Answer:
V₂ = 15.00 atm
Explanation:
Given data:
Initial pressure = 5.00 atm
Initial volume = 3.00 L
Final pressure = 760 mmHg ( 760/760 = 1 atm)
Final volume = ?
Solution:
P₁V₁ = P₂V₂
V₂ = P₁V₁ / P₂
V₂ = 5.00 atm × 3.00 L / 1 atm
V₂ = 15.00 atm
Answer:
2KClO3 》》2KCl +3O2
C+ O2》》CO2
number of C moles
Required O2 moles (According to the mole ratio )
Relevant to the first equation, find the moles the KClO3, which is used to produce that amount of O2 moles
Now you can find the mass of KClO3
I mentioned the useful steps which can guide you to get the answer.

Answer:
Explanation:
Hello!
In this case, since it is possible to assume that the heat released by the reaction is absorbed by the water in the calorimeter we can write:
Now, since the reaction between silver nitrate and hydrochloric acid is:
We can see there is a reacting 1:1 mole ratio, thus, the reacting moles are computed via the molarity of the solutions:
Finally, the enthalpy of reaction is:
And in kJ:
Best regards!
To some point it may get hotter because your getting closer to the sun as well <span>sunlight gets converted into heat mainly at the Earth's surface</span>
