2. Magnesium Sulfate could be made in the laboratory by neutralising a base, Magnesium Oxide, with an acid. What is the acid and write a balanced equation for the reaction.


The acid is sulphuric acid (H2SO4)

The reaction is:
[tex] MgO + H_2SO_4 => MgSO_4 + H_2O [/tex]H₂SO₄ (sulfuric acid)

Balanced equation of the reaction

[tex]MgO_{(s)} + H_2SO_4_{(aq)} \rightarrow MgSO_4_{(aq)} + H_2O_{(l)} [/tex]

6. The correct statement for pulmonary circulation is …. a. oxygen and carbon dioxide is exchanged inside the lungs b. oxygen and carbon dioxide is exchanged in the body cells c. blood rich in carbon dioxide returns to the heart in the right atrium d. blood rich in carbon dioxide goes out from the left ventricle to the whole body


Jawaban:

Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.

The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.

From there, the blood flows through the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart.

The right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA).

From there, the blood flows through the right and left pulmonary arteries into the lungs.

In the lungs, oxygen is put into the blood and carbon dioxide is taken out of the blood during the process of breathing. After the blood gets oxygen in the lungs, it is called oxygen-rich blood.

Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins.

Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.

The left ventricle (LV) pumps the oxygen-rich blood through the aortic valve (AoV) into the aorta (Ao), the main artery that takes oxygen-rich blood out to the rest of the body.

9. The production budget is the first budget prepared in the master budget. true false


Jawaban:

True

Penjelasan:

The first budget a company prepares in a master budget is the production budget. One disadvantage of a self-imposed budget is that budget estimates prepared by front-line managers are often less accurate and reliable than estimates prepared by top managers.

11. Manganese(III) fluoride, MnF3, can be prepared by the following reaction: 2MnI2(s) + 13F2(g) ? 2MnF3(s) + 4IF5(l) If the percentage yield of MnF3 is always approximately 56%, how many grams of MnF3 can be expected if 10.0 grams of each reactant is used in an experiment?


Kelas: X

Mata pelajaran: Kimia

Materi: Soikiometri
Kata Kunci: Pereaksi pembatas


Jawaban pendek:

 

Manganese(III) fluoride, MnF3, can be prepared by the following reaction:

 

2 MnI2(s) + 13 F2(g) -> 2 MnF3(s) + 4IF5(l)

 

If the percentage yield of MnF3 is always approximately 56%, MnF3 can be expected if 10.0 grams of each reactant is used in an experiment is 2 gram

 

Jawaban panjang:

 

Dalam persoalan ini, akan direaksikan 10 gram dari mangan (II) iodida (MnI2) dengan 10 gram gas florida (F2), dalam reaksi

 

2 MnI2 (s) + 13 F2 (g) -> 2 MnF3 (s) + 4 IF5 (l)

 

Karena itu, pertama kita harus menghitung jumlah molekul dari mangan (II) iodida (MnI2) dan gas florida (F2), bereaksi dengan menghitung massa molekul (Mr) keduanya.

 

Bila nomor massa (Ar):

 

Mn = 55, I = 127, F = 19,

 

Maka massa molekul (Mr):

 

MnI2 = 55 + 2 x 127 = 309

F2 = 2 x 19 = 38

MnF3 = 55 + 3 x 19 = 112

IF5 = 127 + 5 x 19 = 222

 

Sehingga jumlah molekul bereaksi adalah:

 

n MnI2 = 10 / 309 = 0,032 mol

n F2 = 10 / 38 = 0,26 mol

 

Lalu kita menentikan Reaktan pembatas dalam reaksi ini:

 

rasio MnI2 = mol MnI2 / koefisien MnI2

                  = 0,032 / 2

                  = 0,016

 

rasio F2 = mol MgIF22 / koefisien F2

                  = 0,26 / 13

                  = 0,02

 

Karena rasio MgI2 lebih kecil maka MgI2 adalah pereaksi pembatas dan akan habis terlebih dahulu.

 

Sehingga 0,032 mol MnI2 akan bereaksi habis dengan F2 menghasilkan MnF3 sejumlah:

 

jumlah MnF3 hasil = koefisien MnF3 / koefisien MgI2 x n MgI2

                             = 2/2 x 0,032

                             = 0,032 mol

 

Massa dari MnF3 teoritis yang dihasilkan adalah:

 

Massa MnF3 = n MnF3 x Mr MnF3

                      = 0,032 x 112

                      = 3,6 gram

 

Namun, MnF3 yang dihasilkan hanya 56% saja, sehingga massa MnF3 sebenarnya yang dihasilkan adalah:

 

Massa MnF2 dihasilkan = 56% x 3,6

                                       = 2 gram
