Answer:
The solubility of CuX is 1.425x10⁻⁷M
Explanation:
Given:
initial concentration of NaCN=0.2M
Ksp=1.27x10⁻³⁶
The reaction are:
CuX → Cu²⁺ + X²⁺, Ksp=1.27x10⁻³⁶
Cu²⁺ + 4CN⁻ → (Cu(CN)₄)²⁻, Kf=1x10²⁵
The overall reaction is:
CuX + 4CN⁻ → (Cu(CN)₄)²⁻ + X²⁺
The equilibrium constant is:
K=Ksp*Kf=1.27x10⁻³⁶*1x10²⁵=1.27x10⁻¹¹
CuX + 4CN⁻ → (Cu(CN)₄)²⁻ + X²⁺
I - 0.2 0 0
C - -4 +x +x
E - 0.2-4 x x
The equation for equilibrium is:
Here, solving for x:
x=1.425x10⁻⁷M=CuX

Manganese (II) carbonate and oxygen reacts to give manganses (III) oxide with carbon-dioxide gas.
..(2)
Manganese (III) oxide reacts with aluminum metal to give aluminum oxide and manganese metal
On adding (1) and 2(2) we will get the net net chemical equation for the production of manganese. So,
The net balanced equation we got:
Final answer:
The production of manganese from manganese (II) carbonate, oxygen, and aluminum involves two chemical reactions. Heating manganese (II) carbonate with oxygen yields manganese(III) oxide and carbon dioxide. This manganese (III) oxide then reacts with aluminum to produce manganese and aluminum oxide.
Explanation:
The chemical reaction can be described in terms of a net chemical equation after properly balancing the chemicals involved on both sides of the equation. The first step is to understand and correctly write down the formula of reactants and products for the reaction. Here: Manganese (II) Carbonate (MnCO3), Oxygen (O2), and Aluminum (Al).
In the process of manganese production, Manganese (II) Carbonate is first heated in the presence of oxygen to yield Manganese (III) Oxide (Mn2O3) and Carbon Dioxide (CO2):
MnCO3 + 1/2 O2 -> Mn2O3 + CO2.
The resulting Manganese (III) Oxide reacts with Aluminum (which acts as a reducing agent in this case) to generate Manganese and Aluminum Oxide:
3 Mn2O3 + 4 Al -> 6 Mn + 2 Al2O3.
These two equations combined represent the net chemical equation for the production of manganese from manganese (ii) carbonate, oxygen, and aluminum.

Answer:
This is required answer.
Explanation:
Given that,
1,2,3,4,5,6-hexachlorocyclohexane
(a). We need to draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in axial positions
Using given data
We draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in axial positions.
When we say that all the chloro groups in axial position that means axial bonds are vertical.
(b). We need to draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in equatorial positions
Using given data
We draw 1,2,3,4,5,6-hexachlorocyclohexane with all the chloro groups in equatorial positions.
When we say that all the chloro groups in equatorial position that means axial bonds are horizontal.
Hence, This is required answer.

SO₃+ H₂SO₄ → H₂SO₄ This reaction is synthesis type of reaction, because that would be combination (synthesis) A + B → AB. Therefore, option A is correct.
What are the types of reaction ?
There are five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.
Biochemical reactions are chemical reactions that occur within living things. Metabolism refers to the sum of all biochemical reactions in an organism. Exothermic and endothermic chemical reactions are both part of metabolism.
Hydration is the process of combining water molecules with another substance to form a single, new compound. SO3 is an acidic oxide that reacts with and dissolves in water to form sulfuric acid, H2SO4.
Thus, option A is correct.

Answer:
6.1 kg
Explanation:
To obtain the total mass of the sample, we must first express each mass of the sample in the same unit of measurement.
Since the SI unit of mass is kilogram (kg), we shall express the total mass of the samples in kilogram (kg).
This is illustrated below:
Mass of the samples are:
M1 = 0.6160959 kg
M2 = 3.225 mg
M3 = 5480.7 g.
Conversion of 3.225 mg to kg
1 mg = 1×10¯⁶ kg
Therefore,
3.225 mg = 3.225 × 1×10¯⁶
3.225 mg = 3.225×10¯⁶ kg
Conversion of 5480.7 g to kg
1000 g = 1 kg
Therefore,
5480.7 g = 5480.7 /1000
5480.7 g = 5.4807 kg
Thus, we can obtain the total mass of the samples as follow:
M1 = 0.6160959 kg
M2 = 3.225×10¯⁶ kg
M3 = 5.4807 kg
Total mass =?
Total mass = M1 + M2 + M3
Total mass = 0.6160959 + 3.225×10¯⁶ + 5.4807
Total mass = 6.096799125 ≈ 6.1 kg
Therefore, the total mass of the samples is approximately 6.1 kg.
