Explanation:
Oxygen has an atomic number of 8 with 2 electrons in its innermost shell (s orbital) and 6 remaining electrons in its outermost shell.
The electronic configuration of the oxygen element will therefore be expressed as;
1s²2s²2p⁴
Since we are to find the valence electron configuration of oxygen, this means we are going to consider only electrons in the outermost shell. The outermost shell of oxygen only contains 6electrons. The electronic configuration will be;
2s²2p⁴ (ignoring the innermost electrons)
Comparing with As^B2p^C
we will have;
As^B = 2s²
A = 2, B = 2
2p^C = 2p⁴
p^c = p⁴
C = 4
Hence A = 2, B = 2 and C = 4
The oxygen ion is represented as O₂²⁻. Therefore the charge of an oxygen ion is -2
To find a solution to this problem it is necessary to apply the concepts related to the Reynolds number and its definitions on the type of fluid.
A Reynolds number less than 2000 considers the laminar fluid, while a Reynolds number greater than 4000 is considered a turbulent fluid. (The intermediate between the two values would be a transient fluid)
The mathematical equation that defines the Reynolds number is given by
Where
Density
V= Velocity
D= Diameter
Viscosity
Our values are given as
The velocity can be find through the Discharge equation,
Q = VA
Where
V = Velocity
A = Area
Replacing,
Replacing at the Reynolds equation,
Since Reynolds' number is greater than 4000, then we consider this a turbulent fluid.
Answer:
C
Explanation:
The weight will always be different while mass is described as the stuff inside an object, and that stays the same.
Such as it weighs differently in space.
Yes, ratio can be expressed in percentage.
When air is blown across the top of an open <span>water bottle, air molecules in the bottle vibrate at a particular frequency and sound is produced in a process called "refraction".
