Magnesium reacts with a certain element to form a compound with the general formula MgX. What would the most likely formula be f
ziro4ka [17]

Answer:K2X

Explanation: Valency can be defined as the combining power of an element. It is the valency that dictates the value an element will have when writing a chemical formula for its compound.

MgX is a compound of magnesium and an element X. The valency of magnesium in most of its compound is +2. Now for the 2 to have been absent in the chemical formula, this shows that the element X itself have a valency if -2 for the valencies of both to have canceled out.

Now considering the element potassium, it is an alkaline metal belonging to group 1 of the periodic table. Hence, it is expected that it has a valency of +1

Forming a compound with element X means there would be an exchange of valencies between the two. We have established that x has a valency of -2. The formula of the compound thus formed by exchanging the valencies of both element would be K2X

Veronika [31]

Answer: Calculate the molar mass of Mg3(PO4)2 in grams per mole or search for a chemical formula or substance.

Missing: 643.21 ‎ Must include: 643.21. A balloon is filled with 36.2 liters of Cl2 gas at STP. How many moles of chlorine gas are inside? Solution: 36.2

Missing: 4.061 ‎Must include: 4.061 .For H2O, there is one atom of oxygen and two atoms of hydrogen. A molecule can be made of only one type of atom. In its stable molecular form, oxygen exists as two atoms and is written O2. to distinguish it from an atom of oxygen molecule of three oxygen atoms, in grams per mole or search for a chemical ... Did you mean to find the molecular weight of one of these similar formulas- 80.34.
