What is the formula of the sulphate of a metal whose valency in 3?
The formula for the sulfate of a metal with a valency of 3 would be M2(SO4)3, where M represents the metal. This formula is derived from the charges on the sulfate ion (SO4) which is 2-, requiring three of them to balance the 3+ charge of the metal.
What is the chemical formula for metal?
There is no chemical formula for a metal. Metals are elements, whose chemical symbols are on the periodic table of the elements.
What is the hydroxide ion concentration of a solution whose pH is 12.40?
The hydroxide ion concentration can be calculated using the formula [OH-] = 10^-(14-pH). Thus, for a solution with pH 12.40, the hydroxide ion concentration would be 10^-(14-12.40), which is equal to 2.51 x 10^-2 M.
What is the concentration of the hydroxide ions of a solution whose pH is 4.0?
The concentration of hydroxide ions (OH-) in a solution with a pH of 4.0 is 1 x 10^-10 mol/L. This value can be calculated using the relationship between pH and pOH (pOH = 14 - pH), and then using the formula for the concentration of hydroxide ions in water at a given pOH.
What is the valency of barium?
As Barium's atomic number is 56 and as it has 2 electrons in its outer shell (this is also due to the fact that it is in Group 2) its valency is 2. It loses 2 electrons to attain the electronic configuration of Xenon whose atomic number is 54, so it is electropositive and is a metal.Therefore its valency is 2+.

Is lime water the same as hydrochloric acid?
No -limewater is a base, specfically a solution of calcium hydroxide or Ca(OH)2 Hydrochloric acid is a solution of hydrogen chloride or HCl
Why do the nonmetals in group 18 rarely react with other elements to form compounds?
They are the noble gases whose outermost (valency) orbitals are full.
What is the molecular formula of a compound whose empirical formula is CH3 and whose molar mass is 30 g?
C2h6
Radical - positive and negative radical in chemistry?
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
Which metal which food is made?
iron is the metal whose food is made
What element is a soft valuable metal whose purity is measured in carats?
Gold is a soft valuable metal whose purity is measured in carats.
What is the oh- of a soultion whose pH is 10?
The concentration of hydroxide ions (OH-) can be calculated from the pH using the formula: [OH-] = 10^(14 - pH). In this case, for a solution with a pH of 10, the concentration of OH- ions would be 10^(-4) M.
