The theoretical yield (in kilograms) of water produced from this reaction : 0.285 kg

<h3>Further explanation</h3>

Reaction

2C₁₂H₂₄O₁₁ + 25O₂ → 24CO₂ + 24H₂O

mass of C₁₂H₂₄O₁₁ - isomaltitol = 454 g

mol C₁₂H₂₄O₁₁(MW=344.31 g/mol) :

\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{454}{344.31 g/mol}\\\\mol=1.319

mol H₂O based on C₁₂H₂₄O₁₁ as limiting reactant(O₂-oxygen as an excess)

From the equation above, mol ratio of C₁₂H₂₄O₁₁  : H₂O = 2 : 24, so mol H₂O:

\tt mol~H_2O=\dfrac{24}{2}\times 1.319=15.828

then mass H₂O (MW=18 g/mol) :

\tt mass=mol\times MW\\\\mass=15.828\times 18=284.904~g=0.285~kg

What happens to the ionizing rate if the steps of ionizing polyprotic acid increases?
Tanzania [10]

Answer:

<h3>An acid that contains more than one ionizable proton is a polyprotic acid. The protons of these acids ionize in steps. The differences in the acid ionization constants for the successive ionizations of the protons in a polyprotic acid usually vary by roughly five orders of magnitude.</h3>

Answer:

Difference in the potential energy of the reactants and products

Explanation:

 

The products have a lower potential energy than the reactants, and the sign of ΔH is negative. In an endothermic reaction, energy is absorbed. The products have a higher potential energy than the reactants, and the sign of ΔH is positive.

Given the reaction that occurs in an electrochemical cell:
KatRina [158]

Answer:

c) +2 to 0

Explanation:

SO4 has a charge of -2, so the Cu attached to that has to be a +2 since the polyatomic molecule has no overall charge

Cu(s) is a solid metal and they have no charge, therefore it is zero

Copper undergoes Oxidation (gain of electrons)
