liubo4ka [24]

Answer: Anna stated that ionic compounds have high melting point and low boiling point. The error in the statement is that ionic compound have low boiling point, instead ionic compounds have high boiling point, because in an ionic compound, the force of attraction working between two ions is very strong and hence the bonds present are very strong, and a lot of energy is needed to break them

Two closed vessels contain chlorine gas at the same conditions of temperature and
wariber [46]

Answer:12 mol

Explanation: both vessels are at the same temp and pressure (and the pressure is low and/or the temperature high).

6.7mol per 1.3L = 6.7/1.3 mol/L

so in 2.33L = 6.7*2.33/1.3 = 12 mol

Answer:

The solution's new volume is 1.68 L

Explanation:

Dilution is the procedure to prepare a less concentrated solution from a more concentrated one, and simply consists of adding more solvent. So, in a dilution the amount of solute does not vary, but the volume of the solvent varies.

In summary, a dilution is a lower concentration solution than the original.

The way to do the calculations in a dilution is through the expression:

Ci*Vi=Cf*Vf

where C and V are concentration and volume, respectively; and the i and f subscripts indicate initial and final respectively.

In this case, being:

  • Ci= 7 M
  • Vi= 0.60 L
  • Cf= 2.5 M
  • Vf=?

Replacing:

7 M*0.60 L= 2.5 M* Vf

Solving:

Vf=\frac{7 M*0.60 L}{2.5 M}

Vf= 1.68 L

<u><em>The solution's new volume is 1.68 L</em></u>

What is Δn for the following equation in relating Kc to Kp?<br> 2 SO2(g) + O2(g) ⇌ 2 SO3(g)
swat32

Answer:

Δ N = -1

Explanation:

Step 1: Data given

2 SO2(g) + O2(g) ⇌ 2 SO3(g)

For 2 moles of SO2 we need 1 mol of O2 to produce 2 moles of SO3

Step 2: Calculate Δ

Δ N  wNill be the sum of moles of products minus the sum of moles of reactants.

Number of moles of products = number of moles of SO3 = 2

Number of moles of reactants = number of moles of SO2 + number of moles of O2 = 2 + 1 = 3

Δ N = 2 - 3 = -1
