Answer:
Option (a) is the correct answer.
Explanation:
The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.
Therefore, we can conclude that option (a) is the correct answer.
Answer and Explanation:
The reaction is in the gas phase, so the equilibrium constant is expressed in terms of the partial pressures (P) of the products and reactants, as follows:

We have the following data:
P(SO₃) = 2.6 atm
P(O₂) = 0.43 atm
We need Kp for this reaction. We can assume that in Appendix 4 we found that Kp = 7 x 10²⁴.
Then, we introduce the data in the equilibrium constant expression to calculate the partial pressure f SO₂ (PSO₂), as follows:

Therefore, the partial pressure of SO₂ is 1.5 x 10⁻¹² atm (for the given Kp).
167 mL
P1V1 = P2V2
P1 = .8 atm
V1 = 250 mL
P2 = 1.2 atm
Solve for V2 —> V2 = P1V1/P2
V2 = (0.8 atm)(250 mL) / (1.2 atm) = 167 mL
Answer:
C.electron po yung sagot
Explanation:
because electron has a 0.0005 mass
and -1 charge.
thanks me later
