what is mixture and types of mixture?

1. what is mixture and types of mixture?

Jawaban:

A mixture is composed of one or more pure substances in varying composition. There are two types of mixtures: heterogeneous and homogeneous. Heterogeneous mixtures have visually distinguishable components, while homogeneous mixtures appear uniform throughout.

2. what is the difference of homogeneus mixture and heterogeneus mixture!

homogenous = solution
separate using - distillation, evaporation to dryness, crystallization

heterogenous = suspension
separate using - filtration, separating funnel

3. There is a mixture of milk powder and sugar cubes. Davin mixes the mixture with water and filter it to separate the sugar cubes. Will it works ?

4. manakah ikatan ion yang paling kuat? (NaCl, NaBr, KCl, KF, KBr)

KCI klo gk salah atau nggak KBr

5. the music which is a mixture of calypso and jazz is named?

I searched for the answer on Google and the result that appeared is 

"Music of Barbados"

Not sure if that helps tho ;v

6. manakah ikatan ion yang paling kuat? (NaCl, NaBr, KCl, KF, KBr)

KF karena fluor memilik angka keelktronegativan 4 jd pengikat yg plg kuat diantara unsur halogen yang lain

jadikan jawaban terbaik ya

7. manakah ikatan ion yang paling kuat? (NaCl, NaBr, KCl, KF, KBr)

Ikatan Ion paling kuat dimiliki oleh KF

Penjelasan:

Ikatan Ionik atau Ikatan Ion atau Ikatan Elektrovalen adalah ikatan yang terbentuk akibat adanya tarik menarik  antara ion yang memiliki muatan yang berbeda.

Ikatan ionik terbentuk antara unsur yang bersifat logam dengan unsur yang bersifat non logam, dimana unsur logam akan mendonorkan elektron untuk unsur non logam yang membutuhkan tambahan elektron.

Ikatan ionik merupakan ikatan kimia yang tergolong kuat, karena adanya gaya tarik elektrostatis di dalamnya.

Senyawa ionik umumnya berbentuk padatan yang sifatnya keras namun rapuh dan mudah larut dalam air untuk terdisosiasi menjadi ion-ion penyusunnya dan juga tergolong sebagai Larutan Elektrolit Kuat.

Kekuatan ikatan ion dapat ditentukan berdasarkan pada perbedaan keelektronegatifan dari unsur penyusunnya.

Keelektronegatifan adalah suatu bilangan yang menggambarkan kecenderungan relatif dari suatu unsur dalam menarik elektron ke pihaknya dalam suatu ikatan kimia.

Berdasarkan pada uraian diatas, maka kita coba analisis kekuatan ikatan ionik pada senyawa ion yang terdapat pada soal berdasarkan pada perbedaan nilai keelektronegatifannya.

Nilai keelektronegatifan dapat dilihat pada tabel keelektronegatifan unsur-unsur.

Adapun nilai keelektronegatifan unsur berdasarkan tabel yaitu:

Na = 0,9

Cl = 3

Br = 2,8

K = 0,8

F = 4

maka:

Selisih keelektronegatifan dalam senyawa:

NaCl = 3 - 0,9 = 2,1

NaBr = 2,8 - 0,9 = 1,9

KCl = 3 - 0,8 = 2,2

KF = 4 - 0,8 = 3,2

KBr = 2,8 - 0,8 = 2

Jadi berdasarkan selisih keelektronegatifan maka dapat diurutkan sebagai berikut:

KF > KCl > NaCl > KBr > NaBr

Jadi ikatan ion paling kuat terdapat dalam senyawa KF

Demikian penjelasan terkait penentuan kekuatan Ikatan ion, semoga membantu.

Jawab:

0,15 litre

Penjelasan dengan langkah-langkah:

A litre of mixture consists of 0.25 litre of coconut water, 3/5 litre of plain water and the rest is honey. What is the percentage of honey in the mixture?

The percentage of honey can be counted by

1 litre - 0,25 litre of coconut water - 3/5 litre of plain water

= 1 - 0,25 - 0,6

= 0,15

So the honey is 0,15 litre.

17. A mixture of NaCl and KCl weighed 5.4892 g . The sample was dissolved in H2O and reacted with excess AgNO3 to form AgCl. This AgCl weighed 12.7052 g. Wht was the % NaCl in the original sample?

mass of NaCl and KCl : 5,4892 gram
mass of AgCl : 12,7052 gram
Concentration of NaCl in the sample : ... %

Answered

step 1
Make a reaction first. There are 2 type of the reaction.

1. A mixture of NaCl and KCl with H2O. H2O will decompose of the mixture to be NaCl + KCl

Reaction
NACl. KCl → NaCl + KCl

2. NaCl and KCl added AgNO3 leads to precipitate to the formation of AgCl

Reaction
NaCl + AgNO3 → AgCl + NaNO3

KCl + AgNO3 → AgCl + NaNO3

Step 2
Determine mole of AgCl

mole : mass / Mr

mole of AgCl : 12,7052 g / 143,5 g/mole
AgCl : 0,0885 moles

We has found out mole of AgCl. So, we can determine mole of Cl- in AgCl

Ag+ + Cl- → AgCl

mole of Cl- : (c. Cl-/c. AgCl) x moles of AgCl
Cl- : (1/1) x 0,0885 moles
: 0,0885 moles

step 3
Make a equation. There are 2 equation in the question. We know that NaCl and KCl dissociate completely in aqueous solution, so we can write the equation :
a : NaCl
b : KCl

The first equation
a + b : 0,0885

The second equation
If we want to make the second equation. We know the mixture contains NaCl and KCl. We have to convert moles of NaCl and KCl to gram

NaCl : a mole
Mr NaCl : 58,5 g / mole

KCl : b mole
Mr KCl : 74,5 g/mole

g NaCl : a mole x 58,5 g/mole
: 58,5a gram

g KCl : b mole x 74,5 g/mole
: 74,5b gram

So, the second equation is

58,5a + 74,5b : 5,4892

step 4
Determine value of a and b. By using the substitution method.

a + b : 0,0885
a : 0,0885 - b

58,5a + 74,5b : 5,4892
58,5(0,0885 - b) + 74,5b : 5,4892
5,1772 - 58,5b + 74,5b : 5,4892
16b : 5,4892 - 5,1772
b : 0,312 / 16
b : 0,0195

58,5a + 74,5b : 5,4892
58,5a + 74,5(0,0195) : 5,4892
58,5a + 1,4528 : 5,4892
a : 4,0364 / 58,5
a : 0,0690

step 5
Determine mass of NaCl. Substitution of value a so we can find out mass of NaCl

g NaCl : a mole x 58,5 g/mole
g NaCl : 0,0690 mole x 58,5 mole
: 4,0365 gram

step 6
Determine concentration of NaCl in the mixture.

% NaCl : (mass of NaCl / mass sample) x 100%
% NaCl : (4,0365 g / 5,4892 g) x 100%
: 73,53% (b/b)

So, the concentration of NaCl in the mixture is 73,53% (b/b)

18. A mixture containing 35% SiO2 and 0.55 g NaCl and an unknown amount at NH4CL, when the mixture is heated it mass was decreased to 1.75 g the mass at NH4CL in the mixture?

Suatu campuran yang mengandung 35% SiO₂ dan 0.55 g NaCl dan sejumlah yang tidak diketahui pada NH4CL. Ketika campuran dipanaskan massanya berkurang menjadi 1,75 g. Massa NH4CL dalam campuran adalah 0.85 gram.

Pembahasan

Silikon oksida, natrium klorida dan ammonium klorida merupakan senyawa yang terlarut dalam air. Kelarutan masing-masing senyawa tersebut berbeda-beda dalam air. Ketika berupa campuran diasumsikan merupakan campuran larutan dalam air. Adapun proses pemanasan dimaksudkan untuk menguapkan air saja, mengingat silikon oksida, garam NaCl, dan ammonium klorida memiliki titik didih yang sangat tinggi.

Diketahui :

Massa setelah pemanasan:
m SiO₂  = 0.35% massa total
m NaCl = 0.55 gram
m total = 1.75 gram

Ditanyakan :

m NH₄Cl = ?

Penyelesaian :

massa total = m NH₄Cl + m SiO₂ + m NaCl

1.75 gram =  m NH₄Cl + 0.35 (1.75) + 0.55

m NH₄Cl = 1.75 gram - 0.35 gram - 0.55 gram

m NH₄Cl = 0.85 gram.

Kesimpulan
Massa NH₄Cl dalam campuran adalah 0.85 gram.
