2HgO------->2Hg+O2
The balanced chemical equation for the reaction between mercury(II) nitrate and sodium sulfide is: Hg(NO3)2 + Na2S -> HgS + 2NaNO3
The chemical formula for mercury(II) oxide is HgO. It is composed of one mercury (Hg) atom and one oxygen (O) atom.
3AgNO3(aq) + Na3PO4(aq) --> Ag3PO4(s) + 3NaNO3(aq)
Na2S + Hg(NO3)2 -> 2Na(NO3) + HgS ^ Na is Sodium and its not even in the equation so the balanced equation is: Hg2SO4 + NH4NO3>>>>Hg2NO3+SO4 I'm Assuming you mean mercury(i) sulfate+ ammonium nitrate? if so: Hg2(SO4) + 2[(NH4)(NO3)] ----> 2[Hg(NO3)] + {[(NH4)2] (SO4)} & it's a double replacement reaction (Since most people just come here to get quick answers for homework, I'm not going to bother explaining how to get that.)
This equation is 2 H2O (liquid) = 2 H2 (gas) + O2 (gas)There must be 4 atoms / 2 diatomic molecules of hydrogen on each side to yield O2This is the electrolysis of water.
the balanced equation of mercuryII oxide HgO undergoes a chemical change to form mercury and oxygen is given as .2HgO(s) --> 2Hg(l) + O2(g)The reaction is a redox reaction. Mercury (II) is reduced to zero charge. Oxygen is oxidized to zero charge.Molecule: HgO(s)
its already balanced
The balanced chemical equation for the reaction of mercury (Hg) with hydrochloric acid (HCl) is: Hg + 2HCl -> HgCl2 + H2
The balanced chemical equation for the reaction between mercury(II) nitrate and sodium sulfide is: Hg(NO3)2 + Na2S -> HgS + 2NaNO3
The chemical formula for mercury(II) oxide is HgO. It is composed of one mercury (Hg) atom and one oxygen (O) atom.
3AgNO3(aq) + Na3PO4(aq) --> Ag3PO4(s) + 3NaNO3(aq)
When heated, mercury(I) oxide decomposes to form mercury and oxygen gas. The balanced chemical equation for this reaction is: 2 Hg2O -> 4 Hg + O2
Since mercury can be either a 1+ ion called mercury(I), or a 2+ ion called mercury(II), there are two possibilities.Formulaspotassium chloride is KClpotassium iodide is KImercury(I) chloride is HgClmercury(I) iodide is HgImercury(II) chloride is HgCl2mercury(II) iodide is HgCl2Equation with Mercury(I)KCl + HgI --> HgCl + KIEquation with Mercury(II)2KCl + HgI2 --> HgCl2 + 2KI
A balanced equation has equal numbers of each type of atom on each side of the equation.Balanced chemical equations mercury sulfide plus ammonium nitrate is as follows :Hg2(SO4) + 2[(NH4)(NO3)] ----> 2[Hg(NO3)] + {[(NH4)2] (SO4)}
The word equation for heated mercury is "mercury reacts with oxygen to form mercury oxide."
When heated, mercury(II) oxide decomposes into mercury and oxygen gas. This is a chemical reaction where mercury(II) oxide undergoes thermal decomposition. The balanced chemical equation for this reaction is: 2HgO(s) → 2Hg(l) + O2(g)
Potassium is in group one, so according to solubility rules, it will aways be soluble and therefore a spectator ion. That means that it will not take part in the chemical reaction and in a net equation it would not have to be included. HgCl2 + K2S yields HgS + 2KCl(aquious)
