Answer:

32.3 dm³

Explanation:

Data given:

no. of molecules of Cl₂ = 8.7 x 10²³

Volume of chlorine gas (Cl₂) = ?

Solution:

First we have to find number of moles

For this formula used

    no. of moles = no. of molecules / Avogadros number

    no. of moles = 8.7 x 10²³ / 6.022 x 10²³

    no. of moles = 1.44 moles

Now we have to find volume of the gas

for this formula used

                      no. of moles = volume of gas / molar volume

molar volume = 22.4 dm³/mol

Put values in above equation

                 1.44 moles = volume of Cl₂ gas / 22.4 dm³/mol

rearrange the above equation

                 volume of Cl₂ gas = 1.44 moles x 22.4 dm³/mol

                volume of Cl₂ gas =  32.3 dm³

Limescale removers contain sulfamic acid, H3NSO3, which reacts with minerals in hard water
I am Lyosha [343]

Answer:

0.375 moles of CaCO₃ are required

Explanation:

Given data:

Number of moles of sulfamic acid = 0.75 mol

Number of moles of calcium carbonate required = ?

Solution:

Chemical equation:

2H₃NSO₃ + CaCO₃     →        Ca(SO₃NH₂)₂ + CO₂ + H₂O

Now we will compare the moles of H₃NSO₃  and CaCO₃ .

                H₃NSO₃           :            CaCO₃  

                     2                 :             1

                   0.75              :           1/2×0.75 = 0.375 mol

Thus, 0.375 moles of CaCO₃ are required.

Calculate the value of [N2]eq if [H2]eq = 2.0 M, [NH3]eq = 0.5 M, and Kc = 2.N2(g) + 3 H2(g) ↔ 2 NH3(g)0.062 M62.5 M0.40 M0.016
Sloan [31]

Answer:

[ N₂(g) ]  = 0.016 M

Explanation:

N₂(g) + 3 H₂(g) ↔ 2 NH₃(g)

The equilibrium constant for the above reaction , can be written as the product of the concentration of product raised to the power of stoichiometric coefficients in a balanced equation of dissociation divided by the product of the concentration of reactant raised to the power of stoichiometric coefficients in the balanced equation of dissociation .  

Hence ,  

Kc = [ NH₃ (g) ]² / [ N₂(g) ]  [ H₂(g) ]³

From the question ,

[ NH₃ (g) ] = 0.5 M

[ N₂(g) ] = ?

[ H₂(g) ] = 2.0 M

Kc = 2

Now, putting it in the above equation ,  

Kc = [ NH₃ (g) ]² / [ N₂(g) ]  [ H₂(g) ]³

2 =  [ 0.5 M ]² / [ N₂(g) ]  [ 2.0 M ]³

[ N₂(g) ]  = 0.016 M .
