Answer:
Number of delocalized electrons
Explanation:
Magnesium has more delocalized electrons compared to sodium and this accounts for the higher melting point.
- When magnesium atoms comes together to form a metallic bonds, they have more network of delocalized electrons.
- There is more pull for the localized electrons due to the nuclear charge on the nucleus.
- This strong intermolecular metallic bond increases the melting point of magnesium.
Hope that helps, pls double check tho :)
K2 SO4 = 2[K+] + [SO4 2-]
Which means that every mol of K2SO4 gives 3 moles of ions.
Then 1.25 mol of K2SO4 gives 3*1.25 = 3.75 moles of ions.
Answer: 3.75
Answer:
Use bags that are not of plastic and that we can reuse.
Explanation:
To reduce the number of petroleum, people should use everyday things that do not have plastic in their composition. For example, drink water from a flask made of iron, take your mug to the coffee store or use cloth bags. These elements are not disposable, and we can use them multiple times, which leads to a reduction in the consumption of plastic products and the amount of petroleum needed for their production.
