Answer:
T₂ = 317.87 K
Explanation:
Given data:
Initial pressure = 15 atm
Final pressure = 16 atm
Initial temperature = 298 K
Final temperature = ?
Solution:
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:
15 atm / 298K = 16 atm/T₂
T₂ = 16atm × 298 K / 15 atm
T₂ = 4768 atm. K / 15 atm
T₂ = 317.87 K
True
As the shorter the bond, the stronger it is hence more energy will be required to overcome this bond
Answer:
Radium
Explanation:
It has the highest atomic number so it would have more shells, making it larger than the others.
Answer:
The answer to your question is: letter C) 5730
Explanation:
Data
Originally Carbon - 14 254 g
Currently Carbon - 14 127 g
Half-life of Carbon -14 is when half of the original amount of Carbon disintegrates.
Then, if originally there were 254 and now there are 127, only one half life passed.
Half life of carbon -14 is 5730 years old.
