Ammonium carbonate decomposes upon heating according to the following balanced equation:

Ugo [173]

Answer : The total volume of gas produced are, 11.5 L

Explanation :

First we have to calculate the moles of ammonium carbonate.

$\text{Moles of }(NH_4)_2CO_3=\frac{\text{Mass of }(NH_4)_2CO_3}{\text{Molar mass of }(NH_4)_2CO_3}$

Molar mass of $(NH_4)_2CO_3$ = 96.094 g/mol

$\text{Moles of }(NH_4)_2CO_3=\frac{11.9g}{96.094g/mol}$

$\text{Moles of }(NH_4)_2CO_3=0.124mol$

Now we have to calculate the moles of total gas.

The given balanced chemical reaction is:

$(NH_4)_2CO_3(s)\rightarrow 2NH_3(g)+CO_2(g)+H_2O(g)$

From the balanced chemical reaction we conclude that,

As, 1 mole of $(NH_4)_2CO_3$ react to give 4 mole of gas

So, 0.124 mole of $(NH_4)_2CO_3$ react to give $0.124\times 4=0.496$ mole of gas

Now we have to calculate the volume of gas.

Using ideal gas equation:

$PV=nRT$

where,

P = Pressure of gas = 1.05 atm

V = Volume of gas = ?

n = number of moles = 0.496 mole

R = Gas constant = $0.0821L.atm/mol.K$

T = Temperature of gas = $24.0^oC=273+24.0=297.0K$

Putting values in above equation, we get:

$1.05atm\times V=0.496mole\times (0.0821L.atm/mol.K)\times 297.0K$

$V=11.5L$

Thus, the total volume of gas produced are, 11.5 L

Are shrubs and small animals primary secondary or both? Are small trees primary secondary or both? These are both separate quest

In-s [12.5K]

Answer:

1.

shrubs are producers.
small animals are primary if they eat plants only.
they're both if the consumer is omnivorous

2. most plants , including trees, are producers so they can't be consumers.

only rare plants like the venus fly trap is a consumer because they eat bugs.

PLS help, 20 points for you<br><br> I need a Molecular, and Ionic equations:<br> H2CO3 + LiOH -

STatiana [176]

The molecular equation of H₂CO₃ and LiOH:

H₂CO₃ (aq) + 2LiOH (aq) → Li₂CO₃ (aq) + 2H₂O (l)

The net ionic equation of the reaction of H₂CO₃ and LiOH:

H⁺ (aq) + OH⁻ (aq) → H₂O (l)

<h3>What are the net ionic equations?</h3>

The net ionic equation of a chemical reaction can be described as an equation that expresses only those ions, elements, or compounds, that directly contributed to that chemical reaction.

The chemical equation for the reaction of H₂CO₃ and LiOH:

H₂CO₃ (aq) + LiOH (aq) → Li₂CO₃ (aq) + 2H₂O (l)

The complete ionic equation for the above reaction H₂CO₃ and LiOH is:

2H⁺ (aq) + CO₃²⁻ (aq) + 2Li⁺ (aq) + 2OH⁻ → 2Li⁺ (aq) + CO₃²⁻(aq) + 2H₂O (l)

In the ionic equation, the Lithium and carbonate ions appear unchanged on both sides of the equation. When we mix the two solutions, neither the Lithium nor carbonate ions participate in the reaction. So Lithium and carbonate ions can be eliminated from the ionic equation.

H⁺ (aq) + OH⁻ (aq) → H₂O (l)

The Ksp of the solution is 1.97 * 10^-9.

The pH is defined as the hydrogen ion concentration of the solution. Now we have the pH of the solution as 10.9.

We know that;

pOH = 14 - pH

pOH = 14 - 10.9

pOH = 3.1

[OH^-] = Antilog [-3.1]

[OH^-] =7.9 * 10^-4 M

Now

Ksp = [M^2+] [2OH^-]^2

Ksp = s * (2s)^2

Ksp = 4s^3

Now s = 7.9 * 10^-4 M

Ksp = 4(7.9 * 10^-4)^3

Ksp = 1.97 * 10^-9
