Answer:
T₂ = 687.6 K
Explanation:
Given data:
Initial pressure = 108 Kpa
Initial temperature = 20°C
Final temperature = ?
Final pressure = 2.50 atm
Solution:
Initial pressure = 108 Kpa = 108/101 = 1.06588 atm
Initial temperature = 20°C = 20+273.15 = 293.15 k
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1.06588 atm / 293.15 K = 2.5 atm/T₂
T₂ = 2.5 atm ×293.15 K / 1.06588 atm
T₂ = 732.875 atm. K /1.06588 atm
T₂ = 687.6 K
Answer: The metalloids are a unique group of elements that share properties of both metals and nonmetals.
Explanation: They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
Because it looses it's science-street-cred if it can't be replicated.
Essentially.
If you can replicate an experiment you can prove that the results are not just a stroke of luck or happening by chance, but instead that the variables are causing the results and they will always as long as the factors of the experiment remain the same. That is the definition of a <em>scientific</em> experiment.
