K Ca Fe Zn. Which element can form more than one binary compound with chlorine. A oxide has the formula of XO3.

100 1 rating Transcribed image text. Upon strong heating the oxide undergoes decomposition according to the following equation. Valency is 1 HO2 or.

1 Group 1 2 Group 2 3 Group 13 4 Group 17. 2006 Q41 Metal X forms an oxide with the formula X 2 O. X0 - x 2.

B Element X belongs to Group 2 since it has two valence electrons. A metal X from third period which forms an oxide with formula XO is Magnesium. The chemical formula of oxide of an element X is X2O5.

If the second oxide contains 60 of oxygen the formula of the second oxide is. If the formula of an oxide of element X is XO what is the formula of the chloride of X. 2 IIA When a fluorine atom becomes an ion it will.

XCl2 - This is the best answer becaus. Magnesium belongs to alkali earth metal group. JAMB NECO WAEC NABTEB IJMB Question.

2X 2 Os 4Xs O 2 g Complete decomposition of 290 g of the oxide gives 150 cm 3 of oxygen measured at room temperature and pressure. The oxide of metal X has the formula XO. That oxide reacts with H2 g to form the free metal and liquid water.

Atomic number 12. A The element X is electrically conductive. A oxide has the formula of XO3.

The oxide of metal X has the formula XO. Which group in the periodic table contains metal X. 100 g of the oxide of metal X atomic mass 64 gave 080 g of the metal when reduced with hydrogen.

Electronic configuration Ne 3s2. It is the ninth most abundant element in the universe. If the second oxide contains.

Metal X forms two oxides. It is the fourth most commonly available element in the earth after Iron oxygen and silicon. In the case of compound XO both the elements are divalent since the valency of oxygen is 2.

C The formula of the compound formed when X reacts with chlorine is X C l 2. What is the relative atomic mass of X. Gain an electron and decrease in size B.

Which group in the Periodic Table contains metal X. X is Sulphur From the choices Aluminium is clearly rejected since it is a metal Carbon CO2 exist but something like CO3 does not exist the valency of C is 4 so CO3 2- anion do exist but it is not an oxideThis option is also rejected. Formula of the first oxide is.

The compound overall needs to be neutral so you add up all the charges from the oxygen and add whatever you need to make it neutral. An element X forms two oxides. Gain an electron and increase in size.

When a fluorine atom becomes an ion it will A. Which group in the Periodic Table contains metal X. Since the valency of the element X is 2 and it is showing electrical conductivity therefore it is a metal.

Therefore the valency of X should also be 2. B We can conclude that X belongs to Group 2. Gain an electron and increase in size.

Write the chemical formula of its chloride. If X represents an element of Group 1 1A the formula of its oxide would be a X₂O b X₂O₃ c XO d XO₂. Answer 1 of 3.

It contains 50 of oxygen. The oxide of metal X has the formula XO. Therefore it is a metal.

A Since element X combines with oxygen to form an oxide XO so its valence electrons is 2. FeO - oxidation state of iron 2 since oxygen.
