Capitolo 1, Problema 43b
Hydrogen peroxide, often used in solutions to cleanse cuts and scrapes, breaks down to yield water and oxygen: Hydrogen peroxide, H2O2(aq) → Hydrogen, H2(g) + Oxygen, O2(g)
b. Which of the substances are chemical compounds, and which are elements?
Guida verificata passo dopo passo1
Identify the substances in the reaction: H₂O₂ (hydrogen peroxide), H₂ (hydrogen gas), and O₂ (oxygen gas).
Recall the definition of a chemical compound: A chemical compound is a substance composed of two or more different elements chemically bonded together in a fixed ratio.
Analyze H₂O₂ (hydrogen peroxide): It contains hydrogen (H) and oxygen (O) chemically bonded together, so it is a chemical compound.
Recall the definition of an element: An element is a pure substance consisting of only one type of atom, as found on the periodic table.
Analyze H₂ (hydrogen gas) and O₂ (oxygen gas): Both consist of only one type of atom (H and O, respectively), so they are elements.
