Answer:
Mendeleev arranged the elements on the first periodic table by Increasing atomic mass
Answer:
Molality = 0.33 mol/Kg
Explanation:
Given data:
Volume of solvent = 2.00 L
Mass of solute = 225 g
Molality of solution = ?
Solution:
Formula:
Molality = Number of moles of solute / kg of solvent
Now we will calculate the moles of solute.
Number of moles = mass/ molar mass
Number of moles = 225 g/ 342.3 g/mol
Number of moles = 0.66 mol
Now we will calculate the Kg of solvent.
1 L = 1 Kg
2 L = 2 Kg
Molality = Number of moles of solute / kg of solvent
Molality = 0.66 mol / 2 kg
Molality = 0.33 mol/Kg
Answer:
B
Explanation: because it is most likely to be warm in summers and cool in winters in temperate zones
Answer:
Laws of Nature are to be distinguished both from Scientific Laws and from Natural Laws. On the other account, the Necessitarian Theory, Laws of Nature are the principles which govern the natural phenomena of the world. That is, the natural world “obeys” the Laws of Nature.
A. Both the cell membrane and the nuclear membrane are protective coverings.
