Answer:
300K.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 300L
Initial temperature (T1) = 200K
Final volume (V2) = 450L
Final temperature (T2) =..?
Since the pressure is constant, the gas is obeying Charles' law.
Using the Charles' law equation, we can obtain the new temperature of the gas as follow:
V1/T1 = V2/T2
300/200 = 450/T2
Cross multiply to express in linear form
300 x T2 = 200 x 450
Divide both side by 300
T2 = (200 x 450)/ 300
T2 = 300K
Therefore, the new temperature of the gas is 300K.

6.023 x 10^23 . Common salt . Total of 12.046 x 10^23 atoms
Answer:
Explanation:
I₂ + 2 e = 2I⁻
I₂ converts itself into I⁻ by accepting electron . In this process it increases the oxidation number of element from which it takes electron . Hence it is an oxidizing agent .
Similarly O₂ is also an oxidizing agent .
O₂ + 4e = 2O⁻²
Al is a reducing agent .
Al = Al⁺³ + 3 e
Al gives 3 electrons to other element whose oxidation number is reduced . Hence it is reducing agent .
Similarly Cr is also a reducing agent .
Cr = Cr⁺³ + 3 e .
Plug in what you know
-Heat (q) is 2520
-Delta T (change in temperature) is 70-10 which is 60
-Mass (M) is 10kg
-specific heat (c) is unknown.
2520 = (10)C(60)
Use algebra to solve for C.
Multiply C by 60 and 10.
2520 = 600C
Divide both sides by 600 to get C by itself.
C = 4.2 J/g
