Chemical Reactions
The process by which atoms are rearranged to form new substances.
What is a chemical reaction?
The mass of a given chemical element/compound divided by the amount of substance (mol)
What is molar mass?
A substance that dissolves in a solvent to form a soultion.
What is solute?
It Neutralizes acid, and has a pH greater than 7
What are some properties of a base?
Are proton's donors.
What is an acid?
The substance to the right of the arrow in a chemical reaction.
What is a product?
The number that always goes with "moles in the conversion factors.
What is 1 mole?
The substance in which the other substance is dissolved.
What is the solvent?
Acids will make litmus paper turn this color.
What is red?
The substance to the left of the arrow in a chemical reaction.
What is a reactant?
A chemical reaction in which one element is replaced by another compound.
What is a single displacement reaction.
The number found on the periodic table is a weighted average of all isotopes of that element.
What is average atomic mass?
An intensive property of the combination of two substances.
What is solubility.
Has a pH less than 7
What is an acid?
pH = -log ( 1.0 x 10^-2 ) = 2
What is the pH of the solution that has a [H3O+] = 1.0 x 10-2 M?
What is an example of a combustion reaction?
Molar Mass of NaCl
What is 58.44 g/mol ?
A solution in which as much solute as possible has been dissolved.
What is a saturated solution?
[OH-] = 1.0 x 10-5 M
What is a base?
M= 3.5 mol/ 7L = 0.5 M.
What is the molarity of the solution that has 3.5 moles of solute in 7 L of solution?
MgBr2 + _NaF ----> _ MgF2 + _ NaBr
What is an example of a double displacement reaction?
Molar mass of Mg(OH)2
What is 58.3 g/mol
When you add more solvent to the solution the concentration becomes more diluted.
When you add more solvent to a solution, such as adding more water to a glass of lemonade, what happens to the concentration?
- [H3O+] x [OH-] = 1.0 x 10-14 ----> [H3O+] x 1.0 x 10^-12 M = 1.0 x 10-14 ----> [H3O+-] = 1.0 x 10-14 / 1.0 x 10^-12----->= 0.01 M
What is the [H3O+] of the solution when the [OH-] = 1.0 x 10-12 M?
Add coefficients to make sure that there are the same number of atoms on each side of the arrow.
