D. The total number of valence electrons is 8 and D represents that. D also correctly uses the octet rule for N and duet rule for H.
Answer:
Characteristic of a substance that Cannot be observed without altering the identity of the substance.
Explanation:
A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points.
Answer:
Final volume, V2 = 13.18 Liters
Explanation:
<u>Given the following data;</u>
Initial volume = 9.9 L
Initial temperature = 303 K
Final temperature = 403 K
To find the final volume, we would use Charles law;
Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Charles' law is given by the formula;
Where;
- V1 and V2 represents the initial and final volumes respectively.
- T1 and T2 represents the initial and final temperatures respectively.
Making V2 as the subject formula, we have;
<em>Final volume, V2 = 13.18 Liters</em>
