Answering the question, a plant root is an example of an organ

Plant consist of different organs, which include leaves, stem, reproductive organs, and roots. All the organs play a different role in the plant.

<h2>Further Explanation</h2>

The functions of the different organs present in the plant include:

  • The roots absorb water and inorganic nutrients from the soil.
  • Leaves help by capturing sunlight and provide food for the plants through the process of photosynthesis. Also, the tiny holes in the leaves serve as the exit point for waste products
  • The stem serves as a support for the leaves and flowers and also helps to elevate leaves. The stem also helps in moving water and nutrients through the roots and leaves
  • The plant reproductive organ enables the plant to generate new plants

The plant consist of many cells and in a tissue, there are cells that work together, particularly similar cells. Also, each of the tissues carries out different functions.

For example, the dermal tissue serves as protection to plant and also monitor the interaction within the plant environment. Dermal tissue also prevents the plants from losing water.

All the organs that a plant possesses allow it to perform the important process of life.

The processes of life are seven, which include

  • Movement
  • Respiration
  • Senility
  • Growth
  • Reproduction
  • Excretion
  • Nutrition

The solubility product of PbI2 is 7.9x10^-9. What is the molar solubility of PbI2 in distilled water?
Agata [3.3K]

<u>Answer:</u> The molar solubility of PbI_2 is 1.25\times 10^{-3}mol/L

<u>Explanation:</u>

Solubility is defined as the maximum amount of solute that can be dissolved in a solvent at equilibrium.

Solubility product is defined as the product of concentration of ions present in a solution each raised to the power its stoichiometric ratio.

The balanced equilibrium reaction for the ionization of calcium fluoride follows:

PbI_2\rightleftharpoons Pb^{2+}+2I^-

                s       2s

The expression for solubility constant for this reaction will be:

K_{sp}=[Pb^{2+}][I^-]^2

We are given:

K_{sp}=7.9\times 10^{-9}

Putting values in above equation, we get:

7.9\times 10^{-9}=(s)\times (2s)^2\\\\7.9\times 10^{-9}=4s^3\\\\s=1.25\times 10^{-3}mol/L

Hence, the molar solubility of PbI_2 is 1.25\times 10^{-3}mol/L

How many half-lives will pass by the time 1.56% of I-131 is present? B. Approximately how many days does that equal? *
serg [7]

Answer: Hmmmmm that's crazy....

There are a couple of equations one could use for this type of problem, but I find the following to be the easiest to use and to understand.

Fraction remaining (FR) = 0.5n

n = number of half lives that have elapsed

In this problem, we need to find n and are given the FR, which is 1.56% or 0.0156 (as a fraction).

0.0156 = 0.5n

log 0.0156 = n log 0.5

-1.81 = -0.301 n

n = 6.0 half lives have elapsed

Explanation:

Just wanted to help. Hopefully it's correct wouldn't want to waster your time ;)

Nikolay [14]
Antifreeze is an additive in water-based liquid to lower down the freezing point of such liquid. It is used to make use of the colligative properties of solutions specifically freezing-point depression for cold climate and boiling-point elevation to allow higher coolant temperature.
