It has no chemical name but it has chemical structure!
Elements in the same column of the periodic table exhibit similar properties (periodicity). Carbon, in Group XIV (14), and elements below it in the same column react in similar fashion. The most similar element to carbon is silicon (Si).
c. decreased with increasing viscosity of the fluid being filtered.
Filtration is a method of separation which is useful in separating solids from the fluids (either liquids or gases) by adding a specific medium through which only fluid can pass. Fluid which passes through the filter is known as the filtrate.
Increasing the viscosity of the fluid which is being filtered decreases the rate of filtration as the liquid being more viscous take more time to cross the pores of the filter. Thus, rate of filtration is indirectly proportional to the viscosity of the fluid which is being filtered.
So, option C is correct.
An energy level of a certain atom is further divided into the orbitals. There are four (4) orbitals. These are the s orbitals, p orbitals, d orbitals, and f orbitals. They are already arranged above as to how they are to be filled. The number of electrons that each can hold are as follows:
s orbitals = 2 electrons
p orbitals = 6 electrons
d orbitals = 10 electrons
f orbitals = 14 electrons
Explanation: because silicon cannot share over 3 bonds
