Mama L [17]
<span>This can be solved using basic algebra. X equals the number of liters of 2% brine to add. Therefore we use this equation. 3 + 0.02x = 2.4 + 0.08x 0.6 = 0.6x x = 0..6/0.06 x = 10</span>

What's the balanced chemical equation of magnesium reacting with silver nitrate to produce silver and magnesium nitrate?
Strike441 [17]

The balanced equation is Mg + 2AgNO₃ ⟶ Mg(NO₃)₂ + 2Ag

Step 1. Write the <em>unbalanced equation </em>

Mg + AgNO₃ ⟶ Mg(NO₃)₂ + Ag

Step 2. Start with the<em> most complicated-looking formula</em> [Mg(NO₃)₂] and balance its atoms.

Mg: Already balanced —1 atom each side.

N: We need 2 N on the left. Put a 2 in front of AgNO₃.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + Ag

O: Already balanced —6 atom6 each side.

Step 3: Balance <em>Ag</em>

We have 2Ag on the left. We need 2Ag on the right.

1Mg + 2AgNO₃ ⟶ 1Mg(NO₃)₂ + 2Ag

denis23 [38]

Answer:

The maximum amount of solute that dissolves in a given amount of solvent and forms a stable solution is called the solubility of the solute

Explanation:

The maximum amount of solute that could be dissolved in a given amount of solvent is the solubility of the solute. It is the saturated solution's concentration from where a saturated solution can be defined as the one which already contains the maximum quantity of dissolved solute at a specified temperature, while an unsaturated solution is one with a capacity to dissolve more solutes

The water-gas shift reaction CO(g)+H2O(g)⇌CO2(g)+H2(g) is used industrially to produce hydrogen. The reaction enthalpy is ΔH∘=−4
denis23 [38]

Answer:

To increase the yield of H₂ we would use a low temperature.

For an exothermic reaction such as this, decreasing temperature increases the value of K and the amount of products at equilibrium. Low temperature increases the value of K and the amount of products at equilibrium.

Explanation:

Let´s consider the following reaction:

CO(g) + H₂O(g) ⇌ CO₂(g) + H₂(g)

When a system at equilibrium is disturbed, the response of the system is explained by Le Chatelier's Principle: <em>If a system at equilibrium suffers a perturbation (in temperature, pressure, concentration), the system will shift its equilibrium position to counteract such perturbation</em>.

In this case, we have an exothermic reaction (ΔH° < 0). We can imagine heat as one of the products. If we decrease the temperature, the system will try to raise it favoring the forward reaction to release heat and, at the same time, increasing the yield of H₂. By having more products, the value of the equilibrium constant K increases.
