What is the name of the compound formula K2O?
Potassium oxide is a ionic lattice which is made out of potassium ions and oxide ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is K2O which is used also as the chemical formula for the compound.
What mass of potasium oxide is formed when 7.8g of potasium is burned in oxygen?
4.4g
Which salt is produced when copper oxide reacts with hydrochloric acid?
Copper oxide and hydrochloric acid will produce copper chloride.
What salt is formed form neutralization reaction between perchloric acid and potassium hydroxide?
A hydroxide refers to the OH- polyatomic ion and is formed when an oxygen makes a covalent bond with one hydrogen (however you would not see such ions free in nature as they would more probably be in compounds). Potassium hydroxide (KOH) is formed when Potassium forms ionic bonds with OH- ions while Potassium Oxide (K2O) is formed when potassium forms ionic bonds with the Oxide (O2-) ions. Hydrochloric acid + Potassium Hydroxide ---> Potassium Chloride + Water i.e. HCl(aq) + KOH (aq) ----> KCl (aq) + H2O (l) This reaction is a neutralization reaction and occurs when an acid (HCl) reacts with a base (KOH).
What salt is produced when copper oxide reacts with hydrochloric acid?
Zn + HCl = ZnCl + H the will be hydrogen and it will make a squeaky pop noise
what is the balanced equation for copper(II)oxide and potassium chloride?
The balanced equation for copper(II) oxide and potassium chloride is CuO + 2KCl → CuCl2 + K2O When copper(II) oxide reacts with potassium chloride then it forms copper(II) chloride and potassium oxide.
Is potassium oxide soluble?
Potassium oxide reacts with water to form soluble potassium hydroxide.
What happens when oxygen reacts with potassium?
It forms an oxide
Is potassium oxide an alkaline?
No Potassium oxide is extremely basic (alkaline).
What is the name of the compound formula K2O?
Potassium oxide is a ionic lattice which is made out of potassium ions and oxide ions. Therefore, separate 'molecules of this compound do not exist. The empirical formula itself is K2O which is used also as the chemical formula for the compound.
How does potassium make its oxide and hydroxide?
Potassium makes its oxide by direct reaction with oxygen molecules (although the principal product is potassium superoxide). Potassium reacts with water to form its hydroxide.
Why do potassium oxide and potassium chloride give off the same colour of light in a flame test?
The color is from the potassium !
Potassium oxide covalent or ionic bond?
Potassium chloride is ionic as are all potassium compounds.
Name some chemicals?
sodium chloride,calcium oxide,potassium
Which salt will be made when copper oxide reacts with hydrochloric acid?
copper chloride
What does hydrochloric acid and calcium oxide make?
Calcium + water. Chloride Since it is a neutralisation reaction: Acid + metal oxide = salt + water Hydrogen Calcium Calcium Water Chloride + Oxide = Chloride +
What mass of potasium oxide is formed when 7.8g of potasium is burned in oxygen?
4.4g
