HOMEWORK

They might be giants “Meet the Elements https://www.youtube.com/watch?v=d0zION8xjbM

Chemical Formulas Prefix Meaning Uni- Mono- One Bi- Di- Two Poly- Many

Let’s practice C Co CO An upper case letters symbolizes one element. An upper case letter next to a lower case letter symbolizes one element. An upper case letter next to another upper case letter symbolizes two elements.

Element vs. compound Which of the following are elements and which are compound? Na NO2 Element Compound

Naming compounds CO Carbon monoxide CO2 Carbon dioxide Use the name of the element and a prefix to indicate the number of atoms. CO Carbon monoxide CO2 Carbon dioxide

Let’s practice… H2O C6H12O6 Name the following: NaCl HCl Write the chemical formula: water glucose Sodium Chloride Hydrochloric Acid H2O C6H12O6

Equations Equations are used to describe chemical reactions The substances that start the reaction are called reactants The substances formed by the reaction are called products The arrow means “to make” or “to form”

This is the chemical equation for: Cellular Respiration Reactants products C6H12O6 + O2  CO2 + H2O + Energy
