The H+ concentration in the lake has increased as a result of the acid rain.
The original pH of the lake was 7, which mean the water is neutral, but due to the acid rain, it drops to 5. This means, that the water has become acidic and how have more hydrogen ion. The H+ concentration in the lake has 100 times compares with its original pH.
Answer:
<h2>117.94 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>117.94 moles</h3>
Hope this helps you
It’s g cause it’s closest to 10 which would make 40

Metallic bonds
Explanation:
The physical properties of metals such as malleability, ductility, electrical and thermal conductivity, luster e.t.c is controlled by metallic bonds.
- Metallic bonds join atoms of metals and alloys together.
- The formation of this bond type is favored by large atomic radius, low ionization energy and a large number of electrons in the valence shell.
- Metallic bond is actually an attraction between the positive nuclei of all closely packed atoms in the lattice and the electron cloud jointly formed by all atoms losing their outermost shell electrons.
