What is a hydrocarbon? Solution: A hydrocarbon is a compound made up of hydrogen and carbon atoms only. What are the three main types of hydrocarbons found in petroleum? Solution: The three main types of hydrocarbons found in petroleum are alkanes (paraffins), cycloalkanes (naphthenes), and aromatics. Name the simplest hydrocarbon. Solution: The simplest hydrocarbon is … Read more

What is a redox reaction? Solution: A redox reaction is a chemical reaction where oxidation and reduction occur simultaneously. Oxidation involves the loss of electrons, and reduction involves the gain of electrons. In the reaction 2H₂ + O₂ → 2H₂O, which species is reduced? Solution: O₂ is reduced because it gains electrons from H₂. What … Read more

What is an electrolyte solution? Solution: An electrolyte solution is a solution that contains ions (anions and cations) and therefore can conduct electricity. What is a non-electrolyte solution? Solution: A non-electrolyte solution is a solution that doesn’t contain ions and therefore cannot conduct electricity. Are all ionic compounds electrolytes? Solution: Generally, all ionic compounds are … Read more

What is a hydrogen bond? Solution: A hydrogen bond is a special type of dipole-dipole interaction that occurs between an electronegative atom and a hydrogen atom bonded to another electronegative atom (typically N, O, or F). What are the three elements that typically participate in hydrogen bonding? Solution: The three elements that typically participate in … Read more

What type of bond will form between a magnesium atom and an oxygen atom? Solution: An ionic bond will form between a magnesium atom and an oxygen atom because one is a metal (magnesium) and the other is a nonmetal (oxygen). Which type of bond exists in a molecule of CH₄? Solution: A covalent bond … Read more

What is the empirical formula of a compound that has 40.0% Carbon, 6.7% Hydrogen, and 53.3% Oxygen by mass? Solution: Based on mass percentage, assume 100 g of the compound. This will give us 40.0 g of Carbon, 6.7 g of Hydrogen, and 53.3 g of Oxygen. Converting these to moles, we have about 3.33 … Read more

What is the stoichiometric coefficient of Oxygen (O₂) in the combustion of Methane (CH₄)? Solution: The stoichiometric coefficient of Oxygen in the combustion of Methane is 2. (CH₄ + 2O₂ → CO₂ + 2H₂O) What mass of Oxygen (O₂) is needed to completely combust 16 g of Methane (CH₄)? Solution: The molar mass of CH₄ … Read more

What is the Law of Conservation of Mass? Solution: The Law of Conservation of Mass states that matter cannot be created or destroyed in a chemical reaction. Define the Law of Definite Proportions. Solution: The Law of Definite Proportions states that a chemical compound always contains exactly the same proportion of elements by mass. Who … Read more

What is the balanced chemical equation for the reaction of Hydrogen (H₂) with Oxygen (O₂) to produce Water (H₂O)? Solution: The balanced chemical equation is 2H₂ + O₂ → 2H₂O. What is the balanced chemical equation for the combustion of Methane (CH₄)? Solution: The balanced chemical equation is CH₄ + 2O₂ → CO₂ + 2H₂O. … Read more
