Quiz: Can You Pass Chemical Reaction Trivia Test?
Can You Pass the Chemical Reaction Trivia Test? Chemical reactions are a result of mixing specific elements, and the solution can be different based on what the mixture is made of. Take up the quiz below and get to see just how knowledgeable you are about chemical elements and the reactions you would expect when you mix them. All the best!
- 1.61. What is the molar mass of acetylsalicylic (aspirin) with chemical formula C9H8O4?
- A.
29 g/mol
- B.
108 g/mol
- C.
180 g/mol
- D.
196 g/mol
- 2.In a single replacement reaction, why will one metal replace another metal in an ionic compound?
- A.
The metal will replace another metal if it has a smaller mass and thus is able to hit the ionic compound with a higher velocity and thus more energy.
- B.
The metal will replace another metal if it has a larger mass and thus is able to hit the ionic compound with more energy.
- C.
The metal will replace another metal if it can gain electrons more readily than the other metal.
- D.
The metal will replace another metal if it can lose electrons more readily than the other metal.
- 3.The simplest whole-number ratio of atoms in a compound is called the ________.

- 9.When two ionic compounds are dissolved in water, a double replacement reaction can ________.
- A.
Occur if the products are both aqueous solutions of ionic compounds.
- B.
Occur if two of the ions form an insoluble ionic compound, which precipitates out of solution.
- C.
Occur only if the ions form covalent bonds with each other.
- D.
Never occur if the ions react to form a gas, which will bubble out of the solution.
