Reaction Rates
A catalyst ______ the rate of a chemical reaction.
What is speeds?
What is increases?
These are sour, sticky, and turn blue litmus red.
What are acids?
Hadissah is warming up next to a campfire and observes that the fire is a particular type of chemical reaction, because it is giving off heat.
What is exothermic?
This spectrum includes many transverse waves, such as radio waves, visible light, and Gamma rays.
What is the electromagnetic spectrum?
This type of energy production is nonrenewable, clean energy, and produces radioactive waste.
What is nuclear energy?
Brooklyn has added a zinc shaving to some hydrochloric acid. Each has a different concentration, and she is looking for the test tube with the fastest reaction.
What is the highest concentration?
Manuela has a solution that reacts with metal and is 4.5 on the pH scale.
What is an acid?
Al2O3 → 2Al + O2
What is a decomposition reaction?
Viviann needs the measure of energy of a wave.
What is amplitude?
Erin knows that the element used in nuclear energy has 92 protons.
What is uranium?
Logan and Raphael are tired of waiting for the chemical reaction of baking powder in water to occur. They see both an ice bath and a hot plate nearby and choose to increase the rate of reaction using one.
What is the hot plate?
Jackson has a solution that turned red litmus blue and is a 10 on the pH scale.
What is a base?
2H2 + O2 → H2O
What is a synthesis reaction?
Jayden's favorite wave on the electromagnetic spectrum has long wavelengths, low frequency, and includes uses such as Wifi, phones, and microwaves.
What is a radio wave?
Christian notices that most nuclear reactors are close to a particular geographic feature, that is used to cool the reactors.
What is water?
Destin has two Alkaseltzer tablets. One got crushed in his backpack, but the other one stayed whole. He decides to test and see which tablet reacts more slowly.
What is the whole tablet?
Ruth has several solutions, including soap, ammonia, and bleach.
What are bases?
Alli twists her ankle during warm ups and the trainer gets her an instant cold pack. She notices that this is a particular type of reaction because it gets cold.
What is an endothermic reaction?
What is the crest?
Ava knows that uranium releases a lot of energy when it breaks down into smaller atoms.
What is fission?
Will is using hydrogen peroxide to make a volcano. He decides to add something to lower activation energy and increase the rate of reaction.
What is a catalyst?
Jonah has a solution that is 7 on the pH scale.
What is neutral?
Cl2 + NaBr → 2NaCl + Br2
What is a single replacement reaction?
Leon knows the measurement from one crest to the next crest, or from one trough to the next trough.
What is wavelength?
Abby has researched nuclear energy to find it produces very little waste, produces a huge amount of energy, and does not produce greenhouse gases.
What are advantages/pros?
