Answer:
The volume will not change. This belongs in Ripley's Believe It or Not.
Explanation:
The combined gas law can be used to model both the initial (1) and ending (2) states of a gas when pressure (P), temperature (T) and/or volume (V) change, but the number of moles does not. Remember that temperature must always be in Kelvin.
P1V1/T1 = P2T2/T2
Rearranging for V2:
V2 = V1(T2/T1)(P1/P2)
I've arranged the pressure and temperature terms as ratios. This makes it easier to see what impact changes will have, plus the units conveniently cancel for both.
(V2) = (1 L)(T2/T1)(P1/P2)
We are told that P2 and T2 are both doubled:
(T2/T1) = 2
(P1/P2) = 1/2
V2 = (1 L)(T2/T1)(P1/P2)
V2 = (1 L)(2)(1/2)
V2 = (1 L)(2)(1/2)
V2 - 1 L
The volume does not change. Bummer.
Answer:
butane will be in gaseous state at 25 degrees and will be solid at -150 degrees.
Explanation:
As 25degrees is the room temperature so the state of butane at 25 degrees will be gaseous while the butane will freeze at -150degrees as it's beyond its melting point, it means it melts at -140degrees , it clearly shows that it exists in solid state before -140degrees.,
All chemical reactions follow the law of conservation of mass. This means that the number of atoms of a specie before the reaction must equal to the number of atoms of that specie after that reaction. The only change that occurs in chemical reactions is the breaking and formation of chemical bonds, due to which energy may be released or absorbed.
Answer:
Below
Explanation:
This is a single replacement/displacement reaction! This is the "formula" for single replacement : A + BC = AC + B
