15. To draw the Lewis structure of the polyatomic ion, ClO3you would have to _____ those in thestructures of Cl, O, O, and O.a.
1 answer:
To draw the Lewis structure of the polyatomic ion, you would have to add one electron to those in the structures of Cl, O, O and O.
Answer: Option A
<u>Explanation:</u>
It is a kind of representation of electrons present in valence shell of each element. For easy understanding of how the outermost electrons will be arranged for bonding purpose, Lewis structure is used.
As we know that carbon has an outermost electron number of 4. So 4 electrons are required as the electrons in the outermost shell of each carbon. But here only three electrons are there, so one electron need to be added in the Lewis structure of .

Answer:
The final temperature was 612 °C
Explanation:
Charles's law relates the volume and temperature of a certain amount of ideal gas, maintained at a constant pressure, using a constant of direct proportionality. In this law, Charles says that at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. That is, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:
When you want to study two different states, an initial and a final one of a gas and evaluate the change in volume as a function of temperature or vice versa, you can use the expression:
In this case:
- V1= 5.76 L
- T1= 22 °C= 295 °K (Being 0°C=273°K)
- V2=17.28 L
- T2=?
Replacing:
Solving:
T2= 885 °K = 612 °C
<u><em>The final temperature was 612 °C</em></u>
