In a mixture of He, Ne, and Kr the total pressure is 125 kPa. The partial
tatiyna

Answer:

Partial pressure of He = 73 kPa

Explanation:

Given:

Total pressure = 125 kPa

Partial  pressure of Ne = 31 kPa

Partial pressure of Kr = 21 kPa

Find:

Partial pressure of He

Computation:

Total pressure = Partial  pressure of Ne + Partial  pressure of Kr + Partial  pressure of He

125 kPa = 31 kPa + 21 kPa + Partial pressure of He

Partial pressure of He = 73 kPa

Draw and label the parts of a helium atom. Include the mass and charge of each subatomic particle.
mihalych1998 [28]

Explanation:

Helium is the second element on the periodic table.

  Information about helium:

  • it belongs to group O on the periodic table
  • it is has an atomic number of 2
  • Helium exists naturally as gas and it is nonreactive.

  To write an atom we use this format:

                                     ₙᵇGˣ

   G is the symbol of the atom

   n is the atomic number  

   b is the mass number

    x is the charge on the atom

Using the periodic table as guide

    Symbol of helium is He

     Atomic number of helium is 2

     mass number of helium is 4

     charge on helium atom is 0

                              ⁴₂He

Every atom contains protons, neutrons and electrons;

   Electrons are negatively charged. For a neutral atom, the number of electrons is the same as that of protons.

   Protons are positively charge particles in an atom. The atomic number is the number of protons in an atom.

   neutrons do not have charges.

 

   Helium has:

        Number of protons = 2

        Number of electrons = 2

        Number of neutrons = 2

Mass of each subatomic particle:

      1 electron = 9.11 x 10⁻³¹kg

      2 electrons = 1.82 x 10⁻³⁰kg  

     Protons and neutrons have the same mass:

           1 proton = 1.67 x 10⁻²⁷kg

           2 protons = 3.34 x 10⁻²⁷kg

           2 neutrons = 3.34 x 10⁻²⁷kg

2. Why is the lonic compound Nacl (table salt) able to dissolve in a glass of the molecular compound water (H20)? (3 points)
melomori [17]

Answer:

The correct answer is C ions from the solute molecules have a strong attraction to the polar solvent molecules.

Explanation:

NaCl or Sodium chloride is an ionic compound which easily get dissolved in polar molecular compound such as water(H2O).

      Both NaCl and H2O are polar compound because the atoms that forms NaCl and H2O have vast difference in their electronegativities.As a result the bonding electrons in both NaCl and H2O are not equally shared.

     NaCl get dissolved in water molecules by dipole dipole interaction.
