Answer:
+ 0.617 v
Explanation:
Sn2+ (aq) + 2Fe3+ (aq) → 2Fe2+ (aq) + Sn4+ (aq)
half-life
Sn²⁺ → Sn⁴⁺ + 2e⁻ oxidation E ox = -0.154 v
2 Fe³⁺ + 2e⁻ → 2 Fe ²⁺ reduction E red = + 0.771 v
E° cell = E°red + E° ox = +0.77 v + (-0.154 v) = + 0.617 v
Answer:
The Haber Process combines nitrogen from the air with hydrogen derived mainly from natural gas (methane) into ammonia. The reaction is reversible and the production of ammonia is exothermic. The catalyst is actually slightly more complicated than pure iron.
Explanation:
For this reaction, the mass of carbon dioxide and glucose involved are the product of thier molar mass and the number of moles of each compound involved in the reaction.
carbon dioxide: 6 x (12 + 2 x 16) = 264
glucose : 1 x (6 x 12 + 12 + 6 x 16) = 180
Divide their masses to get the equivalent weights. The answer is 22/15 or 11/7.5.
Divide by 1000
145÷1000=0.145

Simple molecules have no overall charge, or charged particles that can separate, so simple molecular substances cannot conduct electricity, even when liquid or dissolved in water.
