Answer:
Conversion factor is 6.022 ×10^23 molecules/mole.
Number of moles is 5.845 moles
Explanation:
We are given;
3.52 × 10^24 molecules
Required to determine the conversion factor\
We know that according to the Avogadro's constant;
1 mole of a compound contains 6.022 ×10^23 particles
Therefore, 1 mole of a molecular compound contains 6.022 ×10^23 molecules.
Thus, the conversion factor in this case would be 6.022 ×10^23 molecules/mole.
Such that; 3.52 × 10^24 molecules are equivalent to;
= 3.52 × 10^24 molecules ÷ 6.022 ×10^23 molecules/mole.
=5.845 moles
Thus, the conversion factor is 6.022 ×10^23 molecules/mole.
Number of moles is 5.845 moles
The statement labeled as (a) is the correct one on that list.
Answer:
B) K2X
Explanation:
In an uncharged compound, the total oxidation state must be zero. The oxidation state of the calcium is +2, thus we get the following formula, where x is the oxidation state of the polyatomic ion X:
Also, it is known that potassium has an oxidation state of +1. Since the new compound also has a total oxidation state equal to zero, we get the following equation, where k is the number of K atoms:
That's how it is found that the compumd consists of 2 K+ ions and one X ion.
No, a precipitate will not form when barium nitrate, Ba(NO3)2, reacts with potassium hydroxide, KOH, in aqueous solution because both products are soluble in water.
