chemical reactions
When does a Synthesis reaction occur?
A Synthesis reaction occurs when two simple substances combine and form a single compound.
What is a mole?
A mole is the counting unit, the number of atoms, ions, molecules, or formula units . One mole of a compound contains Avogadro's number (6.022 x 1023)
What two components make up a solution?
Solute and Solvent are the two componets that make up a solution.
Does the property Acid taste sour or bitter?
The property Acid taste sour.
What is a Decomposition reaction?
Decomposition reactions are opposite of synthesis reactions. They occur when a compound breaks up into simpler compounds.
What is Mass?
The molar mass of a compound tells you the mass of one mole of that substance,number of grams per mole of a compound. units for molar mass,grams/mole.
What is solute?
Solute is a substance that is dissolved.
Does the property Base neutralize bases to form water and salts or neutralize acids to form water and salts?
The property Base neutralizes acids to form water and salts.
When do Single Replacement Reactions occur?
Single Replacement Reactions occur when one element replaces another in a compound.
How many moles are in 15 grams of lithium? (molar mass of lithium is 6.94 g/mol.
15 grams x 1 mole = 2.1614 moles lithium= 2.2moles Li
6.94grams
What is solvent?
Solvent is a substance that does the dissolving.
Does the property Acid have more (>) or less (<) pH?
The propety Acid has less (<) pH.
When do Double Replacement Reactions occur?
Double Replacement Reactions occur when a metal replaces a metal in a compound and a nonmetal replaces a nonmetal in a compound forming two new compounds.
How many grams are in 2.4 moles of sulfur? (molar mass of sulfur is 32.07 g/ mole).
2.4 moles x 32.07 grams = 76.97 grams sulfur =77 g Sulfur
1 mole
What is Concentrated and Dilute?
Dilute is a solution with a relatively small amount of solute and Concentrated is a solution with a relatively high amount of solute.
Is HBr Acid an or Base?
Acid, because it has the (H) hydrogen in the front.
When do Combustion Reactions occur?
Combustion reactions occur when a hydrocarbon reacts with oxygen gas to produce carbon dioxide and water .
How many grams are in 4.5 moles of sodium fluoride, NaF?(molar mass of NaF is 22.99 + 19.00 = 41.99 g/ mole).
4.5 moles x 41.99 grams = 188.955 g NaF =190 g NaF
1 mole
What is Solubility?
Solubility is the maximum amount of solute for a saturated solution in 100 g of water at a specific temperature.
Is Al(OH)3 an Acid or Base?
Base, because the (OH) is at the end.
