Can you check if this is correct please:
Reactivity order for these metals (top being most reactive):
- Magnesium (I'm not sure if Magnesium or Manganese should be at the top)
- Manganese
- Zinc
- Copper
Reactivity order for these acids (top being most reactive):
- Sulfuric acid
- Hydrochloric acid
- Ethanoic acid
- Citric acid
Thank you :)
To determine the reactivity order of metals and acids, we need to consider their tendency to undergo chemical reactions.
For metals, reactivity generally increases as we move down a group in the periodic table and decreases as we move across a period.
To determine the reactivity order of metals, we can use a mnemonic: "Please Stop Calling Me Cute Zebra." The first letter of each word corresponds to the first letter of the metal in question.
Let's apply this mnemonic to the given metals:
- Magnesium (Mg)
- Manganese (Mn)
- Zinc (Zn)
- Copper (Cu)
Using the mnemonic, we see that zinc comes before copper, so the correct reactivity order for these metals (from most reactive to least reactive) is:
1. Magnesium
2. Zinc
3. Manganese
4. Copper
For acids, reactivity is determined by their tendency to donate protons (H+ ions) in a chemical reaction. Strong acids tend to fully dissociate in water, while weak acids only partially dissociate.
Comparing the given acids, we can arrange them in order of increasing reactivity based on their strength as follows:
1. Citric acid (a weak acid)
2. Ethanoic acid (also known as acetic acid, a weak acid)
3. Hydrochloric acid (a strong acid)
4. Sulfuric acid (a strong acid)
So, the correct reactivity order for these acids (from least reactive to most reactive) is:
1. Citric acid
2. Ethanoic acid
3. Hydrochloric acid
4. Sulfuric acid
Remember that reactivity orders can vary depending on the specific reaction and conditions.
