Children of blood and bone essay

Do you think everyone should get treated equally?
I asked that question because In the book children of blood and bone by Tomi Adeyemi, some character get treated right and some get treated wrong, there are also multiple pov * points of views* to show how the people get treated. some memorable ideas are learned through the relationships between Amari and Zelie meet when Zelie and inan meet, and when tzain and Amari meet. 

the first memorable idea is when Amari and Zelie met because  Amari was a princess and Zelie was someone who didn't like the royal family.  Amari and Zelie met in the little alley they did know each other. Zelie had her suspicions about Amari. when Zelie found out Amari was the princess (next queen of orisha) she was furious.  after the start, Zelie started to get used to Amari's company. Amari started to think that Zelie and she were friends but Zelie wouldn't agree. she said to tzain (pronounced Zane)
 “Well, even if I did, I can’t. Her father ordered the Raid. Her brother burned down our village. What makes you think she’s any different?”. 

the second memorable idea is when tzain and Amari meet because from the start the writer made it look like he liked Amari because he gave Amari his jacket, etc *they liked each other*. *, in my opinion,* I think tzain and Amari would be an adorable couple. at points in the story, they got very close and at others, they were just stuck alone waiting for help. they had a good relationship that wasn't really talked about much. quote from the website "During their journey the two have formed a close romantic relationship with each other".  Amari and the trains relationship were not talked about much because they were mostly running from inan.

the third memorable *not really I just want to state* is when tzain and inan meet because they didn't have a good relationship. inan at the start was not the best. they author stated that Amari and inan had a good relationship but when Amari runs away tzain gets told to get her and kill everyone who with her. when tzain found out about inan he heard storeys and see Amaris back where the scar was.  personally, I don't think tzain like what happened because he liked Amari so much that they explained it a lot.

the fourth idea is when inan and Zelie meet because it shows when in real life how fake people use you basically.  inan was the character who uses Zelie because he wanted to make his dad happy.  Zelie and inan did have a type of love that wasn't the best for both of them. tzain knew that Zelie was gonna get hurt and warned her and she did not listen to him. Zelie took her anger out on tzain even tho he was right all along.

Now we have looked at these points I personally think that I have finished the book I have learnt a lot from what has happened in the book. I learnt the most from Zelie and Inans relationship because she realizes that he is fake and that she needed to say bye to him.

Then theirs change. *pun not intended*

Aim- To turn copper into silver and gold

Equipment-

  • Two small beakers (50mL and 250 mL)
  • bunsen burner
  • tweezers
  • Zinc sulfate 100g
  • Zinc metal, grandular 100g
  • glass stir rod
  • tap water
  • Copper pennies, well cleaned 


Method-

  1. fill the small 50 mL beaker 3/4 full tap water. this is your rising beaker. set aside
  2. dissolve 30 grams of zinc sulfate in 100mL of water in the 250mL beaker. a little heat from setting on the bunsen burner will hasten this dissolve.
  3. place mossy zinc pieces in the beaker with the zinc sulfate solution, enough pieces to almost cover beaker bottom 
  4. using tweezers, place two or three cleaned up pennies in step three beaker making sure pennies touch the grandular zinc pieces and are not touching each other 
  5. bring the solution to a low boil for about 10 minutes. your pennies will slowly turn a silver colour.
  6. using tweezers, carefully remove the pennies from the solution, rinse and cool them in small wash beaker then dry them on a paper towel.
  7. Boom! magically  you have  you have coloured pennies (coins)

Results-








Discussion-
a coin *a ten cent* is dipped into zinc sulfate and in contact with the zinc, the coin starts its change. the coin is plated with zinc and appears silver to the human eye. the coin that looks silver because of the zinc is placed above the bunsen burner flame for about half a minute (30 seconds) and then it should appear gold to the eye. the zinc and copper form an alloy of brass. the coin now appears gold.

Evaluation-
if I were to this whole experiment again I would definitely not use the actual metal I would use the zinc powder. when we use the zinc metal it takes way too long to actually put the plating onto the coin. but when we added the zinc powder it went 10x faster than it was.

Pretty chemicals!!!!

Making salt (crystals)
Aim: to produce copper sulfate by reacting copper oxide with an acid.

Equipment: Copper oxide power, dilute (0.5 mol ⁻¹) sulfuric acid, 50mL measuring cylinder, two 100mL beakers, Busen burner, tripod (not the one for cameras), gauze mat, funnel, filter paper, thermometer, spatula, evaporating basin, stirring rod.

methods: 
1. add 20mL of sulfuric acid to a 100mL beaker. heat the acid until it reaches  70ᵒc.   turn off your bunsen burner.

2. once heated, use a spatula to add pea-sized portions of copper oxide to the beaker. stir the mixture for 30 seconds.

3. repeat step 2 until no more will dissolve

4. fold the filter paper and place it in the funnel. place the filter funnel into the second beaker.

5.make sure the beaker is cool enough to hold at the top. the contents should still be hot. you may need your teacher to complete this step.

6.gently swirl the contents of the beaker to mix, and then pour into filter paper in the funnel. allow filtering through.

7.rinse the beaker you used to heat the mixture previously and place it back on top of your tripod filled with 50-60mL of water.

8. place the evaporating basin on top of the beaker and carefully pour some of the solutions from the beaker into the evaporating basin.

9. gently heat the beaker until the solution in the evaporating basin has reduced by half.

10. leave the evaporating basin to cool. once cool, move the evaporating basin to a warm place where it will not be disturbed  (i.e a window sill) and observe over the next few days. blue copper sulfate crystals should form.

Observations-
- when u add the powder the solution turns black
- when u keep burning the solution it starts turning into a blue colour.
-when it gets filtered it changes to a light(brighter blue)
-as the water started to burn the solution it starts to crystallise on the sides
- the solution at the ends is fully crystallized.

conclusion-
the copper sulfate and copper oxide mixed together. then magically  the chemicals turn into a crystal.
