What is Rate of Reaction
How fast or slow a reaction is.
Magnesium Block has a ________ surface area compared to Magnesium Powder ( If both have the same mass ) .
Lesser / Lower Surface Area
How can decrease in temperature affect the rate of reaction?
The rate of reaction will become slow.
How to make a acid dilute?
Adding water to the acid.
What does the slope
tell you about the graph.
How quickly the reaction is taking place.
What product is formed when you burn magnesium ribbon with bunsen burner .
Magnesium Oxide
What is a anomalous result?
An anomalous result is a measurement that does not fit the pattern of the rest of the results.
Which will react faster 1) Reaction in dilute acid
2) reaction in concentrated acid
2) in concentrated acid.
What do you use to collect gas
Syringe
What does surface area mean?
Surface area is the total area of a solid reactant exposed to other substances
Will a reaction be faster at 56°C or 52°F?
56°C
What does it mean when results stay constant?
The reaction has ended.
What is the formula to calculate Rate of Reaction
Amount of Gas produced / Time Taken
Each time you cut solid into smaller pieces what happens to the surface area ?
The surface area increases.
A reaction takes 52 seconds on 40°C. The same at different temperature takes 44 seconds. What is the possible temperature?
More than 40°C
What is concentration?
A measure of how many particles of a Substance are in a fixed volume of a solution.
What is the chemical symbol and salt endings for
Nitric Acid
Sulfuric Acid
Nitric Acid - HNO3 , Salts end with Nitrate
Sulfuric Acid - H2S04 , Salts end with sulfate
Why does larger surface area has faster Rate of Reaction
The larger the surface area, More particles are exposed to other substances creating more vigorous and frequent collisions.
What is precipitate
An insoluble solid formed when two soluble substances react.
How is concentration of acid affects the rate of reaction?
Higher the concentration faster the reaction.
