Stells [14]

Answer:

39.13

Explanation:

To find that atomic mass of this potassium, we follow the steps below:

 Given parameters:

Abundance of K - 39  = 93.26%

Mass of K - 39  = 39

Abundance of K - 41  = 6.73%

Mass of K - 41 = 41

To find the average atomic mass;

Average atomic mass  =( mass x abundance of k -39 ) +( mass abundance of k- 41)

Average atomic mass =  (39 x  93.26%) + (41 x6.73%  )  = 39.13

22.6 grams of mercury ii nitrate, hg(no3)2 reacts with an excess of potassium, k. how many grams of mercury is formed? the other
pentagon [3]

Mass = 14.0 g of mercury is formed, 22.6 grams of mercury nitrate, hg(no3)2 reacts with an excess of potassium, k.

An inorganic substance with the formula Hg(NO3)2xH2O is mercury nitrate. Hot, concentrated nitric acid is used to process mercury to create it. By using X-ray crystallography, neither anhydrous nor monohydrate have been verified. The drug might have an impact on the kidneys, peripheral nervous system, and central nervous system. Ataxia, tremors. Given data: Mass of mercury nitrate = 22.17 g, Mass of mercury formed = ?

Solution:

Chemical equation:

Hg(NO₃)₂ + 2K    →    2KNO₃ + Hg

Number of moles of mercury nitrate:, Number of moles = mass/molar mass, Number of moles = 22.17 g / 324.6 g/mol, Number of moles = 0.07 mol, Now we will compare the moles of Hg(NO₃)₂ and mercury.

             Hg(NO₃)₂       :        Hg

                 1                :          1

              0.07             :       0.07

Mass of mercury: Mass = number of moles × molar mass, Mass = 0.07 mol × 200.6 g/mol

Mass = 14.0 g

Burning, cooking

Explanation:

Chemical changes that happens in school are:

Cooking of meals

 Burning of wastes

 Chemical reactions in laboratories

Rusting of iron used in construction

  • A chemical change is a change that produces new kinds of substances.
  • These changes are usually accompanied by energy and mass changes.
  • Most of such changes are not reversible.

Chemical changes are driven by change in chemical properties of matter.

In a school, iron components might begin to rust. This is a chemical change.
