The compound magnesium phosphate has the chemical formula Mg3(PO4)2. In this compound, phosphorous and oxygen act together as on
Lapatulllka [165]

Answer:

The 2 in the formula means that, there are 2 phosphate anions that forms the salt.

Explanation:

Magnesium phosphate is a ionic salt.

The formula indicates that 3 moles of Mg and 2 moles of anion phosphate are contained in 1 mol of compound.

3Mg²⁺ + 2PO₄⁻³  →  Mg₃(PO₄)₂

The phosphate anion comes from phosphoric acid and it is generated when the acid loses the 3 protons.

H₃PO₄  →  3H⁺  + PO₄⁻³

Phosphate has a negative charge of -3, so when it bond to magnesium, which has a charge of +2, there must be 3 magnesium and 2 phosphate to make a global charge +6 -6 in the ions

What are the standard temperature and pressure conditions enthalpy is usually measured under?
oksian1 [2.3K]

The standard temperature and pressure conditions enthalpy is usually measured under are 1kPa and 273K (option A).

<h3>What is enthalpy?</h3>

Enthalpy in thermodynamics is a measure of the heat content of a chemical or physical system.

Enthalpy is the sum of the internal energy and pressure times volume It can be calculated using the following formula:

H = E + P V

Where;

H = Enthalpy

E = internal energy

P = pressure

V = volume

However, the enthalpy of a substance is usually measured under standard temperature and pressure.

  • The standard temperature is 273 Kelvin or K
  • The standard pressure is 1kPa
