Answer 0,36 M
Hello!
The general chemical equation for the neutralization of an acid HA with NaOH is the following:
HA(aq) + NaOH(aq) → NaA(aq) + H₂O(l)
For determining the concentration of the acid solution, we can use the equation shown below:
So, the concentration of the Acid is 0,36 M

Explanation:
The owls would have to find an alternate food source and it would be harder for them to survive
Answer:
1072 torr
Explanation:
To answer this problem we can use <em>Gay-Lussac's law</em>, which states:
Now we convert the given temperatures into K:
- T₁ = 15°C ⇒ 15+273.16 = 288.16 K
- T₂ = 36°C ⇒ 36+273.16 = 309.16 K
We <u>input the data</u>:
- 1000 torr * 309.16 K = P₂ * 288.16 K
And <u>solve for P₂</u>:
<u>Answer: </u>The correct answer is Option B.
<u>Explanation:</u>
First law of thermodynamics states that the energy can neither be destroyed not be formed but it can only be transformed from one form to another.
Here, the internal energy of the system is being transformed to the heat energy and the work done by the system. The equation used to represent first law of thermodynamic is:
where,
represents the internal energy of the system.
Q = heat released or absorbed by the system.
w = work done by or on the system.
Hence, the correct answer is Option B.
