3 0

Answer:

Kingdom Fungi refers to the group of eukaryotic organisms like fungi, mushrooms, molds and yeasts.

Explanation:

The fungi kingdom is made up of eukaryotic organisms whose cell walls are made of chitin.

Next I will name <u>some characteristics</u> of these organisms:

  • They are not plants or animals .
  • They are responsible for absorbing nutrients from other organisms, which they use as food .
  • Some, like mushrooms and yeast, are edible.
  • They present cellular orguils and vacuoles .
  • They lack chloroplasts .
  • They produce spores .
  • They are able to break down dead matter .
  • They develop in humid and dark areas .
  • Penicillin is obtained from these organisms.

When 16.0 g of an unknown compound (a nonelectrolyte) are dis solved in exactly 800. g of water, the solution has a freezing poi
dexar [7]

Answer:

A. 266g/mol

Explanation:

A colligative property of matter is freezing point depression. The formula is:

ΔT = i×Kf×m <em>(1)</em>

Where:

ΔT is change in temperature (0°C - -0,14°C = 0,14°C)i is Van't Hoff factor (1 for a nonelectrolyte dissolved in water), kf is freezing point molar constant of solvent (1,86°Cm⁻¹) and m is molality of the solution (moles of solute per kg of solution). The mass of the solution is 816,0g

Replacing in (1):

0,14°C = 1×1,86°Cm⁻¹× mol Solute / 0,816kg

<em>0,0614 = mol of solute</em>.

As molar mass is defined as grams per mole of substance and the compound weights 16,0g:

16,0g / 0,0614 mol = 261 g/mol ≈ <em>A. 266g/mol</em>

I hope it helps!

What are valence electrons ?
Arada [10]

Answer:In chemistry, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

Explanation: hope this helped

The isotope 106 46Pd (106 on top and 46 on bottom)
vazorg [7]

Answer:

4. 60 neutrons.

Explanation:

The given isotopes;

         ¹⁰⁶₄₆Pd

In this isotope, we can deduce that the mass number is the superscript and the atomic number is the subscript;

     Mass number  = 106

     Atomic number  = 46

Mass number is the number of protons and neutrons in an atom;

       Mass number = Protons + neutrons

Atomic number is the number of protons

   

So,  Number of protons  = 46

Number of neutrons  = Mass number  - Atomic number

                                    = 106  - 46

                                     = 60

Number of neutrons  = 60
