Molecular Structure
A group of atoms that are held together by chemical bonds and act as a unit.
Molecules
Characteristics that you can observe or measure without changing the identity of the matter are__________________________?
Physical Properties
The ability of a type of matter to burn easily.
Flammability
This occurs when atoms of one or more substances rearrange to form one or more new substances.
Chemical Reactions
Chemical reactions where more energy is required to break the bonds of reactants than is released when products form.
Endothermic Reactions
You are given a sample of an element, it is shiny and can be hammered into a sheet. What kind of element is it?
Metal
The amount of matter in a substance.
Mass
This occurs when substances react with oxidizing agents, changing it to a new substance.
Oxidation
This states that the total mass before a chemical reaction is the same as the total mass after the chemical reaction.
The Law of Conservation of Mass
When this happens, more energy is released when the products form than is required to break the bonds in the reactants.
Exothermic Reactions
You are given a sample of an element, it is dull and brittle. What kind of element is it?
Non-metal
The amount of space a substance takes up.
Volume
This occurs when a substance reacts with another substance, changing i to a new substance.
Reactivity
The starting substances in a chemical reaction.
Reactants
This states that even though energy is always transferring, energy is not created and energy is not destroyed.
Law of Conservation of Energy
Is sugar an ionic or covalent compound?
Covalent
The mass per unit volume of a substance.
Density
The ability of matter to conduct electricity or thermal energy.
Conductivity
The substances produced by the chemical reaction.
Products
Endo means?
In
If a molecular compound dissolves well in water, do you expect it to be polar or nonpolar?
Polar
Density Equation: D=m/v
An object has a mass of 50 grams and a volume of 5 milliliters. What is the density of the object?
10g/ml
The ability of a substance to dissolve in another substance is solubility.
Solubility
A number placed in front of an element symbol or chemical formula in an equation.
Coefficient
Exo means?
