Upper M g (s) plus 2 upper H right arrow upper M g (a q) plus upper H subscript 2 (g).
Mg + 2H⁺ → Mg²⁺ + H₂
Explanation:
The net ionic equation is the sum of the oxidation half reactions.
The half-reactions are:
Mg → Mg²⁺ + 2e⁻ Oxidation half reaction
2H⁺ + 2e⁻ → H₂ reduction half reaction
Combining the reactions gives:
Mg + 2H⁺ + 2e⁻ → H₂ + Mg²⁺ + 2e⁻
Since the electrons are balanced, they cancel out of the equation,
This leaves behind;
Mg + 2H⁺ → Mg²⁺ + H₂

Answer:
pH reducing agent for acidic soils
Explanation:
Gypsum is not used to reduce soil pH because it will displace the soil H+ but there's no means of extracting the H from the soil. So the pH of the soil remains the same.
Explanation:
The balanced chemical equation of the reaction is:
From the balanced chemical equation,
1 mole of propane forms ------ 3 mol. of 
gas.
The molar mass of propane is 44.1 g/mol.
One mole of any gas at STP occupies --- 22.4 L.
Hence, 44 g of propane forms (3x22.4 L=) 67.2 L of CO2 gas at STP.
Answer:
Thus, 67.2 L of CO2 is formed at STP.
Answer:
The answer is North
Explanation:
The direction of the field is taken to be the direction of the force it would exert on a positive test charge.
