Answer:
Climate is long time intervals and weather is short time intervals
Explanation:
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
this equation does support the law of conservation of mass.
19) it's not balanced because when adding h2 and o2 u get h2o2 not h2o
20) I'm not sure
