Name the types of bonds
hydrogen
covalent
ionic
The process that involves the rearrangement of the molecular structure of a substance, as opposed to a change in physical form or a nuclear reaction.
What is a chemical reaction
Reaction where 2 or more substances combine to form a single new substance.
What is synthesis/combination reaction
Distance moved by a particle or body in a specific direction
What is displacement
energy can't be created nor destroyed only transferred
What is 1st law of thermodynamics or the law of conservation of energy?
The bond wherein electrons are given and taken between elements in the compound
Ionic Bond
Reaction where a compound breaks down into 2 or more substances that is endothermic
What is decomposition
Reaction in which one element in a compound replaces a similar element in a compound.
What is single replacement
the measure of energy transfer when an object is moved over a distance by an external force at least part of which is applied in the direction of displacement
What is work
The range of possibilities of arrangements in a system; also known as "chaos"
entropy
When elements form a weak bond between each other from an attraction to electrons leading to the molecules having differing polarity as one molecule draws the electrons away from the other molecules.
What is hydrogen bond
When energy is released during a reaction
exothermic
Reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat. Exothermic
Combustion
What is potential energy
The entropy of a system is always increasing
What is the second law of thermodynamics
H2O is an example of this bond; the electrons are shared
covalent bond
When energy is required for a reaction to occur
endothermic
Reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds.
Double Replacement
Once a tennis ball is tossed in the air, it's movement upward is which type of energy?
Kinetic energy
If 2 thermodynamic systems are in thermal equilibrium with a third system separately, then they are in thermal equilibrium with each other.
What is the zeroth law of thermodynamics
In water, Oxygen has a partial negative charge while the Hydrogens have a partial positive charge. What is the name of this partial charge?
Polarity
How many types of reactions are there?
6
When an acid and a base are combined, water and a salt are the products. Salts are ionic compounds containing a positive ion other than H+ and a negative ion other than the hydroxide ion, OH− . Double displacement reactions of this type are called neutralization reactions.
