How does the activity series of metals tell which reactions will occur?

Chemistry

Helga [31]3 years ago

C. Metals higher in the series will replace metal ions in solution that

are lower in the series.

Explanation:

The activity series of metals shows the extent of reactivity of different metals.

On the activity series, the most reactive metals are located higher up on the able whereas the less reactive ones are found at the bottom of the series.

  • We can tell if single displacement reactions will occur by simply looking at the reactivity series.
  • Metals that are more reactive will displace the ones that are not very reactive that are positioned down the series. Such a reaction will occur.
  • Metals lower in the series cannot displace the ones on top because they are less reactive. Such a reaction will not occur.

When iron metal reacts with oxygen, the reaction can form Fe2O3. Write a balanced chemical equation for this reaction, and find
I am Lyosha [343]
<h3>Answer:</h3>

Balanced equation: 4Fe + 3O₂ → 2Fe₂O₃

Moles of oxygen gas = 9 moles

<h3>Explanation:</h3>

To answer the question;

  • We first write the balanced equation between iron metal and Oxygen
  • The balanced equation is given as;

4Fe + 3O₂ → 2Fe₂O₃

  • We are given 6 moles of Fe₂O₃

We are required to determine the number of moles of oxygen needed to form 6 moles of Fe₂O₃.

  • From the equation, 3 moles of oxygen gas reacts to produce 2 moles of Fe₂O₃
  • This means, the mole ratio of O₂ to Fe₂O₃ is 3 : 2

Therefore; Moles of O₂ = Moles of Fe₂O₃ × 3/2

Hence, moles of oxygen = 6 moles × 3/2

                                         = 9 moles

Thus, Moles of Oxygen needed is 9 moles

You are given a clear solution of KNO3. Using 3-4 sentences explain how you would determine if the solution is unsaturated,satur
Natasha2012 [34]
Without being given a temperature or amount of solute, it's not as easy to find the level of saturation. If there is excess of solvent in the beaker, the solution is unsaturated. In this case, the solution is clear so there is no indication of excess of solute or solvent. Therefore, the solution is saturated.
