Answer:
2.895*10^24
Explanation:
mass of Oxygen give = 153.9g
molar mass of O2 molecule = 16*2=32g/mol
n= mole
To find the mole
n= mass/ molar mass
n= 153.9/32
n=4.81mol.
To find the number of molecules of o
Nm= number of molecule
Nn = Number of mole
NA = number of Avogados
Nm= Nn * NA
Nm= 4.81 *6.02*10^23
Nm= 2.895*10^24
The chemical property of soda is that it is a highly basic substance. Its chemical name is sodium carbonate. It is more basic than sodium bicarbonate. Adding soda ash in a solution would increase the pH of the solution.
No, the solid can not be frozen water. This is because water has a melting point of 32 degrees Fahrenheit. Room temperature is well above 32 degrees, so the solid would have begun to melt. Since the solid was not melting, we can infer that it is not water.
Answer:
the answer is a because cirrus clouds have that definition
This is true because the most accurate slope of the line would be given by the points that either reside on the line or close to it.
