This reaction is exothermic because the system (the aqueoud solution) is transferring heat to its surroundings (the calorimeter) so this eliminates two responses. Since the heat is being transferred to the surroundings, the water that's in the calorimeter in this case, it is causing the water molecules to heat up and thus an increase in the kinetic energy of the water molecules since temperature affects kinetic energy
Gold (III) nitrate in an aqueous solution is hydrolyzed with formation of gold (III) metahydroxide.
Au(NO₃)₃ → Au³⁺(aq) + 3NO₃⁻(aq)
Au³⁺ + H₂O ⇄ AuOH²⁺ + H⁺
AuOH²⁺ + H₂O ⇄ Au(OH)₂⁺ + H⁺
Au(OH)₂⁺ + H₂O → AuOOH·H₂O(s) + H⁺
Au(NO₃)₃(aq) + 2H₂O(l) = AuOOH(s) + 3HNO₃(aq)
Answer:
First off Life sciences are anything concerned with the study of a living organisms. So ones that would be included would be, microbiology biology, botany, zoology, ecology, genetics and medicine, from what the dictionary states
Explanation:
Biology is the natural science that studies life and living organisms. Which also includes molecular interactions, including their physical structure.
Genetics, is the study of heredity and or the variation of inherited characteristics that we get from family.
Microbiology, is the branch of science which deals with microorganisms.
Let me know if this helps, if not I'll continue researching.
<span>The type of map that shows the type and age of
rocks in an area is called a Geologic Map. A geologic map is a special-purpose
map that represents the distribution of diverse types of rocks, as well as
locations of different geologic structures such as faults and folds. This map
is the main source of information for various aspects of land-use planning,
especially in the placement of transportation systems and buildings. Although
they are typically depicted as two-dimensional, they can also be illustrated in
its third or fourth dimension depending on the type of information needed to be
taken. </span>
Answer:
<h2>pH = 3.9</h2><h2>pOH = 10.1</h2>
Explanation:
Since 
is a weak acid to find the pH of we use the formula
where
Ka is the acid dissociation constant
c is the concentration
From the question
Ka of = 1.75 × 10^-5
c = 1.00 × 10-³M
Substitute the values into the above formula and solve for the pH
That's
We have the answer as
<h3>pH = 3.9</h3>
To find the pOH we use the formula
pH + pOH = 14
pOH = 14 - pH
pOH = 14 - 3.9
We have the answer as
<h3>pOH = 10.1</h3>
Hope this helps you
