Consider this reaction: h2s + hno3 s + no + h2o reduction half-reaction: n+5 + 3e- n+2 oxidation half-reaction: s-2 s + 2e- after balancing the chemical equation, what are the coefficients for these compounds?

After balancing the chemical equation, what are the coefficients for these compounds?

H2S      

⇒ 3

HNO3    

⇒ 2

Works for EDG

Coefficient of = 3

Coefficient of = 2

Coefficient of = 2

Coefficient of = 4

Coefficient of = 3

Explanation:

Overall reaction

Reduction half-reaction:

...(1)

Oxidation half-reaction:

...(2)

2×(1) + 3×(2)

Coefficient of = 3

Coefficient of = 2

Coefficient of = 2

Coefficient of = 4

Coefficient of = 3

yes it is balanced

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
