How to Find Density

Density = Mass / Volume
Mass = Density x Volume
Volume = Mass / Density

Multiple Choice

A rock has a mass of 14g and a volume of 2cm³. What is the density of the rock?

7 mL

7 g/cm³

28 g/cm³

1/7 g/cm³

Density Column

Depending on the density of object or liquid, it will sink or float in the density column.

When something has a high density (more dense) compare to others then it will sink towards the bottom.

Open Ended

Refer to the density tower that you saw in the video on Slide #4.

Density of water is 1.00 g/mL and dish soap is 1.06 g/mL. Cherry tomato is suspended in between the water and dish soap.

Predict the density of cherry tomato and explain.

Law of Conservation of Matter

Matter is not created or destroyed in a chemical reaction.
Mass of Reactant = Mass of Product
Mass is in [g]

Multiple Choice

In a reaction A + B ----> C, reactant A has 5g and product C has 9g. How many grams does reactant B should have?

14g

Light Emission

Two process: Absorption, Emission
Absorption: Electron absorbs energy(light/photon) and jumps up from the ground state to the higher energy level to become excited.
Emission: Electron releases energy as a light and jumps back from excited state to the ground state.

Multiple Choice

Emission of light from an atom occurs when an electron

drops from a higher to a lower energy level.

jumps from a lower to a higher energy level.

moves within its atomic orbital.

falls into the nucleus.

Electronegativity [EN]

: atom's ability to attract electrons from other atoms
Fluorine has the highest EN
Noble gases has no value

Multiple Choice

Which has the greater Electronegativity:

N or C?

Predicting the products: Single Replacement

Cation: AB + C --> A + CB
Anion: AB + C --> AC + B
Ionic compound: Cation-Anion
Diatomic atoms: H₂, N₂, O₂, F₂, Cl₂, Br₂, I₂

Multiple Choice

Predict the products for the this Single Replacement reaction:

K + HCl →

KCl + H₂

KHCl

KH + Cl₂

HCl + K₂
