Answer:
a) The formal charge on N is 0 in both species.
Explanation:
The formal charge is calculated using the formular;
FC = V-N-B/2
Where;
V = Number of Valence electrons
N = number of nonbonding valence electrons
B = total number of electrons shared in bonds
In NO2-;
The formal charge of N is given as;
FC = 5 - 2 - 6/2
FC = 0
In HNO2
The formal charge of N is given as;
FC = 0
The correct option is;
a) The formal charge on N is 0 in both species.
Sorry but I only know a few
17- decomposers
18- decomposition
21- 10% is lost so 90%
Answer:
Final volume=V₂ = 216.3 mL
Explanation:
Given data:
Initial volume = 120.0 mL
Initial temperature = -12.3 °C (-12.3 +273 = 260.7 K)
Final volume = ?
Final temperature = 197.0 °C (197+273 = 470 K)
Solution:
We will apply Charles Law to solve the problem.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 120 mL × 470 K /260.7K
V₂ = 56400 mL.K /260.7K
V₂ = 216.3 mL
Interaction occurs when light goes into an object as heat energy is Absorbed light.
Absorbed light makes an object dark. Absorption of light is when the light is absorbed by the object and converts it into heat energy. The objects converts the wavelength of light into the larger wavelength of heat. this makes the object warmer and produced energy. Absorption depends on the frequency of light that is transmitted. The wavelength of light defined as the distance between the the two successive troughs of the the light wave.
Therefore, Interaction occurs when light goes into an object as heat energy is Absorbed light.
