States of Matter
This state of matter represents the most tightly packed a substance can be.
What is solid?
This equation is also what is meant by "Mr. Davis loves you."
These are the two subatomic particles found in the nucleus.
What are protons and neutrons?
This number on a periodic square tells us the number of protons in the element.
What is the atomic number?
This is the portion of a solution that gets dissolved.
What is a solute?
Oxygen, methane, and carbon dioxide are all examples of molecules that are typically in this state of matter.
What is gas?
If an object is less dense than water, it will typically do this when placed in water.
What is float?
These subatomic particles carry a negative electric charge.
What are electrons?
This element is the only element to typically not have any neutrons in its nucleus.
What is hydrogen?
This is the process of one substance breaking down another substance in a solution.
What is dissolving?
Ice skating is only possible when bodies of water do this phase change.
What is freeze?
These are generally used to measure the volume of liquids.
What are graduated cylinders?
H2, O3, and N2 are all examples of this.
What are molecules?
Fe is the chemical symbol for this element.
What is iron?
Saltwater uses salt as this kind of part to the solution.
What is a solute?
When water vapor in clouds bunch up and become rain, this phase change occurs.
What is condensation?
When I cook with olive oil, 100 milliliter has a mass of roughly 90 grams. This would be the density of olive oil.
What is 0.9g/mL?
More complex chemical structures like CO2 and glucose (C6H12O6) are all examples of this.
What is a compound?
This group on the periodic table is also known as the "inert gases."
What are the noble gases?
These bonds get broken when salt is added to water to make saltwater.
What are ionic bonds?
Dry ice becoming carbon dioxide gas is an example of this kind of phase change.
What is sublimation?
Silver has a density of 9g/cm3. If I had 200cm3 of silver, it would have this much mass.
What is 1800g?
Many salts form when an alkali metal (like sodium or potassium) bonds with a halogen (like chlorine or iodine), forming this kind of bond.
What is an ionic bond?
Both of these elements typically have 14 neutrons, but they have different number of protons.
What are aluminum and silicon?
Solid tin is added to molten copper to make bronze, making copper this in a solution.
What is a solvent?
