Answer:
The answer to your question is V2 = 825.5 ml
Explanation:
Data
Volume 1 = 750 ml
Temperature 1 = 25°C
Volume 2= ?
Temperature 2 = 55°C
Process
Use the Charles' law to solve this problem
V1/T1 = V2/T2
-Solve for V2
V2 = V1T2 / T1
-Convert temperature to °K
T1 = 25 + 273 = 298°K
T2 = 55 + 273 = 328°K
-Substitution
V2 = (750 x 328) / 298
-Simplification
V2 = 246000 / 298
-Result
V2 = 825.5 ml
The best diagram to represent N2O is the second diagram.
The Lewis diagram is used to represent the way two or more atoms bond. This is possible by using lines to represent bonds and dots to represent electrons.
In the case of the molecule N2O bonding occurs in the following way:
- A triple bond is formed between the nitrogen atoms, which means, in the Lewis diagram the nitrogen atoms are connected with three lines.
- The oxygen atom connects to one of the nitrogen atoms.
- The nitrogen atom that is not connected to the oxygen will have 2 electrons represented by dots because the number of valence electrons is 5, but three were used in the triple bond.
- The oxygen atom will have 6 electrons represented by dots, which are equal to the number of valence electrons.

A physical change in a substance doesn't change what the substance is. In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
Hopefully that helps you ❤
I found another question like this. Someone answered "The best answer to this question is adding a catalyst.
Adding a catalyst will cause the greatest increase in the rate of reaction for this chemical reaction , 8Zn(s) + S8(s) 8ZnS(s). ---> adding a catalyst always affects the rate of a reaction."
Yes this is true otherwise it would not be a solution
