5. The complete combustion of copper (I) sulphide is according to the following equation:2Cu2S(s) + 302(g) →2Cu2O(s) +2502(g)If the mass of Cu2S in the mixture is 14.0 g. calculate(a) the number of mole of oxygen gas reacted.
Answer with explanation :
The reaction of complete combustion of Copper (I) Sulphide
2Cu₂S (s) + 3O₂ (g) → 2Cu₂O (s) +2SO₂ (g)
The mass of Cu₂S that we got equals to 14.0 g
⟡ ⟡ ⟡
In order to find moles of O₂ gas that reacts with Cu₂S, we must know moles of Cu₂S solid first.
Moles of Cu₂S = [tex]\frac{m}{Mr}[/tex]
Where,
Mass (m) of Cu₂S = 14.0 g
Molecular mass (Mr) of Cu₂S = 159.16 g/mol
So then,
Moles of Cu₂S = [tex]\frac{14.0 \ g}{159.16 \ g/mol}[/tex] = 0.0879 moles
⟡ ⟡ ⟡
And to get the required number of moles, use the ratio of coefficient in the reaction,
2Cu₂S (s) + 3O₂ (g) → 2Cu₂O (s) +2SO₂ (g)
⇒ Cu₂S : O₂ : Cu₂O : SO₂
⇒ 2 : 3 : 2 : 2
Moles of O₂ = [tex]\frac{Coeffiecient \ of \ O_{2}}{Coeffiecient \ of \ Cu_{2}S} \times moles \ of \ Cu_{2}S}[/tex]
Moles of O₂ = [tex]\frac{3}{2} \times 0.0879 moles}[/tex]
Moles of O₂ = [tex]1.5 \times 0.0879 \ moles[/tex]
Moles of O₂ = [tex]0.13185 \ moles[/tex]
Moles of O₂ ≈ [tex]Approximately\ 0.132 \ moles[/tex]
⟡ ⟡ ⟡
Thus, the number of moles oxygen gas reacted is 0,132 moles.

7. Find the number of moles of the indicated species: a) 333 mg of Na2B4O7.10H20
Jawaban:
Penjelasan:
[tex]\text{Na}_2\text{B}_4\text{O}_7.10\text{H}_2\text{O}[/tex]
Mr = 2Na + 4B + 8O + 20H
Mr = 2(23) + 4(11) + 17(16) + 20(1)
Mr = 46 + 44 + 272+ 20
Mr = 382
[tex]n = \frac{m}{Mm}\\n = \frac{333}{382}\\n = 0,87 \times 10^-3 \ \text{mol}[/tex]

9. 2.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?pakai cara ya jawabnya,yg salah di report,jangan asal jawab ya
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.

13. A mixture of 10 cm' of methane and 10 cm' of ethane was sparked with an excess of oxygen, After cooling to room temperature, the residual gas was passed through aqueous potassium hydroxide All gas volumes were measured at the same temperature and pressure. What volume of gas was absorbed by the alkali?
Jawaban:
Methane = CH4
Ethane = C2H6
//First off, we need to understand that when hydrocarbons get combusted, they produce CO2 and H2O.
//Now we'll need to write down the equation and balance it out like this:
CH4(g) + 2O2(g) ---> CO2(g) + 2H2O(l)
C2H6(g) + 3.5O2(g) ---> 2CO2(g) + 3H2O(l)
//From this equation, we know that the reaction produces CO2 as a residual gas.
//Then the question says that the residual gas is then passed through aqueous potassium hydroxide (KOH). Thus, we would also need to react the CO2 and KOH as shown:
CO2(g) + OH-(aq) ---> CO3(-2)(aq) + H2O(l)
//Volume of CO2 produced by CH4 and C2H6 is 10 and 20 cm^3 respectively. Thus, the total volume of CO2 produced is 30 cm^3

14. What affect the colours of the aurora?A. Gas.B. Electrons and gas.C. Nitrogen and oxygen.D. Oxygen and electrons.E. Electrons, nitrogen, and oxygen.
Jawaban:
E. Electrons, nitrogen, and oxygen
or elektron, nitrogen dan oksigen
Penjelasan:
The reaction between solar wind particles and the Earth's atmosphere, produces a variety of colors in the aurora. At altitudes above 300 km, solar wind particles will collide with hydrogen atoms to form a reddish aurora color. Increasingly, at an altitude of 140 km, solar wind particles react with oxygen atoms that form blue or purple auroras. Meanwhile, at an altitude of 100 km protons and electrons contact with oxygen and nitrogen atoms so that the aurora is visualized in green and pink
or
Reaksi antara partikel angin matahari dengan atmosfer bumi, menghasilkan berbagai macam warna pada aurora. Pada ketinggian di atas 300 km, partikel angin matahari akan bertumbukan dengan atom-atom hidrogen sehingga terbentuk warna aurora kemerah-merahan. Semakin turun, yakni pada ketinggian 140 km, partikel angin matahari bereaksi dengan atom oksigen yang membentuk cahaya aurora berwarna biru atau ungu. Sementara itu, pada ketinggian 100 km proton dan elektron bersinggungan dengan atom oksigen dan nitrogen sehingga aurora tervisualisasikan dengan warna hijau dan merah muda.

16. 0.08 moles of sulfuric acid in 2 litres of solution has a Ph?
n (moles) = M / V
M (concentracion) = n x V = 0,08 moles x 2 Litres = 0,16 M
Since H₂SO₄ is strong acid, we must use this formula:
[H⁺] = acid valence x Concentration
[H⁺] = 2 x 0,16 M
[H⁺]= 0,32 M = 32 x 10⁻² M
pH = - log [H⁺]
pH = - log (32 x 10⁻² M)
pH = 2 - log 32
~apply some logarithm properties~
pH = 2 - 5 log 2
pH = 0,5
That gives us pH of said acid is 2-5log2.
I hope this helps~
