The new volume of the hydrogen gas at s.t.p., 
= 750 dm³
<h3>What is the molar volume of gas at
s.t.p?</h3>
The molar volume of a gas at s.t.p. is 22.4 dm³.
The change in volume gases at different temperatures and pressures are given by the general gas equation given below:
= 600 dm³
= 950mmHg
= 273 K
The new volume of the hydrogen gas at s.t.p., is calculated thus:
= (950 x 600 x 273)/(760 x 273) = 750 dm³
In conclusion, the volume of a gas changes with temperature and pressure changes.

Answer:
volume = 2128L
Explanation:
volume at stp = 22.4dm³ =22400L
CO2 = 12 + 2(16) = 44
4.20/44 = volume/22400L
0.095 = volume/22400L
volume = 0.095 x 22400
volume = 2128L
Hydrophobic. Since bilayer has hydrophobic tail as their core region, molecules can pass through the hydrophobic tail if they are also hydrophobic.
MNaHCO₃: 23+1+12+(48×3) = 84g
mCH₃COOH: 12+(1×3)+12+(16×2)+1 = 60g
.................
84g NaHCO₃ react with 60g CH₃COOH
83g NaHCO₃ react with...........
84g ----- 60g
83g ----- X
X = 59,29g CH₃COOH
We used 70g CH₃COOH, it' too much.
So, acetic acid is excess reagent, and sodium bicarbonate is limiting reagent.
_______________________________
B) Amount of CH3COOH is in excess.
