Answer:
sp2
Explanation:
Orbital hybridization is defined as the changes in the orbitals of atoms when they pair with electrons of other atoms to form chemical bonds.
C atoms in C2Cl4 or tetrachloroethene have a total of three bond pairs, two with each chlorine atom and one with other carbon atom and zero lone pairs. Thus, C atoms in C2Cl4 is sp2 hybridized.
Hence, the correct answer is "sp2".
C.silicon and oxygen is the answer
The mantle is mostly rich in iron and magnesium oxides and silicates. The mantle is usually divided into the Upper and Lower mantle separated by a transition zone that is smaller than the one that exists between the Inner and Outer core.
Some key things to remember when discussing states of Earth's structure are:
1. Temperatures are highest at depth and increase as you go towards the surface
2. Materials are thicker at depth, with high viscosity, due to increased pressure
Therefore, rocks in the lower mantle are at a high enough temperature that they become soft and are able to flow slowly.
Answer:
1.68L
Explanation:
Step 1:
Data obtained from the question. This includes the following:
Initial Molarity (Mi) = 7M
Initial volume (Vi) 0.6L
Final Molarity (Mf) = 2.5M
Final Volume (Vf) =.?
Step 2:
Determination of the final volume of the solution.
This can be achieved as shown below:
MiVi = MfVf
Divide both side by Mf
Vf = MiVi /Mf
Vf = 7 x 0.6 / 2.5
Vf = 1.68L
Therefore, the new volume of the solution is 1.68L
