Density/Solubility
If I have a cube with a mass of 1,435 g and a cube of the same material with a mass of 627 g, Which one has more density?
Neither has more density, they each have the same
What are the two main types of bonds
ionic and covalent
what is the charge of a proton and where is it located?
Positive, in the Nucleus
What test uses light to test mineral identity and what are the two major kinds.
Luster, Metallic and Non-metallic
What is the element located in group 11 period 5?
Ag-Silver
Would a metallic ball with a density of 3.21 g/cm3 float in a liquid that had a greater density?
Yes, the liquid would sink and the ball would float
How does a covalent bond work and what kind of elements do you need?
Covalent bonds shared two electrons between nonmetals.
How many electrons can be held on the third electron shell?
18 electrons
What kind of matter does filtration get rid of?
Smaller particles of insoluble matter
What do the elements Neon (Ne) and Xenon (Xe) have in common?
They are located in Group 18 and both are Noble gases.
What is the units that are present on the y-axis of the solubility curve graph?
grams of solute per 100 g of solvent
If I have an atom of carbon-12 and an atom of carbon-13, what is the difference between them and what are those called
They are Isotopes and the difference between them is the number of neutrons
What does the atomic number tell us about an atom?
The number of protons and electrons
What piece of equipment is needed for an extraction?
Separatory funnel
How many Protons and electrons are in a Calcium (Ca) Atom?
20 P & 20 E
If I have solid solute, is the solubility going to increasing or decreasing depending on the temperature?
It would be increasing
What is an Isomer and what is the difference between them?
Isomers have the same parts of a molecule, it is just bonded differently. This gives the molecule different properties.
How do you find the number of Neutrons in a non neutral Atom?
Atomic Mass - Atomic Number = Number of Neutrons
How do you test hardness on the Mohs scale
What does a period on the periodic table tell you about the elements within it?
The number of electron shells present in a neutral atom of that element
A saturated solution is the limit of solute that can be dissolved at a specific temperature while a supersaturated solution can no longer dissolve solute at a specific temperature.
What is the exact charge (+1,-1 etc.) of atom that gives up its electron during an ionic bond?
+1, because it is losing a negatively charged particle and gaining a positive charge.
How does an atom stay held together?
The opposite forces of attraction pull the atom together with the neutrons helping keep the nucleus intact
What property of water is being displayed while using a stick to pour off liquid during a decantation?
Water's Adhesive properties
What is the family of Group 2 on the periodic table called and what is their charge?
Alkaline Earth Metals and they have a 2+ charge when forming ions
