What is the balanced equation for HgO?
What is the balanced equation for HgO?
Search by reactants (HgO) and by products (Hg, O 2)
| 1 | HgO → O2 + Hg |
|---|---|
| 2 | H2O2 + HgO → H2O + O2 + Hg |
What is the formula for decomposition?
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
When a 14.2 g sample of mercury II oxide HgO is decomposed into its elements by heating 13.2 g Hg is obtained what is the percent composition of the compound?
Explanation: Mercuric oxide decomposes to the elements mercury and oxygen. Dividing the weight of the mercury (13.2 g) by the weight of the oxide before heating (14.2 g), and using three significant digits to match the weight measurements, we get 0.930 = 93.0% for the proportion of mercury. The remainder is oxygen.

Is N2O3 ionic or molecular?
Answer and Explanation: Dinitrogen trioxide (N2O3) is a covalent molecule because it has two nonmetals.
Is sno2 an ionic compound?
Tin, Sn, is a metal and oxygen, O, is a non-metal. So, ionic. There is a rule that says that if the electronegativity difference between the two atoms in a bond is greater than 2 then it is ionic. so, NOT ionic, just polar covalent.
Is MgO molecular or ionic?
valence electrons …the ionic compound MgO (magnesium oxide).
What is the chemical formula of MgO?
Magnesium oxide
How does magnesium react with oxygen?
When magnesium reacts with oxygen, it produces light bright enough to blind you temporarily. Magnesium burns so bright because the reaction releases a lot of heat. As a result of this exothermic reaction, magnesium gives two electrons to oxygen, forming powdery magnesium oxide (MgO).
What is the formula for Na and S?
Na2S
What occurs in an ionic bond?
Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion). A brief treatment of ionic bonds follows.
What is the symbol of sodium sulphide?
