Question

H3PO4+....-Mg3(PO4)2+...​

Answer 1

Ответ:

$2H_{3}PO_{4}+3Mg=Mg_{3}(PO_{4})_{2}+3H_{2}.$

Объяснение:

При взаимодействии фосфорной кислоты и магния,образуется соль-фосфат магния и водород.

Answer 2

The given chemical equation is:

H3PO4 + Mg3(PO4)2 →

It seems that the equation is incomplete as it doesn't include the products or any reaction conditions. Without more information, it's difficult to provide a complete balanced chemical equation or determine the specific reaction that might occur.

However, based on the reactants provided, it appears to be a double displacement reaction, also known as a precipitation reaction. In such reactions, the positive ions in one compound switch places with the positive ions in the other compound to form new compounds.

In this case, H3PO4 is phosphoric acid, and Mg3(PO4)2 is magnesium phosphate. The balanced equation for the reaction between phosphoric acid and magnesium phosphate would typically involve the exchange of positive ions:

2 H3PO4 + 3 Mg3(PO4)2 → 6 HPO4 + Mg6(PO4)3

Please note that the above balanced equation is an example and may not represent the actual reaction or products without further information.
