Answer:
It's C, direct and peripheral.
Explanation:
Just took the test
Answer: C) Tetrahedral
Explanation:
The number of electron pairs is 4 that means the hybridization will be
but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.
Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be
.
Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be
.
Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be
.
Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be
.
Answer:
isn't it erosion

if i am wrong sorry have a good day
Answer:
Water has the greatest ΔEN
ΔEN H₂O → 3.4 - 2.1 = 1.3 Option D.
Explanation:
We should find the Electronegativity data in the Periodic table for all the elements:
C : 2.6
O: 3.4
H: 2.1
S: 2.6
N: 3.0
a. ΔEN CO₂ → 3.4 - 2.6 = 0.4
b. ΔEN H₂S → 2.6 - 2.1 = 0.5
c. ΔEN NH₃ → 3 - 2.1= 0.9
d. ΔEN H₂O → 3.4 - 2.1 = 1.3
Answer:
5230J
Explanation:
Mass (m) = 250g
Initial temperature (T1) = 25°C
Final temperature (T2) = 30°C
Specific heat capacity (c) = 4.184J/g°C
Heat energy (Q) = ?
Heat energy (Q) = Mc∇T
Q = heat energy
M = mass of the substance
C = specific heat capacity
∇T = change in temperature = T2 - T1
Q = 250 × 4.184 × (30 - 25)
Q = 1046 ×5
Q = 5230J
The heat energy required to raise the temperature of 250g of water from 25°C to 30°C is 5230J
