10.0 g of gaseous ammonia and 6.50 g of oxygen gas are introduced into a previously evacuated 5.50 L vessel. If the ammonia and
Shalnov [3]

Answer:

The density is 3g/L

Explanation:

The reaction that occurs in the vessel is:

4 NH₃ + 5 O₂ → 4 NO + 6 H₂O

10,0g of NH₃ are:

10,0g * \frac{1mol}{17,031g} = 0,587 moles

6,50 g of O₂ are:

6,50g * \frac{1mol}{32g} = 0,203 moles

For a complete reaction of O₂ there are necessaries:

0,203 mol * \frac{4molNH_{3}}{5molO_{2}}= 0,163 moles of NH_{3}

O₂ is limiting reactant. The excess moles of NH₃ are:

0,587 - 0,163 = <em>0,424 moles of NH₃</em>

These moles are:

0,424mol * \frac{17,031g}{1mol} = <em>7,22g of NH₃</em>

Knowing O₂ is limiting reactant, mass of NO and H₂O are:

0,203molO_{2}*\frac{4molNO}{5molO_{2}}*\frac{30,01g}{1molNO} = <em>4,87g of NO</em>

0,203molO_{2}*\frac{6molH_{2}O}{5molO_{2}}*\frac{18,02g}{1molH_{2}O} = <em>4,39g of H₂O</em>

The total mass is: 7,22g + 4,87g + 4,39g = 16,48g ≡ <em>16,5g </em>

<em>-</em><em>The same mass add in the first. By matter conservation law-</em>

As vessel volume is 5,50L, density is:

16,5g/5,50L = <em>3g/L</em>

I hope it helps!

What is the difference between electronegativity and ionization energy
Katena32 [7]

Answer:

These properties are basically the inverse of each other.

Explanation:

  • Electronegativity is the tendency of an atom to attract an electron and make it a part of its orbital.

        Ionization enthalpy, is the energy required to remove an electron from                        an atom.

  • More electronegative atoms have high ionization enthalpies If the energy required to remove an electron is less, i.e. the atom has more tendency to give electron, it would thus have less tendency to take electron.
  • Values and tendency of electronegativity in the periodic table: In general, the electronegativity of a non‐metal is  larger than that of metal. For the elements of one period the electronegativities increase from  left to right across the periodic table. For the elements of one main group the electronegativities  decrease from top to bottom across the periodic table. To the subgroup elements, there’s no  regular rule.
  • Values and tendency of ionization potential in the periodic table: The first ionization energy is the energy which is  required when a gaseous atom/ion loses an electron to form a gaseous +1 valence ion. The  energy which is required for a gaseous +1 valence ion to loose an electron to form a gaseous +2  valence ion, is called the second ionization energy of an element.  In general, the second ionization energy is higher than the first ionization energy of an element. The first ionization energies of the elements of one period increase from the left to the right  across the periodic table. According to the elements of main group, the first ionization energies  generally decreases from top to bottom across the periodic table.

Answer:

Structural formula

Explanation:

This is because structural formula is use to show or indicate chemical bonds that are present between atoms of molecules. structural formula comprises of symbols that represent the atoms which are connected by short lines which indicate the presence chemical bonds which could be single line, double lines or even triple lines.
