Answer:
3 Mg, 2 P, 14 O, 12 H
Explanation:
Without mincing words, let us dive straight into the solution for the problem above. This question is all about how how equations showing chemical reactions are being balanced.
From the question, we are giving the reactants: which are Mg(OH)2 and H3PO4 and in order to balance the reaction, the number of atoms in the reactants must be equal to the number of atoms in the products side of the reaction. Since, we have 3 Magnesium atoms, 2 Phosphorus atoms, 14 Oxygen atoms, and 12 Hydrogen atoms in the reactants side of the equation, the same number of atoms is expected in the products side.

La 'H' en el pH se refiere a la concentración de iones de hidrógeno en una solución. El símbolo químico del hidrógeno es H y siempre está en mayúscula. La 'p' es solo un símbolo matemático que significa 'logaritmo negativo'.
The equation MgO + 2HCl → MgCl₂ + H₂O is a balanced equation.
- A balanced chemical equation contains equal number of atoms on both sides of the equation.
- The equation is MgO + 2HCl → MgCl₂ + H₂O which contains 1 atom of Mg, 2 atoms of chlorine, 2 atoms of chlorine, 1 atom of oxygen on both reactants and products sides.
- So the equation is balanced.
- An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction.
- In other words, both sides of the reaction have equal amounts of mass and charge.
- It follows law of conservation of mass.
- Mass is neither created nor destroyed rather it can be transferred from one form to another.

To get the density of the material, the formula would be: mass divided by volume which is denoted by d = m/v
So for this problem, the mass is 241.25 g and the volume is 12.5 cm^3
so plugging in the data, we have: d = 241.25 g / 12.5 cm^3 = 19.3 g/cm^3
The answer is Tungsten, you could see it in the table, in the attached file.
