This is the definition of bond energy.
the amount of energy required to break a specific chemical bond in one mole of molecules
These are the two primary products of the complete combustion of a hydrocarbon.
CO2 and H2O
A gas has a volume of 2L at 1 atm and 300K. If pressure increases to 2 atm and temperature stays at 300K, what is the new volume?
1L
Oyster shells are primarily made of this chemical compound, also found in chalk and limestone.
Calcium Carbonate
How many grams are in 0.5 kilograms?
500 g
Is bond breaking an endothermic or exothermic process
endothermic
This gas is required as a reactant for any combustion reaction to occur
O2
In gas law problems, temperature must always be converted to this unit.
Kelvin
As ocean acidity increases, the concentration of this ion decreases, making it harder for oysters to build shells.
Carbonate ion
Convert 25 celcius to Kelvin
298.15 K
Which is stronger and has higher bond energy: a C=C double bond or a C-C single bond?
C=C double bond
In an internal combustion engine, this stroke follows the intake stroke
compression stroke
If you double the temperature and double the pressure of a gas, what happens to the volume?
Volume stays the same
Calculate the molar mass of Calcium Carbonate
100.09 g/mol
If a substance has a density of 2 g/mL, what is the volume of 10 grams of that substance?
5 mL
Why do atoms form chemical bonds in terms of energy?
To reach a lower, more stable potential energy state
This is the term for "incomplete" combustion that produces a deadly, odorless gas.
Carbon Monoxide
A balloon at 1 atm and 273K has a volume of 10L. What is the volume at 2 atm and 546K?
Oysters are "filter feeders." A single adult oyster can filter approximately 50 gallons of water per day. How many gallons can a reef of 1,200 oysters filter in one day?
60,000 gallons
Convert 5.0 moles of Carbon to atoms
$3.01 x 10^24 atoms.
If the total energy of the products is lower than the reactants, the reaction is this.
exothermic
What is the spark plug's role in a car engine?
To provide the activation energy needed to ignite the fuel-air mixture.
This law states that at constant temperature, pressure and volume are inversely proportional.
Boyle's Law
If an oyster reef removes 5 grams of nitrogen from the water per oyster per year, how many kilograms of nitrogen are removed by a reef of 2,000 oysters?
10kg of nitrogen
