What is a heat reaction?
This the heat released during a chemical reaction.
What changes did you observe in the enzyme reaction and control reaction conical tubes during the time that the reaction was occurring?
You were supposed to observe a change in coloration from the base with added products being made.
Which describes what happens during a chain reaction?
Neutrons released during a fission reaction trigger other fission reactions.
What is released by an exothermic reaction?
what is released during a chemical reaction is ENERGY.
Describe why the indicator reaction is pH dependent?
An indicator reaction is always pH dependent because it involves hydrogen. During the reaction, hydrogen ions are either released or captured during the process.
What is the reaction when zinc reacts with sulphuric acid?
We can see bubbles of gas being released. The gas is a new substance, so this is evidence that a chemical reaction is taking place. the gas released during this reaction is hydrogen.
What is being produced when bubbles are present during a chemical reaction?
a gas
What is released during the light reaction?
Carbon dioxide is released during the light reaction.
Is energy absorbed or released during a decomposition reaction?
Energy is released during a decomposition reaction.
What substance is released during the light reaction?
Carbon dioxide is released during the light reaction.
Give you a sentence for chemical properties?
Bubbles and foam are chemical properties that can happen during a chemical reaction.
What is a heat reaction?
This the heat released during a chemical reaction.
What is light reaction and dark reaction?
Photosynthesis can be divided into two part: light reaction is the first stage of photosynthesis, occurring only in the presence of light, during which energy captured from light drives the production of ATP. dark reaction is the second stage of photosynthesis, not requiring light to occur, and during which energy released from ATP drives the production of organic molecules from carbon dioxide.
What is the effervescence test?
The formation of gas bubbles in a liquid during a reaction is called effervescence. It is the process of bubbling as gas escapes.
What changes did you observe in the enzyme reaction and control reaction conical tubes during the time that the reaction was occurring?
You were supposed to observe a change in coloration from the base with added products being made.
What does bubbling indicate in a chemical reaction?
The creation of bubbles in a liquid can result from:Boiling (formation of gas phase material) a physical changeDissolution of dissolved gasses (a physical change) from a liquid as it warmsThe creation of gases by reactants in an aqueous environment (chemical change)
Is burning wood an example of an exergonic or endergonic reaction?
Yes, combustion is an example of an exergonic reaction. During combustion, energy is released- making it an exergonic reaction.
