Answer:
Mg₃(PO₄)₂
Explanation:
This is a neutralization reaction between an acid and a base
The acid here is H₃PO₄
base is Mg(OH)₂
Every chemical reaction is made up of reactants on the left side and products formed on the right hand side of the expression;
3Mg(OH)₂
+ 2H₃PO₄
→ Mg₃(PO₄)₂ + 6H₂O
The reaction above is a double replacement reaction in which two ionic compounds gives an insoluble precipitate as a product when their ions displace one another in solution.
The solid formed is Mg₃(PO₄)₂
A mole of any gas occupies 22.4L at standard temperature and pressure (0oC and 1atm). The figure below illustrates how molar volume can be seen when comparing different gases. Samples of helium (He), nitrogen (N2), and methane (CH4) are at STP
The statement for the said principle is "If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium moves to counteract the change." If the reaction gives off energy or is exothermic then the statement will be false however when the reaction absorbs energy or is endothermic then the statement will be true.
Rotting vegetables is a chemical change I think.
