Looking at this equation P= (pa*pb)/ (pa+(pb-pa)) ya where pa=vap press a and ya= vap composition a and P= total pressure,it relates vapor pressure mixture to vapor composition. This is derived using the combination of Dalton's and Raoult's laws.
Answer:
None of the Above
Explanation:
The Athenosphere is able to flow but is also part of the UPPER LAYER meaning none of these choices are correct
Answer:
b
Explanation:
A pure substance has a constant composition and cannot be separated into simpler substances by physical means. There are two types of pure substances: elements and compounds.
Using the base dissociation constant for H2PO4, see attached document.
Answer:
2 g/cm3
Explanation:
Density:
we know that density of an object can be measured by dividing its mass to its volume.
Symbol:
The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.
Units:
SI unit of density is Kg/m3.
Other units are given below,
g/cm3, g/mL , kg/L
Formula:
D=m/v
D= density
m=mass
V=volume
Given data:
mass= 10 g
volume= 5 cm3
density= ?
Now we will put the values in the formula,
d= 10 g/ 5 cm3
d= 2 g/cm3
The density of object is 2 g/cm3.
