Who got a 5 paragraph sub letter?
Braxton and Anthony
How is density calculated?
density=mass/volume
What is exothermic?
This term describes a chemical reaction that releases energy into its surroundings, often resulting in a temperature increase.
What are carbon dioxide (CO_2) and water (H_2O)?
These are the two primary chemical products of the mplete" combustion of any pure hydrocarbon."co
What is Kelvin?
When using any gas law equation, temperature must always be converted to this absolute scale.
How old is Ms. Cassidy?
29
Which variable must be converted before we can use the combined gas law?
temperature
What is endothermic?
Because it always requires an input of energy to pull atoms apart, the process of breaking a bond is always this type of reaction.
What is carbon monoxide (CO)?
This colorless, odorless, and toxic gas is produced during "incomplete" combustion when oxygen is limited.
200- PV=nRT : What Does it Mean?
Pressure, Volume, Amount, Temperature
Who is the shortest in the class?
Robert
This is the result when you convert 5.0 grams (g) into milligrams (mg).
What is 5,000
What are reactants and products?
Reactants are the starting materials in a chemical reaction, the products are the new substances formed.
What are the ideal chemical products for a gasoline combustion reaction?
Carbon dioxide and water vapor
How can we use the Combined Gas Law to understand pressure changes in the fire syringe?
rapidly decreasing the volume (V) of air increases both its pressure (P) and temperature (T),
Who is never in class?
Lena
Convert 280cm into m.
2.8m
What happens when more bonds are formed?
The bond strength increases.
What is the most likely result of incomplete combustion in an engine?
Formation of carbon monoxide due to a lack of oxygen
What is the role of oxygen in the combustion of a hydrocarbon fuel in a typical engine?
It is the oxidizer (reactant) that allows the fuel to burn.
How many eyelashes does Sam have on each eye.
92
To convert 250 milliliters (mL) into liters (L), you must divide the value by this number.
what is 1,000?
What is Delta H?
The difference in heat energy between the final products and the starting reactants (delta h = H products - H reactants)
What is a catalytic converter?
This device in a car's exhaust system uses redox reactions to convert pollutants like nitrogen oxides and hydrocarbons into less harmful gases.
What is the combined gas laws formula?
p1v1/T1=p2v2/T2
