Answer: Strong bases are good electrolytes because they completely ionize in water.
Explanation:
Weak bases are those substances which dissociate partially to give ions when dissolved in water.
Strong bases are those substances which dissociate completely to give ions when dissolved in water.
Strong bases are good electrolytes as they completely dissociate to give ions which help in the conduction of electrical current.
B) Repeated experiments that show the same results are less likely to contain experimental errorli
Answer:
malleable, shiny, hard and good electricity conductors
Explanation:
(a) As per the mole concept, one mole of any atom contains atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of = molecules
= molecules
1 mole of = molecules
= molecules
1 mole of = molecules
= molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of contains 2 atoms of hydrogen.
So, mass of 1 mole of =
= 2.016 g
mass of 1 mole of =
= 31.996 g
mass of 1 mole of =
= 37.996 g
Thus, we can conclude that has the greatest mass.
