2Ag⁺(aq) + Mg(s)→ 2Ag(s) + Mg²⁺ (aq)
<h3>Further explanation</h3>
Given
Standard cell notation:
Mg(s) | Mg2+ (aq) || Ag+(aq)| Ag(s)
Required
a balanced redox reaction
Solution
At the cathode the reduction reaction occurs, the anode oxidation reaction occurs
In reaction:
Ag⁺ + Mg → Ag + Mg²⁺
half-reactions
- at the cathode (reduction reaction)
Ag⁺ (aq) + e⁻ ---> Ag (s) x2
2Ag⁺ (aq) + 2e⁻ ---> 2Ag (s)
- at the anode (oxidation reaction)
Mg (s) → Mg²⁺ (aq) + 2e−
a balanced cell reaction
<em>2Ag⁺(aq) + Mg(s)→ 2Ag(s) + Mg²⁺ (aq)
</em>

Answer:</h3>
4551.37 Pascals
<h3>
Explanation:</h3>
The pressure refers to the force exerted by a substance per unit area.
The pressure is liquid is calculated by;
P = height × density × gravitational acceleration
In this case;
Height = 636.2 mm
Density = 0.7300 g/cm³
g = 9.8 N/kg
We need to convert mm to m and g/cm³ to kg/m³
Therefore;
Height = 636.2 mm ÷1000
= 0.6362 m
Density = 0.73 g/cm³ × 1000 kg/m³
= 730 kg/m³
Then, we can calculate the pressure;
Pressure = 0.6362 m × 730 kg/m³ × 9.8 N/kg
= 4551.3748 pascals
= 4551.37 Pascals
Therefore, the pressure of the column of decane is 4551.37 Pascals
Answer:
The seven crystal systems are a method of classifying crystals according to their atomic lattice or structure. The atomic lattice is a three dimensional network of atoms that are arranged in a symmetrical pattern. The shape of the lattice determines not only which crystal system the stone belongs to, but all of its physical properties and appearance. In some crystal healing practices the axial symmetry of a crystal is believed to directly influence its metaphysical properties. For example crystals in the Cubic System are believed to be grounding, because the cube is a symbol of the element Earth.
