22. Ano ang iodine? mga pagkaing mayaman sa iodine?

Answer:

Ano ang iodine?

Ang iodine ay isang klase ng mineral na importante sa produksyon ng mga hormone na nagmula sa glandulang thyroid. Ang mga hormone na ito ay ang responsable sa pag-regulate ng ng takbo ng thyroid, pagsuporta sa maayos na metabolism, pagtulong sa paglaki ng katawan at pag-iwas sa mga chronic diseases gaya ng cancer. Ang katawang ng isang tao mayroong 20 hanggang 30 miligrams ng iodine na matatagpuan sa thyroid gland, sa baba ng tinatawag na voice box. Ang ilang iodine ay nasa mammary glands, salivary glands, stomach lining at dugo.

27. Determine the % by mass of 2 mL iodine in 8mL H20. formula and solution.

To determine the percent by mass of iodine in a solution, you will first need to know the mass of iodine and the mass of the solvent (in this case, water).

Here's one way to approach the problem:

First, you'll need to know the density of iodine (the mass of a certain volume of iodine) and the density of water. According to the Periodic Table of Elements, the density of iodine is 4.93 g/mL, and the density of water is 1.00 g/mL.

Using this information, you can calculate the mass of 2 mL of iodine by multiplying the volume (2 mL) by the density (4.93 g/mL).

mass of iodine = 2 mL x 4.93 g/mL = 9.86 g

Next, you can calculate the mass of 8 mL of water by multiplying the volume (8 mL) by the density (1.00 g/mL).

mass of water = 8 mL x 1.00 g/mL = 8.00 g

The total mass of the solution is the sum of the mass of iodine and the mass of water.

total mass = 9.86 g + 8.00 g = 17.86 g

To determine the percent by mass of iodine in the solution, divide the mass of iodine by the total mass of the solution and multiply by 100:

% iodine = (mass of iodine / total mass) x 100

% iodine = (9.86 g / 17.86 g) x 100 = 55.37 %

So the percent by mass of iodine in this solution is 55.37 %.

Explanation:

The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).  The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.  (Atomic mass is also referred to as atomic weight, but the term "mass" is more accurate.)

For instance, it can be determined experimentally that neon consists of three isotopes:  neon-20 (with 10 protons and 10 neutrons in its nucleus) with a mass of 19.992 amu and an abundance of 90.48%, neon-21 (with 10 protons and 11 neutrons) with a mass of 20.994 amu and an abundance of 0.27%, and neon-22 (with 10 protons and 12 neutrons) with a mass of 21.991 amu and an abundance of 9.25%.  The average atomic mass of neon is thus:

0.9048 × 19.992 amu = 18.09 amu

0.0027 × 20.994 amu =   0.057 amu

0.0925 × 21.991 amu =   2.03 amu

       20.18 amu

 

The atomic mass is useful in chemistry when it is paired with the mole concept:  the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element.  Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.  The same concept can be extended to ionic compounds and molecules.  One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams.  One molecule of water (H2O) would weigh 18.02 amu (2×1.00797 amu for H + 15.9994 amu for O), and a mole of water molecules would weigh 18.02 grams.

The original periodic table of the elements published by Dimitri Mendeleev in 1869 arranged the elements that were known at the time in order of increasing atomic weight, since this was prior to the discovery of the nucleus and the interior structure of the atom.  The modern periodic table is arranged in order of increasing atomic number instead.
