What is the M in M2O3?
That is the valency of metal is 3. Elements with valency 3 belongs to group IIIA (13) of the periodic table. So,metal M belongs to group IIA and 3rd period of periodic table.Tha t means metal M is Aluminium.
Which element forms an oxide with the formula M2O3?
Since it is a metal its valence shell has 3 electrons.So its electronic configuration is 2 8 3Atomic number =13Hence the metal is Aluminum with valency 3. A metal M forms an oxide having the formula `M_2O_3. ` It belongs to 3rd period in the Modern Periodic table.
Which metal M will form the oxide M2O3?
From the formula M2O3 its valency is 3. Since it is a metal, its valence shell has 3 electrons. Hence the metal is Aluminum with valency 3.
What will be the formula of its phosphate?
M2(PO4)

What is the atomic number of metal M?
The atomic mass of metal M is 56. Calculate the empirical formula of its oxide containing 70\% of M. (i) To calculate the percentage of oxygen.
What is the formula of chloride of metal M?
The formula of the chloride of metal M is MCl2.
What is the formula for phosphate of M?
Phosphate of metal M has the formula M3(PO4)2.
What is the formula for oxide M?
Answer Expert Verified. The Chemical formula of oxide is MO, It means, M has Valency 2 because Oxygen has its Valency 2. So, both the 2 cuts M₂O₂ = MO.
What is the chemical name of fe3o4?
Iron Oxide
Iron Oxide (fe3o4)
What is the empirical formula of an oxide of element containing 40\% element by mass?
So, Empirical Formula is EO3.
What is the valency of a metal with formula M2O3?
Expert Answer: A metal M forms an oxide having the formula M2O3. That is the valency of metal is 3. Elements with valency 3 belongs to group IIIA (13) of the periodic table.
What is the molecular mass of the oxide of the metal?
The oxide of an element possess the molecular formula M2O3. If the equivqlent mass of the metal is 9,the molecular mass of the oxide will be?? The molecular mass of the oxide will be 102. In this, if the options weren’t there, couldn’t it have been YX 2 (2 in subscript)
What is the formula for 60g of oxygen that reacts with metal?
60 gm oxygen reacts with = 40 gm of Metal. Now we know that the Atomic Weight of the Metal is =32. So weight of oxygen that reacts with 32 gm of the metal in the oxide’B’ is = 32×60/40=48. So the OXIDE ‘B’ has 1 atom of metal to ‘3′ atoms of oxygen. So the formula 60 gm oxygen reacts with = 40 gm of Metal.
What is the ionic formula for sisiunce oxygen?
Siunce oxygen is divalent, the presence of 3 oxygen atoms in M₂O₃ means that the M atoms must present electrons. Since this is done with only 2 M atoms, they must be trivalent. The phosphate ion, (PO₄)³⁻, is trivalent too, so M³⁺ and (PO₄)³⁻ will combine in a 1:1 ratio.
