1) write the equation and balance the equation
2) convert the volume of the gas to moles of the gas PV=nRT
3) according to the stoichiometry of the reaction one mol of gas is produced by one mol of salt. Convert the mol of gas to mol of salt
4) calculate the molar mass of the salt and convert the mol of salt to g of salt (m= nxMM)</span>
It indicates that the river water is very good quality with nutrients and minerals to support an ecosystem.
Answer:
Molar solubility is 1.12x10⁻⁴M
Explanation:
The dissolution of magnesium hydroxide is:
Mg(OH)₂(s) ⇄ Mg²⁺ + 2OH⁻
The molar solubility represents the moles of the solid that the solution can dissolve, that could be written as:
Mg(OH)₂(s) ⇄ X + 2X
<em>Where X is solubility.</em>
<em />
If you obtained a [OH⁻] = 2.24x10⁻⁴M and you know [OH⁻] = 2X:
2X = 2.24x10⁻⁴M
X = 2.24x10⁻⁴M/2
X =1.12x10⁻⁴M
<h3>Molar solubility is 1.12x10⁻⁴M</h3>
Answer:
Filtration, the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles. Either the clarified fluid or the solid particles removed from the fluid may be the desired product.
Crystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of crystal lattice is called a unit cell, which can accept atoms or molecules to grow a macroscopic
crystal.
BRAINLIEST PLEASE, I NEED IT
Mg3(PO4)2 - Mg²⁺ forms base
PO4³⁻ forms acid
Ma(OH)2 is a base(Y).
H3PO4 is an acid(X).
3Mg(OH)2 + 2H3PO4 ---> Mg3(PO4)2 + 3H2O
