Unit 0/1
These numbers include nonzeros, numbers that fall between nonzeros, and any number after a nonzero when a decimal is present.
What are significant figures?
Electrons are found in these specific regions around the nucleus, each with distinct energy level.
What are orbitals?
This type of bond forms when electrons are transferred from one atom to another, typically between a metal and a nonmetal.
What is an ionic bond?
This type of reactions results in separated compounds.
What is decomposition reaction?
What is an acid?
What is the independent variable?
This term descibes the horizontal rows on the periodic table, which indicates the number of energy levels in an atom.
What are periods?
When atoms in a covalent bond have significantly differnet electronegativities, this type of bond is formed.
What is a polar covalent bond?
This law is used in balancing equations to ensure that the reactants and products are equal.
What is the law of conservation of mass?
Used to determine the number of moles of solute per liters of solvent.
What is molarity?
This part of the atom contains protons and neutrons and accounts for most of the atom's mass.
What is the nucleus?
This trend increases across a period and decreases down a group on the periodic table, and it measures an atom's ability to attract electrons in a bond.
What is electronegativity?
This is the chemical formula for Iron (III) Oxide.
What is Fe2O3?
In stoichiometry, this reactant is completely used first, limiting the amount of product formed.
What is the limiting reactant?
The point at which all there phases of matter exist at one time.
What is the triple point?
To calculate the weighted average of an element, you multiply the mass of each isotopes by this value, expressed as a decimal.
What is percent abundance?
The element with the electron configuration [NE] 3s23p5 has this many valence electrons.
What is seven?
This molecular shape has four domains, including two bonds and two sets of lone pairs.
What is bent (tetrahedral variation)?
The molar mass of LiOH.
What is 23.95 g/mol?
The molarity of a diluted solution if 45mL of water are added to 250mL of a 0.75 M solution.
What is 4.2 M or 0.64 M?
This rare-earth element has has an electron configuration the ends in ....4f14 6s2
What is Barium?
When an electron absorbs energy and moves to a higher energy level, it is said to be in this state.
What is the excited state?
This type of intermolecular force arises due to temporary fluctuations in electron distribution, leading to instantaneous dipoles.
What are London dispersion force?
The ratio of Magnesium to Magnesium Chloride in the following equation:
___ Mg + ___ Cl2 --> ___ MgCl2
What is 1:1 (1 to 1)?
The energy needed to start a reaction.
What is the activation energy?
