Answer:
.
Explanation:
Magnesium chloride and silver nitrate reacts at a 
ratio:
.
In reality, the nitrate ion from silver nitrate did not take part in this reaction at all. Consider the ionic equation for this very reaction:
.
The precipitate silver chloride 
is insoluble in water and barely ionizes. Hence, 
isn't rewritten as ions.
Net ionic equation:
.
Calculate the initial quantity of nitrate ions in the mixture.
.
Since nitrate ions 
do not take part in any reaction in this mixture, the quantity of this ion would stay the same.
.
However, the volume of the new solution is twice that of the original nitrate solution. Hence, the concentration of nitrate ions in the new solution would be 
of the concentration in the original solution.
.
Answer:
polar
Explanation:
because carbon and sulfur have different electronegativities, the S=C bond is polar.
The entire molecule is nonpolar however because the dipoles (polar bonds) cancel out due to the geometry of the molecule (linear)
Particles of gas are more scarcely placed as compared to that of liquid.
the intermolecular forces will be less in gaseous state and hence is less stable
Answer:
Aluminum had more value than gold in the 1820s, because it was harder to obtain. Hope this helped :)
Mg gained mass because it went from being a single element (on the reactant side) to being a molecule (on the product side).
