Is potassium hydroxide contains potassium oxygen and helium?
NO!!! Potassium hydroxide contains;- 1 X potassium(K) 1 x Oxygen (O) 1 x Hydrogen (H). To give the formula 'KOH'. NB Helium is 'He'. It is the most unreactive element of all. It remains in the monatomic gaseous state. So it is not part of potassium hydroxide.
What is the color of Potassium oxide?
When freshly cut it is silvery in colour but it quickly tarnished as it reacts with oxygen in the air. all alkali metals give characteristic flame colour wich are used to identify them potassium has the colour LILAC
Which does not give oxygen on heating?
Mercury(II) oxide does not give off oxygen when heated; instead, it decomposes into mercury and oxygen gas.
Why do potassium oxide and potassium chloride give off the same colour of light in a flame test?
Potassium ions are responsible for the characteristic violet color observed in flame tests. Both potassium oxide and potassium chloride contain potassium ions that emit the same color of light when heated in a flame due to the same electronic transitions in the potassium atoms.
How do you name the ionic compound for CaO?
CaO would be named Calcium Oxide. When O is present in a chemical formula without an added notation (such as O2) we give it the term Oxide.

What will react with copper to give us copper oxide?
oxygen

Is potassium permanganate an element?
No, it is a compound. Its chemical formula is KMnO4, and from this we can see that it contains the elements potassium, manganese and oxygen. Potassium permangante is a strong oxidising agent and dissolves in water to give deep purple solutions which may stain hands and clothing. Its crystals are purplish black.
How many moles of potassium chlorate are needed to give 1.50 moles of oxygen?
The answer is 1 mole potassium chlorate.
Is magnesium oxide a good conductor?
yes. magnesium oxide is a good conductor . It ionise to give magnesium and oxygen ions.
How do you name the ionic compound for CaO?
CaO would be named Calcium Oxide. When O is present in a chemical formula without an added notation (such as O2) we give it the term Oxide.
What is the correct formula for an ionic compound composed of potassium and hydroxide?
The correct formula for an ionic compound composed of potassium and hydroxide is KOH, where K represents potassium and OH represents hydroxide.
Does mercuric oxide decompose on heating?
Mercuric oxide decomposes upon heating to give off mercury and oxygen.
Why is there only one oxygen ion in magnesium oxide?
Magnesium oxide has a chemical formula of MgO because magnesium (Mg) has a +2 charge and oxygen (O) has a -2 charge. When these ions combine, one magnesium ion and one oxygen ion are needed to balance out the charges and form a stable compound.
