Explain in terms of structure and bonding why nickel has a high melting point​

Answers

Answer 1

Answer:

contains positive (metal) ions or protons or nuclei and delocalised / mobile / free / sea of electrons

strong attraction between them or strong metallic bonds

Answer 2

Nickel is a metal and therefore it contains positive ions, called protons, which are surrounded by a sea of delocalized electrons, which are negative ions. There is a strong force of attraction between these positive and negative ions, and this requires a large amount of energy to break.

What is Nickel

Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile. Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer forms on the surface and prevents further corrosion (passivation). Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel-iron meteorites that were not exposed to oxygen when outside Earth's atmosphere.

Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron-nickel mixture is thought to compose Earth's outer and inner cores.

The question is confusing no offense

It is given that, 2 g of suppositories is needed to prepare. The part of water in the whole of the given composition is 10. The 10% of 2 g is 0.2 g. Therefore, 0.2 g of water that is 0.2 ml of water is needed for the given recipe.

What is percentage composition?

The percentage composition of a compound or sample is the percentage fraction of each of its constituent components. For example, if we consider the compound  magnesium sulphate pentahydrate, we can say the percentage composition for each component magnesium sulphate and water.

The density of water is 1 g/ml. Hence, 1 gm of water is equivalent to the volume of  1 ml for water. Given that, for making 2 g of the suppositories, 10 parts of water is required. Take this as the percentage composition of water in 2 g.

Hence, 10% of water is needed.  

10 % of  2  = 10/100× 2 = 0.2 g

Therefore, 0.2 g or 0.2 ml of water is required.

It's hard for me to live my everyday life like I used to, and that's because I just can't bear the emotional pain of getting scolded or slightly told something negative about myself or what I'm doing. It gets hard to breathe sometimes and I start breathing rapidly and can't calm down. I don't think it's anxiety but It's pretty close.. people on the internet make it hard to keep my thoughts clear because I yell at myself in my head that I'm just faking it like others are on the internet and beat myself up, even more, when my heart starts hurting and it gets hard to breathe. It's also hard to feel any other emotions for long, like feeling happy, or thankful. I just end up thinking "There's a person out there more worthy of this than me, we should just switch places I know I deserve any hardships in life", I've told my mom recently and it went away for just a little under a week.
