what term describes the amount of energy required to break one mole of a specific chemical bond in the gas phase.
bond energy
what gas, which makes up about 21% of Earth's atmosphere, must always be present for a combustion reaction to occur.
oxygen
According to Boyle’s Law, if you squeeze a gas into a smaller container (decreasing its volume), this will happen to the pressure of the gas.

When a hydrocarbon fuel burns completely, what are the two primary chemical products released into the air
carbon and water
Leaving a basketball outside on a freezing cold night causes it to deflate slightly. This is an everyday example of this scientist's volume-and-temperature law.

Convert 4.5 grams into milligrams (mg).
4,500
This type of strong chemical bond is formed when two atoms share electrons.
covalent bond
Unlike gasoline engines which use a spark plug to ignite fuel, diesel engines rely entirely on this physical process to heat the air enough to cause ignition.
compression
This variable describes the amount of three-dimensional space that a gas fills up, usually measured in Liters or milliliters.
volume

A single molecule of carbon dioxide contains this total number of atoms.
3
what type of chemical bond is formed when one atom completely gives away an electron to another atom, creating attracted opposite charges.
ionic bond
This is the primary type of energy stored within the chemical bonds of fuel before it is burned in an engine.
potential energy
This variable describes the push or force that gas particles exert when they collide with the walls of their container.
pressure
how many dreads does travis have
125
To convert any measurement from a larger unit to a smaller unit (for example, converting meters to centimeters), you must perform this basic arithmetic operation.
multiplication
what type of covalent bond involves the sharing of exactly four electrons (two pairs) between two atoms.
double bond
This greenhouse gas is the primary byproduct of burning fossil fuels in cars and factories, and it plays a major role in trapping heat in Earth's atmosphere.
carbon
This variable is a measure of how fast the particles of a gas are moving. The faster they move, the higher this goes.
temperature
