Use the dichotomous key below to identify the cell type.
xenn [34]

The dichotomous key is not given here, however, the correct dichotomous key is as follows:

step- 1a cell has a nucleus and organelles - go to step 2

        1b cell has no nucleus or organelles - bacterial cell

step- 2a cell has a cell wall - go to step 3

         2b cell has no cell wall - animal cell

step-  3a cell has chloroplasts - plant cell

3b cell has no chloroplasts - fungal cell

Using this dichotomous key the cell can be identified as - Fungal cell.

A dichotomous key is an essential scientific tool that is used to find out the various kinds of organisms on their observable traits. Dichotomous keys have a series of statements with two different choices in each step that will take the student or user to the correct identification.

Identification of the given cell:

1. Follow step 1.

  • If cells have a nucleus and organelles - yes then go to step 2

2. follow step 2.

  • 2a. if cell has a cell wall - yes go to step 3

3. follow step 3.

  • 3a. if cell has chloroplasts - no then fungal cell

Fungal cells have a nucleus and cell organelles enclosed with a cell wall around the plasma membrane but do not have chloroplast.

Thus, Using this dichotomous key the cell can be identified as - Fungal cell.

In pure water at 25 °C, the concentration of a saturated solution of CuF2 is 7.4 × 10−3 M. If measured at the same temperature,
Romashka-Z-Leto [24]

Answer:

The concentration of a saturated solution of CuF₂ in aqueous 0.20 M NaF is  4.0×10⁻⁵ M.

Explanation:

Consider the ICE take for the solubility of the solid, CuF₂ as:

                                  CuF₂    ⇄     Cu²⁺ +    2F⁻

At t=0                            x                 -              -

At t =equilibrium      (x-s)                s           2s          

The expression for Solubility product for CuF₂ is:

K_{sp}=\left [ Cu^{2+} \right ]\left [ F^- \right ]^2

K_{sp}=s\times {2s}^2

K_{sp}=4s^3

Given  s = 7.4×10⁻³ M

So, Ksp is:

K_{sp}=4\times (7.4\times 10^{-3})^3

K_{sp}=4\times (7.4\times 10^{-3})^3

Ksp = 1.6209×10⁻⁶

Now, we have to calculate the solubility of CuF₂ in NaF.

Thus, NaF already contain 0.20 M F⁻ ions

Consider the ICE take for the solubility of the solid, CuF₂ in NaFas:

                                  CuF₂    ⇄     Cu²⁺ +    2F⁻

At t=0                            x                 -            0.20

At t =equilibrium      (x-s')             s'         0.20+2s'         

The expression for Solubility product for CuF₂ is:

K_{sp}=\left [ Cu^{2+} \right ]\left [ F^- \right ]^2

1.6209\times 10^{-6}={s}'\times ({0.20+2{s}'})^2

Solving for s', we get

<u>s' = 4.0×10⁻⁵ M</u>

<u>The concentration of a saturated solution of CuF₂ in aqueous 0.20 M NaF is  4.0×10⁻⁵ M.</u>

Determine the maximum amount of Fe that was produced during the experiment. Explain how you determined this amount
VladimirAG [237]

The number of moles of iron produced can be obtained by the use of  stoichiometry.

<h3>What is stoichiometry?</h3>

The term stoichiometry has to do with mass - mole or mass - volume relationships. Stoichiometric relationships could be used to determine the amount of substance.

Now the reaction equation as well as other details are not shown in this question hence a numerical anwer can not be provided. As such, we can know that the balanced reaction equation can always be used to obtain the amount of iron by stoichiometry.
