There are four choices to choose from in regards with this problem and fortunately I know the answer to the said question:
Listed below are the choices:
a.) 6.0 L of H2(g) at STP
b.) 12.0 L of CO2(g) at STP
c.) 18.0 L of HCI(g) at STP
d.) 24.0 L of O2(g) at STP
The correct answer is b. 12.0 L of CO2 (g) at STP
Note:
STP or (Standard Temperature and Pressure) - most commonly used when performing calculations on gases (e.g. gas density)
Volume of carbon dioxide absorbed = 33.6 L ≈ 34 L
Explanation:
We have the following chemical reaction:
CO₂ (g) + 2 LiOH (s) → Li₂CO₃ (s) + H₂O (l)
Now we devise the following reasoning:
if 1 mole of carbon dioxide reacts with 2 moles of lithium hydroxide
then X moles of carbon dioxide reacts with 3 moles of lithium hydroxide
X = (1 × 3) / 2 = 3/2 moles of carbon dioxide
And we calculate the volume of carbon dioxide using the following formula:
number of moles = volume / 22.4
volume = number of moles × 22.4
note: units for 22.4 are "L / mole"
volume of carbon dioxide = (3/2) × 22.4 = 33.6 L ≈ 34 L

A mole of sodium chloride has mass 58.44 grams. You get that from adding the molar masses of sodium and chlorine, which are listed on the periodic table.
<span>58.44 g/mol * 4.40 mol = 257.1 or ≈ 257 grams with 3 significant figures</span>
I’m pretty sure it’s D because energy measures the kinetic, thermal, electrical, chemical, nuclear and other forms.
