Answer:
2487.51.
Explanation:
As per Boyle's law temperature remaining constant the volume of an ideal gas is inversely proportional to its pressure.
pV= k
therefore, p1V1 = p2V2
here V1 = 25.3, p2 = 8.04mm Hg
pressure p1 = 790.5 mm Hg
this means that
25.3×790.5 = 8.04V2
⇒V2= 2487.51
Hence, the required volume is, 2487.51.
Answer:
Critical coordinate drivers incorporate living space alter, climate alter, obtrusive species, over exploitation, and contamination. Most of the coordinate drivers of corruption in biological systems and biodiversity right now stay steady or are developing in escalated in most biological systems.

Answer:
1).....for the specific heat capacity(c) of water is 4200kg/J°C..
....guven mass(m)=320g(0.32kg)
...change in temperature(ΔT) =35°C
from the formula
Q=mcΔT
Q=0.32Kg x 4200kg/J°C x 35°C
Q=47,040Joules
The question is incomplete, here is the complete question:
What volume (mL) of the partially neutralized stomach acid having concentration 2 M was neutralized by 0.1 M NaOH during the titration? (portion of 25.00 mL NaOH sample was used; this was the HCl remaining after the antacid tablet did it's job)
<u>Answer:</u> The volume of HCl neutralized is 1.25 mL
<u>Explanation:</u>
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of stomach acid which is HCl
are the n-factor, molarity and volume of base which is NaOH.
We are given:
Putting values in above equation, we get:
Hence, the volume of HCl neutralized is 1.25 mL
