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
Lustrous (shiny)
Good conductors of heat and electricity.
High melting point.
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
Litmus solution is generally a purple dye. The solution of Litmus is extracted from lichens. The Litmus solution is used as an indicator to determine the acidic and basic nature of a solution.Lichens plants belonging to the class of Thallophyta. The litmus solution method involves the grinding and crushing of lichens. In order to get the desired litmus solution, such dyes are then introduced to neutral water.
Answer:
a) 74.87 % carbon
Explanation:
Molecular mass of CH₄ is 16.042 g / mole.
Now we divide the following reasoning for 1 mole of methane:
if in 16.042 g of CH₄ there are 12.01 g of carbon
then in 100 g of CH₄ there are X g of carbon
X = (100 × 12.01) / 16.042= 74.87 % carbon
