Answer:
V₂ =31.8 mL
Explanation:
Given data:
Initial volume of gas = 45 mL
Initial temperature = 135°C (135+273 =408 K)
Final temperature = 15°C (15+273 =288 K)
Final volume of gas = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 45 mL × 288 K / 408 k
V₂ = 12960 mL.K / 408 K
V₂ =31.8 mL
For Single Element Ions (e.g. K+ , Mg2+, P3-) To name positive (+) ions write the name as from the Periodic Table and add the word 'ion' afterwards. To name negative (-) ions write the name from the Periodic Table but replace the ending with 'ide'. Put the word 'ion' after the name.
Answer: The rock formed from cooling lava.
Explanation:Extrusive igneous rocks, also known as volcanic rocks, are formed at the crust's surface as a result of the partial melting of rocks within the mantle and crust.
Answer:
all non metals
Explanation:
iodine is a non metal, and if a metal had bonded with it, it would he considered a metal and non metal. But since two iodine atoms are bonded together, they are both non metals ( I2)
