A diatomic molecule (or a non-polar covalent molecule).
<span>[Ne] 3s23p2
In noble gas notation the simplification in the electron distribution to the orbitals is represented where in of all of the lower filled orbitals up to the closest noble gas is enclosed by its symbols in brackets. The remaining orbitals are written in the usual way.The electronic configuration of Si is 1s22s22p63s23p2.The electronic configuration of Ne is 1s22s22p6. Thus the Noble gas notation of silicon (Si) can be written as [Ne] 3s23p2.</span>
Answer:
Filtration and evaporation
Explanation:
A mixture of sand, pink sugar and water can be separated by filtration and evaporation.
The pink sugar is already dissolved in the water but the sand remains undissolved in the water hence it can be filtered off. The filtrate now contains the sugar.
The sugar is obtained from the filtrate by evaporation of the solution to yield the solid pink sugar and steam which can be condensed again to give liquid water.
Ba2Cl
NaS2
The numbers are in subscript
Sulfuric acid or H2SO4 is a strong acid and when in aqueous solution it dissociates completely into hydronium ions or H+ and to HSO4- ions. The sulfuric acid can donate H+ decreasing the pH of a solution. Hope this answers the question.
