Answer:
K3[Al(C2O4)3] is the answer
Answer:
a. 4
Explanation:
The number of theoretical plates is the number of discrete distillations that would have to be performed to obtain an equivalent separation of a discrete plate. This number is commonly used as a measure of separation efficiency and is a useful when comparing the performance of various chromatographic columns.
One theoretical plate is equivalent to one vaporization-condensation cycle, which is equivalent to one simple distillation. Thus a fractionation column that can attain the equivalent of three simple distillations would be said to have three theoretical plates.
Let us assume that this molecule is 100 percent ionic. In that case, the charges are distinguished by a bond length.
h = Q × r
= (160 × 10⁻¹⁹ c) (127 × 10⁻¹² m) (10 / 3.336 × 10⁻³⁰ cm)
= 6.09 D.
The actual dipole moment is = 1.08 D
Therefore, the percent ionic character is,
= 1.08 D / 6.09 D × 100
= 17.7 %.
Answer:
B. Density
Explanation:
Density is the only property of liquid in the option that is feasible.
Water has no form of magnetism as it’s not a magnetic substance.
Water carries the size of the container it is put into and has no definite shape.
Water’s boiling point can only be gotten when it’s heated and it’s known to be mostly 100 degree celsius when pure and may be more or less depending on the level of impurities.
However Density is the mass per volume of water and can be calculated before the noodle is cooked which is more effective in its differentiation.
Explanation:
The potassium fluoride will dissociate into potassium ions and fluoride ions in their aqueous solution.
So, when 1 mol of hexaaqua aluminium (III) reacts with 6 moles of fluoride ion it gives 1 mole of hexafluoroaluminate(III).
The reaction is given as:
