Answer:
Explanation:
The reaction between hydrogen and oxygen to yield water vapor has ΔH∘=− 484kJ. How much pV work is done, and what is the value of ΔE in kilojoules for the reaction of 0.50 mol of H2 with 0.25 mol of O2 at atmospheric pressure if the volume change is −5.6 L?
2H2(g)+O2(g)⟶2H2O(g)ΔH∘=− 484kJ

Answer:
3048 cm
Explanation:
As we know, there are 30.48 cm in one foot THUS in 1×10^2 feet (= 100 feet) there are centimeters equal to 30.48×100 = 3048 cm
Answer:
HCl (l) + H₂O(l) → H₃O⁺(aq) + Cl⁻(aq)
Explanation:
Arrhenius' acid-base concept indicates that a substance will be an acid when it produces in water hydrogen H⁺ ions or hydronium H₃O⁺ ions.
In turn, the substance will be base if when reacting in water it produces hydroxide ions (OH⁻)
The HCl reacts in water in order to produce hydronium ions and chlorides
