Answer:
The final pressure will double i.e it will be twice the initial pressure
Explanation:
T1 = T
T2 = 2T ( twice the original T)
P1 = P
P2 =?
Since the volume is constant,
P1/ T1 = P2 /T2
P/ T = P2 / 2T
Cross multiply
T x P2 = 2T x P
Divide both side by T
P2 = (2T x P) / T
P2 = 2P
Therefore, the final pressure will double i.e it will be twice the initial pressure
Answer:
A. 3A + 2D → 2C + F
B. B is an intermediate
C. rate = k[A]³
D. rate = k`[D]²
Explanation:
Part A
The overall reaction is the sum of all the elementary steps:
3A→B+C
+
B+2D→C+F
<u> </u>
3A + 2D → 2C + F
Part B
A reaction intermediate is one that participates in the elementary steps, but it is not a product. Notice B is produced in the first step and consumed in the second, therefore it is an intermediate species.
Part C
The rate law is the product of the reaction constant, k, times the concentration of the reactants raised to the power of their coefficients in the balanced reaction assuming that it is the slow step in the reaction mechanism.
rate = k[A]³
Part D
Again as in part C:
rate = k [D]² ( B is not included since as we saw it is an intermediate )
Answer:
76 mmHg
Explanation:
The partial pressure of a gas in an ideal gas mixture is the pressure that this gas would exercise if it was alone in the same temperature of the gas mixture.
For the Raoult's law, we can determinate the partial pressure of a gas(Pa) knowing the total pressure (P) and its molar fraction(Xa):
Pa = XaP, so for the oxygen :
Pa = 0.10x760
Pa = 76 mmHg
Answer:
False
Explanation:
Heres what its made of:
The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.
Answer:
Atomic Mass
Explanation:
it is also sometimes below the symbol of the element :)
