Q: Why will water balloons launched into the air eventually burst? Read this paragraph and choose the correct option from the provided answers: Each day, hundreds of weather balloons are launched. Made of a synthetic rubber and carrying a box of instruments, the helium-filled balloon rises up into the sky. As it gains altitude, the atmospheric pressure becomes less and the balloon expands. At some point the balloon bursts due to the expansion, the instruments drop (aided by a parachute) to be retrieved and studied for information about the weather. Choices: - heat - momentum - friction - expansion A:
expansion

Q: What is a reaction in which an atom or molecule is added to an unsaturated molecule, making a single product? Read this paragraph and choose the correct option from the provided answers: An addition reaction is a reaction in which an atom or molecule is added to an unsaturated molecule, making a single product . An addition reaction can be thought of as adding a molecule across the double or triple bond of an alkene or alkyne. Addition reactions are useful ways to introduce a new functional group into an organic molecule. Choices: - complete reaction - homeostasis - single reaction - an addition reaction A:
an addition reaction
