Answer:
a number which occurs in the theoretical expression for the value of some quantized property of a subatomic particle, atom, or molecule and can only have certain integral or half-integral values.
Explanation:
In other words, it is a number that is Part of scientific theories or chemistry
Answer:
V₂ = 1592.32 L
Explanation:
Given data:
Initial number of moles = 1.54 mol
Initial volume = 383.2 L
Final volume = ?
Final number of moles = 6.4 mol
Solution:
Formula:
V₁/n₁ = V₂/n₂
V₁ = Initial volume
n₁ = initial number of moles
V₂ = Final volume
n₂ = Final number of moles
now we will put the values in formula.
V₁/n₁ = V₂/n₂
383.2 L / 1.54 mol = V₂/ 6.4 mol
V₂ = 248.8 L/mol ×6.4 mol
V₂ = 1592.32 L
Of the following given choices;
A. iron
B. plastic
C. aluminum
D. wood
The answer is; A
Magnetism is the result from the unpaired spins of electrons in the orbital shells of the atoms of an element. Aluminum (though a metal with +3 valency like iron) has it S and P orbitals filled hence most of its electrons are paired. Iron, on the other hand, a transitional metal, has a D orbital that can be filled before the P orbital is filled. Therefore, there is a higher net unpaired spin of electrons giving the atoms net magnetic properties.
They share four electrons, two from each oxygen atom
