This specific example of an acid is so common, it's found in our stomachs.

What is HCl / hydrochloric acid?

100

These basic substances are mostly found at home, but can be deadly if drunk or consumed.

What are cleaning products?

100

This property of agents in reaction must be conserved. This is the same property which is affected by the gravitational force.

What is mass?

100

This is the general name for a substance which is dissolved in solution.

What is a solute?

100

Different atoms of the same element have the same number of this particle. Different ions of the same element will differ in the number of this particle.

What is a proton? What is an electron?

200

These values on the pH scale are representative of an acidic substance.

What are the pH values 1-7, not including 7?

200
A pH value is the measure of the concentration of these ions in a given solution.

What are hydronium ions?

200

This property of agents in reaction must be conserved. This is the same property which is affected by the electromagnetic force.

What is charge?

200

These are the two variables identified in order to structure and plan a scientific investigation.

What are the independent and dependent variables?

200

Chemical bonds of this type can be formed by exchanging ions, when the EN difference is above 2.1.

What are ionic bonds?
300
This is an acid which forms hydronium ions in solution.

What is an Arrhenius acid?

300

This is a base which receives a proton in reaction.

What is a Brönsted-Lowry base?

300

This is the quantity represented by the coefficients balanced in a chemical equation.

What is a mole?

300

These particles are released when salts are dissolved in water.

What are ions?

300

Chemical bonds of this type can be formed by sharing ions, when the EN difference is below 1.6.

What are covalent bonds?
400

Water is an example of this type of substance, which is neither an acid or a base but can act as either in reaction.

What is an amphoteric substance?

400

This is the other word used for something which is deemed "basic".

What is "alkaline"?

400

This is the process in which a reactant gains an electron.

What is reduction?

400

Significant figures represent the level of this property of knowledge to a scientist or researcher.

What is uncertainty?

400

Moving your finger left and down along the periodic table, you'll find this value or property decreases.

What is electronegativity?

500

NH3 can only be described as this type of acid.

What is a Brönsted-Lowry acid?

500

Hydroxides like Mg(OH)2 are usually considered this type of base.

What is a strong base?

500

This is the process in which a reactant loses an electron.

What is oxidation?

500

This is the type or system of logic used in the scientific method, which is different from the system of logic used in mathematics.

What is induction/inductive logic? (Abduction/abductive logic is also acceptable.)

500

This is the reason why noble gases are usually non-reactive.
