Carbon dioxide is the answer
Potassium belongs to the Alkali metals group
The maximum weight of liquefied petroleum gas that can be stored in one indoor area is 200 pounds.
<h3>
What is liquefied petroleum gas?</h3>
Liquefied petroleum gas (LPG), also called LP gas, any of several liquid mixtures of the volatile hydrocarbons propene, propane, butene, and butane.
<h3>How is liquefied petroleum gas stored?</h3>
Liquefied petroleum gas (LPG) is stored in pressure vessels. As such, it is almost always stored in its liquid form.
Thus, the maximum weight of liquefied petroleum gas that can be stored in one indoor area is 200 pounds.

Answer:
This question is incomplete, the complete question is; assuming that the solution has a specific heat of 4.18 J/g°C
The answer is 381.67 J/g
Explanation:
Enthalpy change denoted by ΔH can be calculated using the formula;
ΔH = m × c × ΔT
Where; m= mass of reactants
c= specific heat
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 32.76 - 19.3
ΔT = 13.46 °C
mass of reactants= 85.6 + 14.8 = 100.4g, c = 4.18J/g°C
Hence; ΔH = m × c × ΔT
ΔH = 100.4 × 4.18 × 13.46
ΔH = 5648.78J
Enthalpy change per gram of potassium hydroxide dissolved in the water is;
ΔH = 5648.78/14.8
ΔH = 381.67 J/g
Answer : The limiting reactant is, carbon (C)
Explanation : Given,
Moles of = 2 moles
Moles of C = 5 moles
Now we have to calculate the limiting and excess reagent.
The given balanced chemical reaction is:
From the balanced reaction we conclude that
As, 3 mole of react with 1 mole of
So, 5 moles of react with moles of
From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.
Thus, the limiting reactant is, carbon (C)
