Periodic Table
The Periodic Table groups this into groups to classify them. What does it group?
Elements
Malleability is what kind of property?
Physical
Describe the difference between a homogenous and heterogenous mixture.
Homogenous mixtures particles are evenly distributed throughout the substance, where heterogenous particles clump together.
What is a solution?
A Homogenous Mixture, where a solute dissolves into a solvent.
50 g of metal moves about 25 ml of water, what is the metals density?
2 g/ml
On the Periodic Table Rows are known as ...
Periods
Chemical Properties correspond with what kind of changes.
Chemical Changes or Chemical Reactions.
What is settling and how does it relate to suspensions?
The large particles in a suspension actually will separate from the mixture on their own in a gravitational field given enough time. (The sand will sink to the bottom) We call this settling.
When a solution is unfull we call it ...
Unsaturated
Transferring heat through touch or direct contact is known as ...
Conduction
On the Periodic Table Columns are known as ...
Groups or Families
What is the difference between extensive and intensive properties?
Extensive properties depend on the amount of substance you have, where intensive properties are unique to the element or compound in question.
Suspensions, Colloids, and Solutions
When a solution is overly flowing with solute and is unstable we call it ...
Supersaturated
What is the volume of an object with a density of 10 g/ml and a mass of 100 g?
10 ml
On the Periodic Table Groups or Families are represent ...
Chemical Properties.
What is Density? Be sure to include what kind of property it is.
Density is a intensive physical property of elements that tells you how tightly the atoms in a substance are packed together. Meaning how much mass per that amount of volume or space taken up.
Describe how you would tell the difference between a colloid and a solution.
The colloid may have color, or not be transparent. But whether the particles inside the mixture are large enough to reflect light (Tyndall's effect) is the ultimate test whether something is a colloid or solution.
Generally to get a solution to hold more solute how should you change the temperature?
You should increase the temperature.
0 Degrees Kelvin represents what ...
Absolute zero the point we cannot reach but is when all the movement of the atoms would stop.
What is the meaning of the word Period as used on the periodic table?
Periods are the amount of time until something repeats. On the periodic table its the amount of elements until the chemical properties repeat.
Describe how to prove the existence of a chemical property of some substance.
You must force the substance to undergo the chemical reaction related to that property, losing the property in the process.
What are the 4 key differences between compounds and mixtures.
Compounds are chemically bonded, have a fixed ratio, have unique properties compared to the constituents or things that make them up, and they cannot be physically separated. None of this is true for mixtures.
Describe how to make a super saturated solution.
You must fill the solution with solute why it is hot and then cool it down such that's solubility curve lowers and it is holding more than it should.
Water’s melting point is 0 degrees Celsius. At this temperature, heat is added to an ice cube, what happens to its temperature?
It doesn't change until the ice cube melts
