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
Answer:
B) flat trigonal
Explanation:
All the Hydrogen atoms are arranged symmetrically around the Nitrogen atom which forms the base, and the two nonbonding electrons form the tip
Because they have different boiling points
Answer:
B
Explanation:
A is not the answer. Although the statement is accurate in regards to gases, it does not explain why liquids and gases can flow.
B is the answer. Solids are in fixed structures. When you apply heat or pressure, these structures are broken apart and allowed to move freely.
C is not the answer. This is inaccurate. Changing the phase of a substance does not change the size of the particle.
D is not the answer. The opposite of this statement is true. The attractive forces between particles in a solid allow the substance to hold its structure. When you apply heat or pressure, the attractive forces are overpowered and the structure is broken.
