Lab Safety/Equipment
The four things you need to be wearing in lab
What is lab coat, goggles, gloves, and closed toed shoes?
The shape of a solid
What is rigid?
What is an element?
A non-uniform mixture where the components are not evenly distributed and different components are easy to see or separate out over time.
What is a heterogeneous mixture?
The phase change from a solid to a liquid
What is melting?
The difference between a pipette and a dropper
What is a pipette is more accurate/precise?
The particles of gases look like this
What is moving quickly and in all different directions?
The classification of trial mix
Heterogenous mixture
Is a combination of two or more substances (elements, compounds, etc) that are physically combined.
What is a mixture?
The phase change from a liquid to a gas
What is evaporation?
The difference between an erlenmeyer flask and a beaker
What is a skinny neck flask vs a wide mouth beaker?
What is solidification/hardening?
The classification of oil and water
Heterogenous mixture
The simplest form of matter that is composed of a single type of atom. It can not be separated or broken down by physical or chemical means.
What is an element?
The effect of increased pressure on a liquid
What is phase change to a solid. The particles are pushed together to from a solid.
The property name for "there is no change in the total amount of matter when you matter is converted from one type to another"
What is the Law of Conservation of Mass?
The classification of pure air
What is homogenous mixture?
Formed when two or more different elements chemically combine with a bond and in fixed proportions.
What is a compound?
We can add these three things to a system to induce a phase change
What is heat, cold, and pressure?
The purpose of a test tube
What is to hold small chemical reactions and NOT to measure.
This can occur when the sample is composed of many small pieces
What is some samples of matter appear to have properties of solids, liquids, and/or gases at the same time?
The classification of NaCl (table salt)
What is a compound?
Elements that are stable as two of the same atom bonded together.
What is a diatomic element?
The phase change from a solid to a gas?
What is sublimation?
