Net ionic equation for Calcium hydroxide reacting with ammonium Chloride?

1 answer:

Georgia [21]2 years ago

7 0

Answer:

<em>Step 1: Write the balanced chemical equation with the states first:</em>

Ca(OH)₂ (aq) + 2NH₄Cl (aq) → CaCl₂ (aq) + 2NH₃ (g) + 2H₂O (l)

<em>Step2: Write the complete ionic equation, break only the aqueous ones only :</em>

Ca²⁺ + 2OH⁻ + 2NH₄⁺ + 2Cl⁻ → Ca⁺² + 2Cl⁻ + 2NH₃ (g) + 2H₂O (l)

<em>Step 3: cancel the spectator ions ( the ions which stay the same like calciumn and chlorine ions here)</em>

<h2> 2OH⁻ + 2NH₄⁺ → 2NH₃ (g) + 2H₂O (l)</h2>

If water has no color, why does your hair get darker when water makes contact with it?

Simora [160]

Answer:

The water makes your individual hairs stick close together. ... When more light is absorbed by your wet hair, less light gets reflected back to your eyes. The result is that your hair appears darker than when it's dry.

The vaporization of 1 mole of liquid water (system) at 100.9 C, 1.00 atm, is endothermic.

yan [13]

Answer:

a) The work done is 10.0777 kJ

b) The water's change in internal energy is -122.1973 kJ

Explanation:

Given data:

1 mol of liquid water

T₁ = temperature = 100.9°C

P = pressure = 1 atm

Endothermic reaction

T₂ = temperature = 100°C

1 mol of water vapor

VL = volume of liquid water = 18.8 mL = 0.0188 L

VG = volume of water vapor = 30.62 L

3.25 moles of liquid water vaporizes

Q = heat added to the system = -40.7 kJ

Questions: a) Calculate the work done on or by the system, W = ?

b) Calculate the water's change in internal energy, ΔU = ?

Heat for 3.25 moles:

$Q_{1} =3.25*(-40.7)=-132.275kJ$

The work done:

$W=-nP*delta(V)=-3.25*101.33*(0.0188-30.62)=10077.6637J=10.0777kJ$

The change in internal energy:

$delt(U)=W+Q_{1} =10.0777-132.275=-122.1973kJ$
