How much strong is a pH compared to the next number?
A pH of 10 is 10 times the pH of 9. A pH of 5 is ten times the pH of 4. etc.
Letter representation of synthesis is:
A+B ----> AB
What is an enzyme?
Catalysts containing carbon. They speed up chemical reactions.
What is a constant of an acid?
Hydrogen (H+) ions.
What is an exchange reaction?
When the atoms of one compound trade places with the atoms of another compound
What is used to make co-enzymes?
Some vitamins are used to make co-enzymes.
What is an example of an acid?
HCl--(aq)--> H+ Cl-
What is an example of synthesis?
CO2 + H2O ---> H2CO3
Carbon dioxide and water become carbonic acid, or soda.
Letter representation of exchange is:
What are the steps of an enzyme working?
Step 1: The chemicals key into the enzyme.
Step 2: The chemical reaction happens.
Step 3: The chemicals leave when the chemical reaction has happened.
Is water an acid or a base?
Water is neutral.
Describe the structural formula of a rearrangement reaction.
What is a rearrangement reaction?
When the number and type of atom don't change, but the bonding pattern changes.
What is an aqueous solution?
A solution that is mostly water.
What is the equation for salt becoming salt?
Na+ + Cl- ----> NaCl
What is the equation for a salt?
Acid+ base = water + salt
What is a decomposition reaction?
A single compund breaking down into two or more smaller compounds.
How does an enzyme work?
The chemicals enter the enzyme (like a lock to a key).
What is a catalyst?
A chemical substance that speeds up a reaction without being changer at the end of the reaction.
How many types of reactions can an enzyme speed up?
An enzyme can speed up one type of reaction.
What happens if an enzyme is taken over by a poision?
The cells will destroy the enzyme and create a new one.
What are buffers?
Buffers are chemical compunds (weak acids) that combine with the extra acid, base to remove them and create a pH of 7 (neutral)
What is pH?
The power of hydrogen, a mathematical way to measure the strength of an acid or a base.
What kind of charge does an ionic compound have?
It has a neutral charge/ no charge.
What is a salt?
The result of a chemical reaction between an acid and a base that doesn't dissasociate to produce H+ or OH-.
What are the types of chemical reactions?
Letter representation of rearrangement is:
What is an isotope?
Atoms of an element with a different number of neutrons than the other.
What happens when an ionic compund is put in water?
When an ionic compund is put in water, it has a tendency to break apart (dissasociate).
What is the rule of enzyme specificity?
An enzyme can only fit one type of chemical into itself.
