In a chemistry class, Ava, Abigail, and Kai were given samples of three binary acids: H₂S, H₂Se, and H₂Te. They were asked to identify the weakest one. Which binary acid do you think they found to be the weakest?

• H₂Te

• H₂Se

• All would have the same acid strength

• H₂S

In a chemistry class, Lily, Benjamin, and Avery are discussing the strength of a binary acid. They come up with different statements. Which of the following statements is/are correct about the strength of a binary acid?

• Lily says: 'The strength of a binary acid depends on the electronegativity and size of the nonmetal.'

• Benjamin says: 'Higher the electronegativity of the nonmetal, stronger the binary acid.'

• Avery says: 'The bigger the size of the nonmetal, stronger the binary acid.'

• All the statements made by Lily, Benjamin, and Avery are correct.
