100
Where is the reactant located?
What is on the left-hand side of the yield sign.
100
What are the 5 factors that affect rate of reaction?
What is temperature, surface area, concentration, catalyst, inhibitor
100
Which type of reaction breaks something down?
What is decomposition.
100
What is the Law of Conservation of Mass?
What is matter cannot be created nor destroyed.
100
What type of reaction involves heat being absorbed?
What is endothermic.
200
What is rate of reaction?
What is the speed it takes for a reaction to take place.
200
Describe two ways to slow down rate of reaction.
What is decrease surface area, decrease temperature, decrease concentration, or use of an inhibitor.
200
What type of reaction has multiple reactants and one product?
What is synthesis.
200
Give a real-life example of the Law of Conservation of Mass.
What is answers will vary.
200
What type of reaction has heat on the reactant side of the chemical equation?
What is an endothermic reaction.
300
The minimum of amount of energy needed to start a chemical reaction.
What is activation energy.
300
Can a catalyst be re-used in a reaction?
What is yes because a catalyst is not part of the reaction and is not used up.
300
What type of reaction is represented by: AB + C--> AC + B?
What is single displacement.
300
If the reactant of an equation has a mass of 110 g, what is the mass of the products?
What is 110 g.
300
Does water freezing on a corn stalk represent an endothermic or exothermic reaction? Explain.
What is exothermic because heat is being released through the freezing process.
400
What is concentration?
What is the amount of substance you have of an object.
400
Why is your car batter more likely to break down in winter?
What is the temperature is lower, which decreases the particle speed. Since there are less collisions, your car is less likely to produce enough energy to start.
400
What type of reaction is represented by the following equation: NaOH + KNO3 --> NaNO3 + KOH? How do you know?
What is it is double displacement because there are two switches, which results in two new compounds forming.
400
If Emanuel has 10 g of carbon and 20 g of oxygen that he combines together, how much carbon dioxide is produced?
What is 30 g
400
Is a car engine an example of an endothermic or exothermic reaction? Explain.
What is exothermic because heat is being released.
500
What is an inhibitor.
What is a substance that slows down a reaction.
500
George wants to have the fastest reaction between vinegar and baking soda. He uses 100mL of vinegar for all three trials, but he changes the amount of baking soda. During trial 1, George used 10 mL of baking soda, 20 mL for trial 2, and 30 mL for trial 3. Which trial will produce the fastest reaction? Why?
What is trial 3 because it has the highest concentration, which means that there is more substance to react with.
500
Compare and contrast single displacement and double displacement.
What is they both are types of chemical reactions and involve elements trading places, but single displacement has one switch and double displacement has two switches.
500
How do chemical equations follow the Law of Conservation of Mass?
What is because they have the same number of atoms on each side of the equation, so matter cannot be created nor destroyed.
500
Give an example of an endothermic reaction and an exothermic reaction. Label each.
What is answers will vary.
