100

This term describes the loss of electrons in a chemical reaction.

What is oxidation?

100

This number, approximately 6.02 x 10^23, represents the number of particles in one mole of a substance.

What is Avogadro's number?

100

This type of bond is formed when electrons are transferred from one atom to another.

What is an ionic bond?

100

This is the term for the digits in a measurement that are known with certainty plus the first digit that is uncertain.

What are significant figures?

100

This is the basic unit of life, the building block of all organisms.

What is a cell?

200

In a redox reaction, this is the substance that gains electrons.

What is a reductant or reducing agent?

200

This unit is used to express the amount of a chemical substance, equivalent to Avogadro's number of particles.

What is a mole?

200

In this type of bonding, atoms share electrons.

What is covalent bonding?

200

The rule states that your answer should have the same number of decimal places as the number with the fewest decimal places.

What is the rule for significant figures in addition and subtraction?

200

This principle is the foundation of Darwin's theory, explaining how organisms change over time through variations that increase their chances of survival and reproduction.

What is natural selection?

300

This is the typical oxidation number of oxygen in most compounds.

What is -2?

300

In stoichiometry, this term refers to the substance that limits the amount of product formed in a chemical reaction.

What is the limiting reactant?

300

This term describes the slight positive and negative charges on atoms caused by the unequal sharing of electrons in covalent bonds.

What is polarity?

300

This rules states that your answer must have the same number of significant figures as the number with the fewest of these in the problem.

What is the rule for sig figs in multiplication and division?

300

This molecule carries the genetic instructions used in the development, functioning, and reproduction of all known living organisms and many viruses.

What is RNA?

400

This rule helps determine the oxidation state of an element in a compound: the sum of the oxidation states must equal this.

What is the charge of the molecule or ion?

400

This stoichiometric calculation is used to convert moles of one substance in a chemical reaction to moles of another substance.

What is a mole-to-mole ratio?

400

This type of covalent bond involves the sharing of two pairs of electrons between two atoms.

What is a double bond?

400

This term describes the closeness of a measured value to its true value.

What is accuracy?

400

This system in the human body is responsible for transporting oxygen, nutrients, and other substances throughout the body, and is composed of the heart, blood, and blood vessels.

What is the circulatory system?

500

This process involves the reduction of carbon dioxide into glucose in plants.

What is photosynthesis?

500

The law that states that matter is neither created nor destroyed in a chemical reaction, which is foundational for stoichiometric calculations.

What is the Law of Conservation of Mass?

500

This rule states that atoms form bonds to achieve an electron configuration of the nearest noble gas, usually eight electrons in their outer shell.

What is the octet rule?

500

This system of units is used globally in science to report measurements, including length, mass, and volume.

What is the International System of Units (SI)?

500

his is the name of the process by which organisms maintain a stable internal environment despite changes in the external environment.

What is homeostasis?
