Equipment/Lab Safety
Name the lab equipment that measures volume and the lab equipment that measures mass.
What is graduated cylinder & triple beam balance
Label the correct units for mass, time, and length.
What is grams (g), seconds (s), and meters (m)
Draw out the density triangle, what is the equation for density?
What is D=m/v
Define Physical & Chemical Changes
What is
P - reversible, observable, measurable processes. Identity remains
C - irreversible, new properties are created, chemical reaction took place.
Classify "Nitrogen" as an element, compound, homogenous mixture or heterogenous mixture
What is element
In the Physical and Chemical changes lab it was stressed that all reactions occur within this piece of lab equipment. Name and describe that piece of equipment.
What is test tube. Narrow, no volume markings, solely for reactions, made of pyrex glass, etc
Convert 500 meters to km
What is 0.5 km
The graduated cylinder has 6.80 mL of water in it. A sample is dropped into the cylinder and the level rises to 8.20 mL. What is the volume of the sample
What is 1.40 mL. 8.20 mL - 6.40 mL
Metal Rusting (C or P)
What is Chemical, metal oxidizes
Classify "Sodium Chloride (NaCl)" as an element, compound, homogenous mixture, or a heterogeneous mixture
What is compound.
Name the differences between a beaker and graduated cylinder
What is beakers hold a larger volume than grad cyl. however, grad cyls are more precise than beakers are. If I want about 50 mL I will use beaker (accurate) If I want 36 mL exactly, I use grad cyl. (precise).
What is 2.5 g
Based on the definition of matter, what is the difference between mass and volume.
What is:
Matter- anything that has mass and takes up space
mass is the amount of matter, volume is the amount of space
Grounded red powder (C or P)
Classify "coffee" as an element, compound, homogenous or heterogenous mixture.
What is Homogeneous mixture
Name this piece of lab equipment. Has thin neck but wide base and some volume markings
What is Erlenmeyer flask
A platinum bar measures 5.0 cm x 4.0 cm x 2.0 cm. It has a density of 17.5 g/cm^3. Find mass
What is 700g
Object containing mass (P or C)
Two types of Matter, What categories are they broken up into
What is pure substances and mixtures. Pure substances are elements and compounds. Mixtures are homogeneous and heterogeneous.
Walk me through how to ignite the bunsen burner. Go through safety precautions as well as how to change the height and heat output of the flame.
What is hair tied back, loose clothing tucked away, goggles, apron, turn on gas source, plug in bunsen burner, turn on gas, strike the bunsen burner, turn the neck counter clockwise for more heat (lighter flame) turn the gear at the base to change the height of the flame.
Convert 1.2 km to mm
What is 1,200,000 mm
A sample has a mass of 1.425 kg and a density of 9.56 g/mL. Find Volume
What is 149.06 mL
I have a piece of paper, give an example of a physical and a chemical change that could be done to the paper
What is
P- crumbling or tearing it up
C - setting it on fire
Having a set formula and only being able to be separated by chemical means would be criteria to fit into this category of matter.
What is a pure substance
