Q: What is to blame for water's boiling point (100c) being higher than the boiling points of similar substances? Read this paragraph and choose the correct option from the provided answers: Hydrogen bonds also explain why water's boiling point (100C) is higher than the boiling points of similar substances without hydrogen bonds. Because of water's relatively high boiling point, most water exists in a liquid state on Earth. Liquid water is needed by all living organisms. Therefore, the availability of liquid water enables life to survive over much of the planet. Choices: - electrode bonds - molecular shape - helium bonds - hydrogen bonds A:
(A).
hydrogen bonds

Q: Potassium is a soft, silvery metal that ignites explosively in what? Read this paragraph and choose the correct option from the provided answers: Potassium is a soft, silvery metal that ignites explosively in water. It easily loses its one valence electron to form positive potassium ions (K + ), which are needed by all living cells. Potassium is so important for plants that it is found in almost all fertilizers, like the one shown here. Potassium is abundant in Earth's crust in minerals such as feldspar. Choices: - air - cold - acid - water A:
(A).
water
