Answer:
Alkane
Explanation:
Definition of Alkane "any of the series of saturated hydrocarbons including methane, ethane, propane, and higher members. (google dictionary)"
CH4 is methane.
The Orbital configuration for Manganese is as follows:
1s2 2s2 2p6 3s2 3p6 4s2 3d5
It says 3d is shown with five orbitals- this is correct
Then it says the first two orbitals have two electrons-this is incorrect.
When filling in the orbitals for any element, you first need to distribute to ALL orbitals then extras go from there.
The orbital d can have up to 10 electrons so you need to distribute at least one electron to all ten. Since you only have 5 then only 5 orbitals would have electrons in them. In order for ANY of the orbitals to have two electrons, there would need to be AT LEAST 11 electrons to distribute.
The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:
Volume of layer formed=
...... (1)
Volume of layer is also equal to sum of volume of gasoline and water.
Density of gasoline is 
and mass is 34 g thus, volume of gasoline will be:
Now, density of water is 
and mass is 34 g thus, volume of water will be:
Adding both the volumes, volume of layer will be:
Putting the values in equation (1) to solve for height of the layer,
Thus, height of layer is 10.25 cm
