The right answer is animal-like.

Protists are unicellular living organisms about 0.1 mm in size, such as amoeba, paramecium and euglena.

Protists are a paraphyletic group in the phylogenetic classification. They were, in classical classification, the fourth reign of the domain of eukaryotes but they are currently defined by exclusion, that is to say that they are all eukaryotes belonging neither to mushrooms nor to plants or animals.

iris [78.8K]

Answer:

See explanation for accurate matching

Explanation:

The mass of a salt in grams that will dissolve in 100 mL of water.--- solubility

A solution that has dissolved the maximum amount of a compound at a given temperature.---- saturated solution

Any further addition of salt will remain undissolved-----supersaturated solution

The maximum number of moles of a salt that will dissolve in 1 L of solution----molarity

A decrease in the solubility of an ionic compound as a result of the addition of a common ion..... Common ion effect

The product of the molarities of the dissolved ions, raised to a power equal to the ion's coefficient in the balanced chemical equation........solubility product.

olasank [31]

Answer:

Radon

Explanation:

One element that will have similar property as an atom with 118 protons is Radon because it will belong to the p-block and the noble gas group.

The element will follow atomic number 117 which is already in the 7th group on the periodic table.

  • Generally, on the periodic table, elements in the same group will have the same chemical property.
  • The valency of most elements determines their chemical behavior.
  • Since our mystery element is in the 8th group, noble gas group, it will mostly behave like any of the elements in the group.

viktelen [127]

Actual question from source:-

A 3.96x10-4 M solution of compound A exhibited an absorbance of 0.624 at 238 nm in a 1.000 cm cuvette.  A blank had an absorbance of 0.029.  The absorbance of an unknown solution of compound A was 0.375.  Find the concentration of A in the unknown.

Answer:

Molar absorptivity of compound A = 1502.53\ {Ms}^{-1}

Explanation:

According to the Lambert's Beer law:-

A=\epsilon l c

Where, A is the absorbance

 l is the path length  

\epsilon is the molar absorptivity

c is the concentration.  

Given that:-

c = 3.96\times 10^{-4}\ M

Path length = 1.000 cm

Absorbance observed = 0.624

Absorbance blank = 0.029

A = 0.624 - 0.029 = 0.595

So, applying the values in the Lambert Beer's law as shown below:-

0.595=\epsilon\times 1.000\ cm\times 3.96\times 10^{-4}\ M

\epsilon=\frac{0.595}{3.96\times 10^{-4}}\ {Ms}^{-1}=1502.53\ {Ms}^{-1}

<u>Molar absorptivity of compound A = 1502.53\ {Ms}^{-1}</u>
