The ideal gas law is presented
by the equation PV = nRT. n, the number of moles, is equal to mass over molar
mass. And density is M/V.
PV = nRT
PV = (M/molar mass)RT
P/RT = (1/molar mass)(M/V)
M/V = D = (molar mass)(P/RT)
Molar mass of CO2 = 44 g/mol
D = (molar mass)(P/RT)
D = (44 g/mol)(1 atm)/(0.08206
L-atm/mol-K)(273K)
D = 1.964 g/L
Answer:
decreases
Explanation:
warm water hold less dissolved oxygen than cold water because the molecules are moving faster.
Answer:
They have one overall charge
Explanation:
Negative or positive
Answer:
Answer D. Picture II shows a chemical change, because the same substance changes form
Explanation:
This is the temperature that water molecules slow down enough to stick to each other and form a solid crystal
Answer:
Independent Variables
Explanation:
These are changes that are made by the experimenter. They are factors that one is able to manipulate or control their values.
