Answer:
It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom, 1.992646547 × 10−23 gram, which is assigned an atomic mass of 12 units. ... In this scale 1 atomic mass unit (amu) corresponds to 1.660539040 × 10−24 gram.
Answer:
Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure
Explanation:
The configuration of these elements is as follows;
Cl₁₇ = 2, 8,7 (the outer electron is 7)
Ca₂₀ = 2,8,8,2 (the outer electron is 2)
Ne₁₀ = 2,8 (the outer electron is 8)
Na₁₁ = 2,8,1 (the outer electron is 1)
Based on the outer electron value above, Neon (Ne) has the most stable outer electron configuration because the outer electron is completely filled and it has octet structure.
A for sure sparrows are like birds but sparrows build holes in trees and birds do nests in trees so for sure is a
The visual criterion which has to be assessed is to ensure it's not oily or sticky.
<h3>What is Distillation?</h3>
This is a separation technique that involves the use selective boiling and condensation to separate a liquid mixture into different components.
In the case of Crude reaction product , it is best to ensure that it is not oily or sticky before semimicro distillation is done.
