Answer:
Hybridization
Explanation:
The variations in bond angles of molecules and ions can be explained by two main concepts.
This is by the valence shell electron pair repulsion theory and hybridization.
- We can arrive at the same shape using both of the mechanism.
- In hybridization, we use hybrid orbitals to predict the shapes of the resulting molecules.
- Hybridization is the mixing or blending of two or more pure atomic orbital to form two or more hybrid atomic orbitals that are identical in shape and energy.
D) melting ice because u can freeze the “ice” back into that state of matter this is called a physical change. HOPE THIS HELPED
Answer:
4.43 Liters
Explanation:
100 g of carbon dioxide = 54.47 liters of carbon dioxide
54.47 / 100 = 0.5447
8 x 0.5447 = 4.43L
Answer:
5 protons, 5 electrons, and 6 neutrons
Answer:
155 kJ
Explanation:
The energy change will be the energy of the reactants less the energy of the products. And the energy of each compound is the sum of the energy of their bonds. Let's call y the N-Br strength.
3HOBR = 3x(459 + 201) = 1980 kJ
NH₃ = 3x386 = 1158 kJ
3H₂O = 3x(2x459) = 2754 kJ
NBr₃ = 3y
3y + 2754 - 1158 - 1980 = 81
3y -384 = 81
3y = 465
y = 155 kJ
