What is the difference between a homogeneous mixture and a heterogeneous mixture? Give an example of each.
The difference between homogeneous and heterogeneous mixtures is that a homogenous mixture will have the same composition throughout and a heterogeneous mixture has a different composition throughout.
Examples may vary
What's the name of the branch of science that studies the solid materials and structures of the earth?
Geology
What is the name of the branch of science that studies what takes place outside of Earth’s atmosphere?
Astronomy
Anything that has mass and volume. It is the “stuff” that all physical objects are made of.
Matter
An atom that has an unequal number of electrons and protons.
Ion
What is the difference between a substance with high density and a substance with a low density?
High density substances have their atoms arranged closer together than substances with a lower density.
Substance made of only one type of atom.
Element
An atom that has more or less neutrons.
Isotope
The smallest particle of a compound that still has its properties.
Molecule
Stable gasses that are very unreactive due to the fact they have full sets of their outermost valence electrons.
Noble gasses
Reactions in which heat is absorbed.
Endothermic
A mixture with the same proportion of substances throughout.
Homogeneous mixture
A bond where atoms share one or more of their outermost valence electrons.
Covalent bond
When substances combine but not in any specific proportions.
Mixture
Reactions in which heat is created.
Exothermic
The grouping of elements according to their properties developed by Dmitri Mendeleev.
Periodic table
A mixture with different proportions of substances throughout.
Heterogeneous mixture
The portion of a mixture that is dissolved in the liquid.
Solute
The liquid portion of a solution in which other substances are dissolved into.
Solvent
Original substances that interact with each other in chemical reactions.
Reactants
What chemical bonds hold water molecules together? How are these bonds different than other chemical bonds?
Water molecules are connected to each other in short lived bonds called hydrogen bonds. Because they are so short lived, water remains a liquid but at any given time many of the water molecules are bound to each other it creates surface tension.
