A dependent variable is something that whose value depends on another.
a independent variable is something <span> manipulated to determine the value of a dependent </span>variable<span>
a constant is something you do not change</span>
A mixture that results when substances dissolve to form a homogeneous mixture is a solution.
Balanced chemical reaction:
2NaCl(aq) + Hg₂(C₂H₃O₂)₂(aq) → Hg₂Cl₂(s) + 2NaC₂H₃O₂<span>(aq).
</span>NaCl - sodium chloride.
Hg₂(C₂H₃O₂)₂ - mercury(I) acetate.
NaC₂H₃O₂ - sodium acetate.
Hg₂Cl₂ - mercury(I) chloride or <span>mercurous chloride</span>, low solubility in water.
Oxidation number of sodium is +1 and for mercury is also +1.
The atoms on the outermost level are called electrons.
