Types of reactions
What kind of reaction is the following?
A + B -> AB
Combination reaction
Atoms get bigger
What is electronegativity?
A measure of how much an atom wants electrons
What is the octet rule?
A general rule that states that atoms are content with 8 electrons in their valence shell
What type of reaction is the following?
AB+CD -> AD + BC
Double displacement
Which atom is more electronegative K (potassium) or O (Oxygen)?
O (Oxygen)
What is a solute?
The substance to be dissolved
What is the conservation of matter?
Matter cannot be created or destroyed it just changes form
What type of reaction is the following?
AB + C -> AC + B
Single displacement reaction
Which atom is larger F (fluorine) or Cl (Chlorine)
Cl (Chlorine)
What is a cation?
A positively charged ion
A polar substance can be dissolved in a nonpolar solvent?
True or false
False, this is the general rule of like dissolves like
NaOH + HCl -> NaCl + H2O
Double displacement
How many valence electrons does N (Nitrogen) have?
5 valence electrons
What is a precipitate?
A solid that is formed from two solutions being mixed together.
What are the three ways in which a chemist can increase energy in a reaction?
heat, electricity, and high energy light
CO2 + H2O -> C6H12O6 + O2
There are two
Decomposition and breakdown
What charge will a B (Boron) ion develop?
+3
What is an anion?
A negatively charged ion
What is the law of conservation of energy?
Energy cannot be created or destroyed it just transfers from one to another
