

• Respiration reactions

• Photosynthesis reactions

• Combustion reactions

Ava was studying for her chemistry exam and came across a question. She asked Elijah and Hannah for help. The question was: 'Which type of reactions, that we encounter in our daily lives like burning of wood or reactions of acids with metals, bases, and carbonates, are classified as exothermic or endothermic?'

• Only the burning of wood (Combustion reactions)

• Only the reactions of acids with metals, bases, and carbonates

• Neither burning of wood nor reactions of acids

• Both burning of wood and reactions of acids

Grace, Avery, and Jackson were discussing a science project on different types of reactions. Grace asked, 'What is the main difference between combustion, like a burning candle, and other oxidation reactions, like rusting of iron?'

• The involvement of metals

• The involvement of acids

• The absence of oxygen

• The presence of oxygen

Emma, Arjun, and Daniel are studying for their biology exam. They are discussing the types of reactions that play a role in biological processes. Which of the following reactions do you think they would be discussing?

• Respiration and photosynthesis

• Combustion reactions

• Reactions of acids with metals, bases, and carbonates

• Oxidation reactions

David and Ethan are having a bonfire. Olivia is curious about the process and asks, 'What is the product of this combustion reaction?'

• Carbon dioxide and water

• Oxygen and water

• Carbon dioxide and nitrogen

• Oxygen and nitrogen

Anika, Aria, and Sophia are conducting a science experiment in their school lab. They want to understand the role of oxygen in combustion reactions. What type of reactions should they investigate?

• Combustion reactions

• Photosynthesis reactions

• Reactions of acids with metals, bases, and carbonates

• Respiration reactions

Isla, Zoe, and Ava are studying for their science test. They come across a question that asks them to compare two biological processes. Which of the following options should they choose if they want to compare respiration and photosynthesis?

• Combustion reactions

• Reactions of acids with metals, bases, and carbonates

• Respiration and photosynthesis
