Answer:
A. Distance from the moon.
Answer:
Dissociation factor = 1.8
Explanation:
Data provided in the question:
Molecular weight of the Procaine hydrochloride = 273
Number of ions contained, n = 2
Fraction Dissociating, α = 80% = 0.8
Now,
the dissociation factor 'i' is given as:
i = 1 + α × ( n - 1 )
on substituting the respective values, we get
i = 1 + 0.8 × ( 2 - 1 )
or
i = 1 + ( 0.8 × 1 )
or
i = 1.8
Yes, she is right. 1: when she took them out of the freezer heat was added. 2: when she toasted them in the oven heat was added and a chemical change occurred because the baking soda/powder reacted, causing the muffins to rise.
To answer this question, we'll need the molar masses of nickel and vanadium:
Molar mass of nickel: 58.693g/mol
Molar mass of vanadium: 50.941g/mol
These values represent the mass of one mole of the element. A mole is the weight of Avogadro's number of atoms of an element (6.02 x 10^23 atoms).
We are given 58.693g of nickel, which is equivalent to one mole of nickel. Therefore, you will get the same number of atoms from one mole of vanadium, or 50.941g of vanadium.
