True or False: You are allowed to have food and drinks in the lab.
What is false?
This type of bond forms when electrons are transferred from one atom to another.
What is an ionic bond?
This type of reaction occurs when two or more substances combine to form one product.
What is a synthesis reaction?
This is the ratio of coefficients in a balanced chemical equation.
What is the mole ratio?
This scale measures how acidic or basic a solution is.
What is the pH scale?
These be worn at all times during a lab?
What are goggles, gloves, and an apron?
This type of bond involves atoms sharing electrons.
What is a covalent bond?
This type of reaction breaks one compound into two or more simpler substances.
What is a decomposition reaction?
This quantity is equal to 6.022 × 10²³ particles.
What is a mole?
Substances with a pH less than 7.
What are acids?
You are required to do this after you finish a lab.
What is washing your hands?
This determines how strongly an atom attracts electrons in a bond.
What is electronegativity?
In this reaction, a more reactive metal replaces a less reactive metal in a compound.
What is a single replacement reaction?
This law states that matter cannot be created or destroyed in a reaction.
What is the law of conservation of mass?
Substances with a pH greater than 7.
What are bases?
This tool is used to safely pick up hot glassware.
What are tongs?
This type of bond occurs when electrons are shared unevenly between atoms.
What is a polar covalent bond?
In this reaction, ions switch partners between two compounds.
What is a double replacement reaction?
This value represents the mass of one mole of a substance.
What is molar mass?
This term describes how concentrated a solution is in terms of moles per liter.
What is molarity?
If an accident happens during the lab, you should do this.
What is alert the instructor?
This bond is formed when one atom donates both electrons to a shared pair.
What is a coordinate covalent bond?
Identify the reaction type:
CH₄ + 2O₂ → CO₂ + 2H₂O
What is a combustion reaction?
This percentage compares actual yield to theoretical yield.
What is percent yield?
This ion is produced by bases in solution.
