Formula Frenzy
The name of the binary compound Al2O3, which combines aluminum and oxygen.
What is aluminum oxide?
The term for the starting substances on the left side of a chemical equation that undergo change.
What are reactants?
The term for a chemical reaction that releases energy into its surroundings.
What is an exothermic reaction?
These original atomic connections must be completely broken at the start of any chemical reaction.
What are the bonds of the reactants?
The abbreviation "Al" on the periodic table represents this lightweight metal element.
What is aluminum?
The correct chemical formula for the binary ionic compound calcium fluoride, combining a Group 2A and Group 7A element.
What is CaF2?
The term for the final substances found on the right side of a chemical equation.
What are products?
The term for a chemical reaction that must absorb energy from its surroundings to proceed.
What is an endothermic reaction?
These new atomic connections are established at the end of a chemical reaction to create something new.
What are the bonds of the products?
This column number on the periodic table contains the highly reactive element fluorine.
What is Group 7A (or Group 17)?
This is what the prefix hexa- indicates about the fluorine atoms in a single molecule of sulfur hexafluoride.
What is that it has six fluorine atoms?
This specific type of reaction always features oxygen gas as one of its starting reactants.
What is a combustion reaction?
The classification for a combustion reaction where energy is written on the product side of the equation.
What is exothermic?
Breaking chemical bonds always requires an input of this fundamental physical property.
What is energy?
This numerical designation on the periodic table tells you exactly how many protons live inside an element's nucleus.
What is the atomic number?
The chemical formula for dinitrogen monoxide, commonly known as laughing gas.
What is N2O?
The specific reaction type demonstrated by the formula: 4Fe + 3O2 → 2Fe2O3.
What is a synthesis reaction?
The thermal classification for photosynthesis, which requires energy on the reactant side: 6CO2 + 6H2O + Energy → C6H12O6 + 6O2.
What is endothermic?
This specific action occurs to surrounding energy when new chemical bonds are successfully formed.
What is energy released?
Elements found in Group 2A of the periodic table, like calcium, will typically form ions with this specific positive charge.
What is a 2+ charge?
The chemical names of the two substances formed on the right side of this reaction: CH4 + 2O2 → CO2 + 2H2O.
What are carbon dioxide and water?
The specific reaction type demonstrated by the formula: 2NaHCO3 → Na2CO3 + H2O + CO2.
What is a decomposition reaction?
This is exactly where the net energy output comes from when it is released during an exothermic chemical reaction.
What is energy stored in the chemical bonds?
This underlying law dictates that the total number of atoms cannot change during the breaking and forming of bonds.
What is the Law of Conservation of Mass?
This is the structural reason why nonmetal elements share electrons to form covalent binary molecules instead of exchanging them.
What is to achieve a full, stable outer electron shell?
