There are six molecules in 2H3PO4. Each molecule of phosphoric acid (H3PO4) contains three hydrogen atoms, one phosphorus atom, and four oxygen atoms. Multiplying by two gives a total of six molecules in 2H3PO4.
2H3PO4 refers to two molecules of phosphoric acid. Each molecule of phosphoric acid (H3PO4) contains one phosphorus atom, three oxygen atoms, and four hydrogen atoms.
When calcium reacts with phosphoric acid, calcium phosphate and hydrogen gas are produced. The balanced chemical equation for this reaction is: 3Ca + 2H3PO4 -> Ca3(PO4)2 + 3H2
The balanced equation for the reaction is: 3Ca(OH)2 + 2H3PO4 → Ca3(PO4)2 + 6H2O
3CaCO3 + 2H3PO4 --> Ca3(PO4)2 + 3CO2 + 3H2O It just looks hard but once you get going it's not all that difficult.
3Mg(s) + 2H3PO4(aq) ---> 3H2(g) + Mg3(PO4)2(s)I believe the equation is: Mg + H3PO4 ---> H2 + Mg3PO4. It should be Mg3(PO4)2 because magnesium has a charge of +2 (Mg+2), and phosphate has a charge of -3 (PO4-3), which would become Mg3(PO4)2. Balanced, the equation is 3Mg + 2H3PO4 ---> 3H2 + Mg3(PO4)2

2 molecules=molecules 2 molecules= 2 molecules yayyy!!! We know stuff
There are (5.41 \times 10^{23}) molecules of (O_2) in 0.900 moles.
1 x 1024 molecules
3Mg(s) + 2H3PO4(aq) ---> 3H2(g) + Mg3(PO4)2(s)I believe the equation is: Mg + H3PO4 ---> H2 + Mg3PO4. It should be Mg3(PO4)2 because magnesium has a charge of +2 (Mg+2), and phosphate has a charge of -3 (PO4-3), which would become Mg3(PO4)2. Balanced, the equation is 3Mg + 2H3PO4 ---> 3H2 + Mg3(PO4)2
The balanced equation for the reaction is P4O10 + 6H2O -> 4H3PO4.
no but has many small molecules
A cup of coffee (200 cm3) contains about 1.5 * 1025 molecules.
