what is the balanced net ionic equation for the reaction in acidic solution of fe2+ and kmno4 (fe2+ becomes ff3+ and MnO4 become
sveticcg [70]
The balanced half reactions are
4 Fe2+   ====> 4 Fe3+  + 4 e-

<span>MnO42- + 8 H+ +  4 e- ===>  Mn2+  + 4 H2O

The net ionic equation is
4 Fe2+ + </span>MnO42- + 8 H+ ===> 4 Fe3+  + Mn2+  + 4 H2O<span />

What is the Bronsted-Lowry definition of an acid?
victus00 [196]

The correct answer is that a compound that donates protons.  

On the basis of Bronsted-Lowry concept, a compound which accepts proton is considered as a base and the compound which donates protons is considered to be an acid. The strong acids and bases get ionized completely in aqueous solution, while the weak acids and weak bases get ionize partially.  

The conjugate base is illustrated as the species that is produced after the loss of proton of acid, while the conjugate acid refers to the species that is produced after the gain of protons.  

Thus, the Bronsted-Lowry definition of an acid is a compound that donates protons.

The heat of a reaction may be found with the equation q=mcΔT.
sweet-ann [11.9K]

Answer:

B) -1551 kJ  

Explanation:

There are two heat flows in this question.

Heat released by engine + heat absorbed by water = 0

                   q₁                    +                      q₂                = 0

                   q₁                    +                   mCΔT            = 0

Data:

  m = 2.51 kg

  C = 3.41 J°C⁻¹g⁻¹

T_i =   23.8 °C

T_f =205     °C  

Calculations:

(a) ΔT

ΔT = 205 °C - 23.8 °C = 181.2 °C

(b) q₂

q₂ = mCΔT = 2510 g × 3.41 J·°C⁻¹g⁻¹ × 181.2 °C = 1.551× 10⁶ J = 1551 kJ

(c) q₁

q₁ + 1551 kJ = 0

q₁ = -1551 kJ
