Answer is c , because it's convection currents
<h3><u>Answer;</u></h3>
B. It involves loss of electrons.
<h3><u>Explanation;</u></h3>
- Oxidation occurs when electrons are lost by an atom while reduction refers to the gain of electrons by an atom.
- <u><em>In this case, magnesium atom reacts with sulfur to form magnesium sulfide by loosing two electrons and forming magnesium ion (Mg2+). Therefore magnesium undergoes oxidation.</em></u>
- Sulfur, on the other hand will gain electrons to form Sulfide ions, therefore it undergoes reduction.
- Therefore;<em><u> In magnesium sulfide (MgS), magnesium loses two electrons and becomes a cation with a positive-two charge. Likewise, sulfur obtains the two electrons lost from magnesium and becomes an anion with a negative-two charge. However, the overall charge of MgS is zero.</u></em>
Answer:
42.2 moles of H3PO4
Explanation:
The equation of the reaction is:
P2O5(s) + 3 H2O(l) ⟶ 2 H3PO4.
First we must obtain the number of moles of P2O5 from
Number of moles of P2O5= reacting mass of P2O5/molar mass of P2O5
Molar mass of P2O5= 141.9445 g/mol
Number of moles= 3000g/141.9445 g/mol = 21.1 moles of P2O5
From the reaction equation;
1 mole of P2O5 yields 2 moles of H3PO4
21.1 moles of P2O5 will yield 21.1 ×2/ 1 = 42.2 moles of H3PO4
