What is the compound for HgF?
WARNING=Never ever try this at home. This reaction should be done in minute quantities, and outside the home.When the orange poisonous compound Mercury(II) Oxide is heated, it produces poisonous vapours of Mercury (which become liquid after reaching the room temperature) and Oxygen. Here is the balanced equation for this=2 HgO ---Δ---> 2 Hg + O2
When bright red mercury (II) oxide is heated in a test tube oxygen gas is evolved and droplets of liquid mercury condense at the cooler top of the test tube.?
Yes, it is correct.
What is the process in which electricity converts oxygen into ozone?
The ozone created by electricity is still ozone.
Oxygen combined with one other element is an?
Oxygen combined with one other element is an oxide.
How big is a tree before it produces oxygen?
It at least has to be a sprout before it produces oxygen.
What would be the combined mass of the released oxygen and mercury if 20g of mercury oxide were heated?
10
When Mercury oxide is heated it forms?
When Hg2+ (mercury oxide) is heated it creates both Hg (liquid mercury) and O2 (oxygen gas)
What is the word equation for solid mercury two oxide breads down when heated forming the elements mercury and oxygen?
Mercury+Oxygen----> Mercury Oxide
Mercury oxide is heated to form oxygen?
A chemical reaction happens when mercury is heated and reacts with oxygen. This reaction results in the creation of mercuric oxide, an orange or red compound.
What combined wih the magnesium when it was ignited in The Crucible?
oxygen. O2 was combined with magnesium when it ws heated in the crucible
What element when combined with oxygen produces a compound essential to life?
Hydrogen
What happens when Hg oxide is heated?
When mercuric oxide is strongly heated in a hard glass tube, it decomposes, globules of mercury collect in the cooler part of the tube and oxygen gas is evolved. It may be collected over mercury in a pure and dry state.
Why does mercury weigh more when heated with oxygen?
It's because atoms of oxygen join atoms of mercury, forming new chemical -- mercury oxide HgO. Since it consists of two elements, its weight will be bigger.
When potassium chloride and sugar is combined with heat and oxygen and expanding gases it produces an effective rocket what?
fuel

Is sulfur combined with oxygen produces sulfur dioxide a physical change?
This is a chemical change because there is a molecular change in the composition. A physical change results when the size, shape, phase, texture etc. of a substance changes. Liquid water heated to water vapor is a physical change.

Yes, it is correct.
