100
This substance speeds up a chemical reaction by reducing its activation energy.
What is catalyst?
100
Chemical reactions that start spontaneously do this with energy.
What is release?
100
Once the enzyme reaction is complete, these break off of the enzyme.
What is product(s)?
100
Type of reaction that creates one product from two reactants.
What is synthesis?
100
4 Na + O2 ⇒ 2 Na20 Is this balanced (ps subscripts don't work on this program, so assume the Na2O is written correctly)?
What is yes?
200
A protein catalyst is this.
What is enzyme?
200
Chemical reactions that do not start spontaneously need this to be added to begin.
What is energy (also called activation energy) which is usually given in the form of heat or light?
200
Enzymes primarily function on these two types of reactions.
What is synthesis and decomposition?
200
Type of reaction with one reactant and two products.
What is decomposition?
200
__ SF6 ⇒ __ S + 3 F2 is this type of reaction.
What is decomposition?
300
The effect of changing pH or temperature on enzymes.
What is reducing its effectiveness by changing the shape of the enzyme/protein.
300
Enzymes only catalyze this many reactions.
What is one?
300
Once the enzyme has completed the reaction, it is no longer useable (T or F).
What is false?
300
Type of reaction where one more reactive element replaces one less reactive element (one-swap)?
What is single replacement?
300
__ C2H4 + ___ O2 ⇒ ___ CO2 + ___ H2O What is the order of coefficients in this balanced reaction?
What is 1, 3, 2, 2?
400
The energy required to start a chemical reaction that does not start spontaneously.
What is activation energy?
400
In order for an enzyme to calatyze a reaction, it must bind with the reactants. Once it does this, the reactants and enzyme form this.
What is enzyme-substrate complex?
400
A reaction that releases heat.
What is exothermic?
400
Type of reaction where two elements exchange places (two-swap dance)?
What is double replacement?
400
__Al + __ Fe2O3 ⇒ ___ Fe + __ Al2O3 The type and coefficients in this balanced equation.
What is single replacement and 2, 1, 2, 1?
500
The forces that hold molecules of substances together are called this (hydrogen bonds are an example)?
What is Van der Waals?
500
In an enzyme catalyzed reaction, the reactants are called this.
What is substrate?
500
A reaction that absorbs heat.
What is endothermic?
500
Type of reaction with a hydrocarbon and oxygen.
What is combustion?
500
__ KCl + __ AgNO3 ⇒ __ AgCl + __ KNO3 The type and coefficients in this balanced equation.
What is double replacement and it is already balanced?
