What does it mean for an element to be diatomic?

Back

An element that naturally exists as two atoms bonded together, such as O2 or H2.

Front

What is the general form of a double replacement reaction?

Back

AB + CD → AD + CB, where A and C are cations and B and D are anions.

Front

What are the products of the combustion of hydrocarbons?

Back

Carbon dioxide (CO2) and water (H2O).

Front

What is a synthesis reaction?

Back

A reaction where two or more reactants combine to form a single product.

Front

How do you predict the products of a double replacement reaction?

Back

Swap the anions of the reactants to form new compounds.

Front

What is the significance of subscripts in chemical formulas?

Back

Subscripts indicate the number of atoms of each element in a compound.

Front

What is the balanced equation for the combustion of ethylene (C2H4)?

Back

C2H4 + 3O2 → 2CO2 + 2H2O.

Front

What is the product of the reaction between aluminum and sulfur?

Back
