Select the single best answer. Consider the following half-reactions: MnO4−(aq) + 8H+(aq) + 5e−→ Mn2+(aq) + 4H2O(l) NO3−(aq) + 4

H+(aq) + 3e− → NO(g) + 2H2O(l) Will NO3− oxidize Mn2+ to MnO4− under standard-state conditions? NO3− ions will oxidize Mn2+ to MnO4− under standard state conditions. NO3− ions will not oxidize Mn2+ to MnO4− under standard state conditions.

Answer:

NO3− ions will not oxidize Mn2+ to MnO4− under standard state conditions.

Explanation:

The reduction potential of NO3^- is +0.96V while the reduction potential of MnO4^- is +1.51V. Hence looking at the reduction potential values stated above, NO3^- will not oxidize Mn^2+ to MnO4^-.

The MnO4^- having a greater reduction potential will be reduced to Mn^2+ while NO3^- will be oxidized to NO.

If the equation CO(g) + 2H2(g) →← → ← CH3OH(g) + energy is for a system at equilibrium, increasing the temperature will cause __
Eddi Din [679]

Answer:

[CH₃OH] to decrease and [CO] to increase.

Explanation:

  • Since the energy appears as a product. So, the system is exothermic that releases heat.
  • Increasing the temperature of the system will cause the system to be shifted to the left side to attain the equilibrium again.
  • So, the right answer is:

<em>[CH₃OH] to decrease and [CO] to increase.</em>

When salt is added to water, the entropy, S,
Dovator [93]

Answer:

C. number of particles

Explanation:

Entropy is the measure of disorderliness of a system. Remember that when you dissolve salt in water, you increase the number of particles in the solution. The greater the number of particles in solution, the greater the entropy of the  solution system.

Hence dissolution of a salt in water increases the entropy by increasing the number of particles in solution leading to the inequality; Ssolution > Swater + Ssalt.

which of the following would a chemist be most likely to study? a. a leaf floating on water c. a leaf being blown by the wind b.
Salsk061 [2.6K]
I think the correct answer from the choices listed above is option B. It would be a leaf changing color in autumn <span>would a chemist be most likely to study. A chemist should be more interested in processes that chemical reactions are most likely to occur and changes in color can be one of the indications of such reactions.</span>

A solution is prepared by dissolving 4.40 g of KSCN in enough water to make 200 mL of solution. What is the concentration of the
attashe74 [19]
First find the number of moles of KSCN is in 4.40g of KSCN 1. Number of moles = mass given (4.40g) / molecular weight(MW) (KSCN) - to calculate MW, look for each element in the periodic table and add their atomic weight 2. Convert 200mL to liters 3. Concentration = number of moles/ volume in liters from (#2)
