is slater todds mustache real
no
In the metric system, this is the basic unit used to measure mass.
gram
In any chemical reaction, breaking bonds is always ______, while forming bonds is always ______.
Endothermic (requires energy); Exothermic (releases energy).
To create a combustion reaction in an engine, you need these three specific things
fuel source, oxygen, ignition spark
What is combined gas law
It is the law of the ration of pressure and volume to the absolute temperature of a gas as a constant (this is the google definition might be a little overkill)
how old is slater todd
21
If you are converting from kilometers to meters, you would multiply the number of kilometers by this value.
1000
Rank these three types of covalent bonds between the same two atoms from lowest bond energy to highest bond energy: Double, Single, Triple.
Single < Double < Triple. (Triple bonds are the strongest and hardest to break)
Combustion is a process that converts Chemical Potential Energy stored in fuel into these two other forms of energy to move the car.
thermal anergy, and kinetic energy
what unit is temperature in in the formula
kelvin
where is slater todd from
cali
This is the temperature scale used in chemistry that starts at absolute zero; you find it by adding 273.15 to the Celsius temperature
kelvin
calculate the total Enthalpy Change ($\Delta H$) of a reaction using bond energies, do you subtract "Products minus Reactants" or "Reactants minus Products"?
Reactants minus Products.
In a four-stroke engine, this specific stroke follows "Compression" and is the only stage where work is actually produced by the expanding gases
What is the Power Stroke
true or false pressure and temperature are directly related
true
slater todds favorite activity
being on the beach and swimming seeing the dolphins
his value, found on the Periodic Table, tells you how many grams are in one mole of an element, allowing you to convert between mass and particles.
molar mass
If the energy required to break the reactant bonds is greater than the energy released when the product bonds form, is the reaction exothermic or endothermic?
Endothermic
This dimensionless value represents the ratio of the air-to-fuel mixture in a combustion chamber relative to its stoichiometric ideal; a value less than 1.0 indicates a "rich" mixture
While many use "Air-Fuel Ratio," Lambda is the specific term used for the ratio relative to stoichiometry.
true or false scuba divers use combined gas law
true
what does slater todd do on shifts
people watch
This property is defined as mass per unit volume (like g/mL); to convert it, you often have to use a "triangle" formula to find one of the three missing variables.
Density
On a Potential Energy diagram, if the "product" line is lower than the "reactant" line, what does this tell you about the strength of the bonds in the products compared to the reactants?
The bonds in the products are stronger
Most modern cars use this "multi-port" system to spray finely misted fuel directly into the air stream or cylinder, replacing the older carburetor
What is Fuel Injection
what scientist founded the combined gas law
Boyle, Charles, and Gay-Lussac
