Why Study Chem? It’s everywhere!

Chemicals are everywhere from fluoride to peroxides to baking soda in toothpaste

To detergents and soaps that break oils and grease To fuels found in lighters and mousse Ozone found in the atmosphere To vitamins and minerals (iron) you consume To the lead in gasoline that helps form a combustion

reaction To pressure caused by molecules moving at high speeds To acids that cause heartburn to bases that relieve

heart burn

2 Density Lab Notes: Density by Displacement

Top Jobs in America

Why did the mixtures separate?

Density of a regular shaped object

Density is the mass per unit of volume

Density = Mass

Volume

Very large mass in a very small space, then we say that it is very dense.

Very small mass in a very large space, then we say that it is not very dense.

Manipulating Variables

Example: Find the density of this cube if the mass is 45 grams.

Density = m/ v

D = m / (l x w x h)

D = 45 grams / 90 m3

D = 0.5 g/m3

Draw box with measurements

Is this very dense or not very dense?

Is this very dense or not very dense?

.

Calculating Volume by Displacement

Many objects have odd shapes and don’t have an easy way to calculate its volume.

Volume by displacement is an easy way to calculate volume.

1. Measure initial volume (4.8mL)

2. put object you want to measure inside. Find the final volume (5.6mL)

3. Volume of dinosaur is difference:

5.6-4.8 = 0.8mL

Formulating a Hypothesis

A hypothesis is an educated guess or a proposed explanation to why you think something is happening.

Usually given as an “If _______, then ______” statement.

Example: If I put salt in water, then it will dissolve.

NOTE – A hypothesis must be testable

Write a Hypothesis for this Lab
