The pressure of the gas = 40 atm
<h3>Further explanation</h3>
Given
200 ml container
P = 2 atm
final volume = 10 ml
Required
Final pressure
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied

Input the value :
P₂ = P₁V₁/V₂
P₂ = 2 x 200 / 10
P₂ = 40 atm
You are looking for an element in the fourth period and a transition metal. As most have about 3 valence electrons. Gallium and Scandium work perfectly.
Answer:
A covalent bond
Explanation:
the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.

<h3>Answer</h3>
The chemicals that acid rain contains can have damaging effects on objects like buildings, monuments, statues, and cars.
Its components can make paint to be peel, stone construction appears old, worn down which reduces the architectural value and beauty.
<h2>Explanation</h2>
Depending on how acidic the rain is, it can obliterate these constructions to a brutal degree.
First, components like sulfurous, sulfuric and nitric acids mix with air and rain. Then they react with calcite or calcium-based compounds in marble and limestone and dissolve calcite.
The dry depositions of acidic particles contribute severely to the corrosion of construction materials, building paints, stones like marble, limestones and various type of granites.
Acid rains aggravate the life value of buildings and architectural structures.
