Answer:
Mass = 25.08 g
Explanation:
Given data:
Volume of fluorine = 29.6 L
Temperature = standard = 273.15 K
Pressure = standard = 1 atm
Mass of fluorine = ?
Solution:
The given problem will be solve by using general gas equation,
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
n = PV/RT
n = 1 atm × 29.6 L / 0.0821 atm.L/ mol.K × 273.15 K
n = 1.32 mol
Mass of fluorine:
Mass = number of moles × molar mass
Mass = 1.32 mol ×19 g/mol
Mass = 25.08 g
Answer:
The cells differentiate.
Explanation:
Organism can be simply classified on the basis of the cellularity of the organism. Two main types of organism are unicellular organisms and the multi cellular organisms.
Multicellular organism contain different types of cells. The different cells differentiate to perform a particular function. The division of labor property is well shown by the multi cellular organism. The cells of the multi cellular organism must show differentiation process.
Thus, the correct answer is option (d).
A) electrolyte the others either describe a process, the opposite, or a whole different thing
Covalent bond is the type of bond which involves the sharing of valence electrons between two atoms.
This bond usually arises from the equal attraction of the nuclei of the two atoms for the electrons shared.
Ionic bond, on the other hand, arises due to the transfer of electrons from the valence shell of one atom to the valence shell of the other.
Earthquakes may lead to
a) damage to buildings / houses
b) Tsunami
c) Damage to electricity supply
d) Life threatening Harm to animals
e) Life threatening harm to humans
