Answer:
Polarizing Power is the basis of Fajan's rules of covalent character generally in ionic compounds.
Charges and radius are a function of Polarizing Power, because the higher the charge is, the larger the polarizing power is for cations with the same radius. Also the smaller the radius is, the larger the polarizing power is for cations with the same charge.
Explanation:
Answer:
Once the sun comes up, the sunlight excites the cold air in the first foot or so above the ground (which can be 10 or more degrees colder), which causes it to move around and mix into the next several feet of air. That “mixing upward” drops the temperature of the air at thermometer level.
Explanation:
Answer:
<u>Ruler A
:</u>
According to ruler A, the diameter of the circle has only one certain digit and one uncertain digit. if we look at measurement of a diameter, it contain two significant figures. so the certainty of the diameter measurement is <em>smaller.
</em>
<u>Ruler B
:</u>
According to ruler B, the certainty of the diameter measurement is <em>greater. </em>because it contain two certain and one uncertain digit. it has three significant figures.
Chemistry is really a normal thing to do with two plus two
The final volume of the unknown gas is 787.5 ml
Given:
volume of unknown gas = 450.0 mL
initial pressure of unknown gas = 0.07 atm
final pressure of unknown gas = 0.04 atm
To Find:
final volume of the unknown gas
Solution:
Substituting these values into Boyle’s law, we get
P1V1 = P2V2
(0.07)(450) = (0.04)V2
V2 = (0.07)(450)/(0.04)
V2 = 787.5
So, final volume of the unknown gas is 787.5 ml
