Single replacement, one atom takes the place of another. There’s one element and one compound and they switch
element + compound —> (and then either the +ions switch with each other or the -ions)
A+BC—> AC + B
Silicon (si) has two electrons in its outer p orbitals.
Explanation:
For the element of SILICON, you previously know that the atomic number shows the number of electrons. That indicates there are 14 electrons in a silicon atom. Looking at the design, you can see there are two particles in shell one, eight in shell two, and four in shell three. Si which is 4 elements from the left side of the table,first 2 electrons are s orbitals when next two electrons go to Si
The dalton or unified atomic mass unit is a unit of mass widely used in physics and chemistry. It is defined as 1⁄12 of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state and at rest. The atomic mass constant, denoted mᵤ is defined identically, giving mᵤ = m/12 = 1 Da.
Answer:
Kb =
Explanation:
For a weak organic base, the formula to find is given by:
where c is the concentration of base.
Here c=
Substituting the above values in the formula,we get:
Hence:
Kb =
