Did you know?
What two chemists created the two fundamental gas formulas that when combined become the combined gas law?
What is polarity?
Polarity is when a molecule has an uneven distribution of charges within the molecule, but maintains a net neutral charge.
A Universal Solvent.
What is water?
What drives all chemical reactions?
Electron movement in the form of transfer or sharing.
Credited with putting together the Periodic Table of Elements.
Who is Mendeleev?
Moles per liter.
What is molarity?
Amount of space something occupies.
What is volume?
How many elements are in the present day periodic table?
118
What are the three subatomic particles that make up an atom and where are they found in the atom?
Protons, Neutrons, and Electrons.
What is atomic mass? And what are the units we measure this in?
Atomic mass is the mass of an element and the units these are measured in are the amu or atomic mass unit.
Salt would be called *____* in a solution?
What is a solute?
How can we determine what charge ions will be formed when combined?
It will depend on how many valence electrons are present in an unreacted element.
How is an ionic compound made and what is formed when these bonds occur?
Ionic compounds are made by reacting a metal with a non-metal. Ions are made when this occurs.
What is the formula for density?
Density=mass/volume
a substance consisting of two or more substances mixed together and uniformly dispersed, most commonly the result of dissolving a solid, fluid, or gas in a liquid
What is a solution?
Describe the trend of the pH scale.
Elements between zero and 6.99 are acidic, 7 is neutral, 7.01-14 are basic.
Describe the reactive behavior of noble gases and why.
They are virtually nonreactive because their valence shells are full.
Elements found in sugar?
What are carbon, hydrogen, and oxygen?
Calculate the molar mass of sodium chloride.
58amu
What is calorimetry?
The science of measuring the heat transferred two or from a substance during physical changes or chemical reactions.
What is a neutralization reaction?
A chemical reaction where an acid and a pace react to form water and a salt. The reaction results in a neutral solution.
What is the most electromagnetic element on the periodic table?
Flourine
