Answer:
Density: The molecules of a liquid are packed relatively close together. Consequently, liquids are much denser than gases. The density of a liquid is typically about the same as the density of the solid state of the substance.
In a gas, the distance between molecules, whether monatomic or polyatomic, is very large compared with the size of the molecules; thus gases have a low density and are highly compressible. In contrast, the molecules in liquids are very close together, with essentially no empty space between them

Silver is Ag from the latin Argentum
Lead is Pb from the latin Plumbum
It is endothermic reaction ΔH>0 (sign is +).
Because it is spontaneous reaction ΔG<span><0 (Gibbs free energy)
</span>ΔG=ΔH-TΔS, so must be TΔS>ΔH and ΔS<span>>0 (sign +).</span>
Answer:
H2SO4 + CO3 = H2CO3 + SO4
Explanation:
H2SO4 + CO3
This is the reaction of sulphuric acid and carbon trioxide.
Balanced reaction is;
H2SO4 + CO3 = H2CO3 + SO4
So they react to produce carbonic acid and sulfate.
16 is the mass of an atom of Oxygen
