It most likely would be "miscible" because "soluble" refers to something being able to dissolve in water, "insoluble" is something not being able to dissolve or mix such as oil and water and immiscible is something not being able to mix without forming layers.
Answer is: Miscible.

Compare 1 mole of H2, 1 mole of O2 and 1 mole of F2
likoan [24]

Explanation:

(a)  As per the mole concept, one mole of any atom contains 6.022 \times 10^{23} atoms or molecules, that is, Avogadro's number of atoms.

Therefore, 1 mole of H_{2} = 2 \times 6.022 \times 10^{23} molecules

                                           = 1.2044 \times 10^{23} molecules

   1 mole of O_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

   1 mole of F_{2} = 2 \times 6.022 \times 10^{23} molecules

                                    = 1.2044 \times 10^{23} molecules

Hence, there are equal number of molecules present in the given atoms.

(b)   Mass of each given atom will be calculated as follows.

                Mass = no. of moles × molar mass

As one molecule of H_{2} contains 2 atoms of hydrogen.

So, mass of 1 mole of H_{2} = 2 mol \times 1.008 g/mol

                                                     = 2.016 g

      mass of 1 mole of O_{2} = 2 mol \times 15.999 g/mol

                                                     = 31.996 g

      mass of 1 mole of F_{2} = 2 mol \times 18.998 g/mol

                                                     = 37.996 g

Thus, we can conclude that F_{2} has the greatest mass.

Be sure to answer all parts. the equilibrium constant (kp) for the reaction below is 4.40 at 2000. k. h2(g) + co2(g) ⇌ h2o(g) +
svetoff [14.1K]
When we have the balanced reaction equation is:

H2(g)  + CO2(g) ↔ H2O(g)  + CO (g)

a) first, to calculate ΔG° for the reaction: 

we will use this formula:

ΔG° = -RT㏑Kp

when R is R- rydberg constant = 8.314J/mol.K

and T is the temperature in Kelvin = 2000 K

and Kp = 4.4 

so, by substitution:

ΔG° = - 8.314 *2000 *㏑4.4

        = - 24624 J/mol = - 24.6 KJ/mol

b) to calculate ΔG so, we will use this formula:

ΔG = ΔG° + RT㏑Qp

So we need first, to get Qp from the reaction equation:

when Qp = P products / P reactants

                 =  PH2O*PCO / PH2 * PCO2

                 = (0.66 atm * 1.2 atm) / (0.25 * 0.78)

                 = 4.1 

so by substitution:

ΔG = -24624 + 8.314*2000*㏑4.1

      = -1162 J/mol = - 1.16 KJ/mol

If NaCl has a mass of 3.2g, what is the volume of chlorine gas at STP?
Shalnov [3]

Hey there!

Molar mass NaCl = 58.44 g/mol

58.44 g ----------------- 22.4 ( at STP )

3.2 g -------------------- Volume ??

Volume = ( 3.2 x 22.4 )  / 58.44

Volume = 71.68 / 58.44

Volume = 1.226 L

Hope this helps!

17.<br> What do you know about a chemical compound by looking at its chemical formula
Bas_tet [7]

Answer:

The number and the kinds of atoms in the compound

Explanation:

  • A chemical formula of a compound contains symbols o the atoms of the elements present in the compound as well as the number of atoms of each element in the form of subscripts.
  • Therefore it helps us to know the elements in a compound and the number of atoms in the compounds.
