All of the above answers are true right answer is option D
because, no bond no molecule no interaction no life,
no bond= only element will exist
Energy would not exist coz energy consumption and excretion takes place during bond formation and bond breaking process!
Answer:
4. Principal and Azimuthal (subsidiary) quantum number
5.Principal, Azimuthal (subsidiary), and magnetic quantum number
6. 10 electrons
7. 32 electrons
8. 36 electrons
Explanation:
4. Principal and Azimuthal (subsidiary) quantum number because in 4d, 4 represent principal quantum number and d- represents azimuthal quantum number (having l- value as 3)
5.Principal, Azimuthal (subsidiary), and magnetic quantum number are the first three because 2 stands for principal, s-for azimuthal (l=0) and magnetic quantum number for s- orbital= 0
6. 10 electrons, because for sublevel with l= 3, is a d-sub-level, and d- can take 10-electrons
7. 32 electrons, using the relationship 2×n^2 for the maximum number of electrons in a shell,
,n= 4 , hence 2×4^2= 32
8. 36 electrons, because n=4 and n= 3 can have the maximum configuration of [Ar]4s^2 3d^10 4p^6
This will sum up to 36- electrons, since Argon has 18 -electrons.
18+2+10+6=36 electrons
Atomic or hybrid orbital on the central br atom makes up the sigma bond between this br and an outer f atom in bromine trifluoride, brf3 is sp2 hybridization
Trigonal hybridization is another name for sp2 hybridization. It entails combining one's' orbital with two 'p' orbitals of equal energy to create a new hybrid orbital known as sp2. A trigonal symmetry combination of s and p orbitals that is kept at 120
One of the hybrid orbitals formed when one s orbital and two p orbitals are mathematically merged to form three new equivalent orbitals orientated toward the corners of a triangle is sp2 hybridization.
The only feasible molecule geometry for sp2 hybridized center atoms is trigonal planar. When all of the bonds are in place, the shape is trigonal planar as well.

Answer: Cycling of carbon in the
ocean is also expected As water moves through and across soils, it carries
valuable nutrients.
Answer:
The energy that is required for the process is:
6230.7 J + 42957 J + 9715.2 J = <u>58902.9 joules</u>
Explanation:
This is a calorimetry problem:
Q = m . C . ΔT
Q = heat; m = mas; C is the specific heat and
ΔT = Final T° - Initial T°
Q = C lat . m
Q = Heat
m = mass
C lar = Latent heat of fusion
First of all we calculate the heat for ice, before it takes the melting point. (from -23°C to 0°C)
Q = 129 g . 2.10 J/g°C . (0°C - (-23°C)
Q = 129 g . 2.10 J/g°C . 23°C → 6230.7 joules
Then, the ice has melted. To be melted and change the state it required:
Q = C lat . m
Q = 333 J/°C . 129 g → 42957 joules
And in the end, we have water that changed its T° from O°C to 18°C
Q = 129 g . 4.184 J/g °C . (18°C - 0°C)
Q = 9715.2 Joules
The energy that is required for the process is:
6230.7 J + 42957 J + 9715.2 J = 58902.9 joules
