The interaction between the substances and stomata is a chemical reaction, light energy strikes at the chlorophyll molecules, whose electrons gets excited to a state of higher energy, and they come back to their state of lower energy by emission of energy, which is accepted by a chain of acceptors, and energy is generated.
According to valence bond theory, atomic orbitals of slightly different mix and recast to form new orbitals of identical energies and properties. This process as called hybridization and, new generated orbitals are referred as hybridized orbitals.
Also, according to assumption of VBT, only central atom undergoes hybridization.
In case of HNO3, N is a central atom and it undergoes sp2 hybridization in HNO3. The structure of HNO3 is planner.
Further, HNO3 comprises of H+ and NO3- ion. Here, role of H+ is to act as counter ion and balance the charge on NO3-
Now, when HNO3 is mixed in water, it undergoes dissociation to generate H+ and NO3- ion. Here, parent ion i.e. NO3- is not disturbed. Hence, it's hybridization will not change. Only there will be minor variation in bond length and bond angle because of interaction of NO3- with H2O molecules.
Molar mass of nitric acid (HNO3) =atomic mass of hydrogen + atomic mass of nitrogen +3x atomic mass of oxygen . The molar mass of nitric acid (HNO3) is 63.0144 gram per mole, but you have 3.4 moles. Therefore; the answer is 63.0144 g/mole x 3.4 moles = 214.24896 grams.
Answer:
Explanation:
In the figure attached, I have numbered the carbon atoms to permit to count them easily.
<u>1. Carbon atoms</u>
Each vertex without a letter represents a carbon atom:
- Count them: 17 (they are numbered on the figure attached)
<u>2. Hydrogen atoms</u>
For each carbon subract 1 for each bond and subtract 1 for each group attached to it:
- Carbon 1: 4 - 2 = 2
- Carbon 2: 4 - 2 = 2
- Carbon 3: 4 - 2 = 2
- Carbon 4: 4 - 2 = 2
- Carbon 5: 4 - 4 = 0
- Carbon 6: 4 - 4 = 0
- Carbon 7: 4 - 3 = 1
- Carbon 8: 4 - 4 = 0
- Carbon 9: 4 - 4 = 0
- Carbon 10: 4 - 3 = 1
- Carbon 11: 4 - 4 = 0
- Carbon 12: 4 - 4 = 0
- Carbon 13: 4 - 3 = 1
- Carbon 14: 4 - 3 = 1
- Carbon 15: 4 - 2 = 2
- Carbon 16: 4 - 2 = 2
- Carbon 17: 4 - 4 = 0
Total H atoms attached to C atoms:
- 2 + 2 + 2 + 2 + 1 + 1 + 1 + 1 + 2 + 2 = 16
Total H atoms in all: 16 + 2 = 18
