Answer:

0.2 mole

Explanation:

From the question given above, the following data were obtained:

Number of molecules = 12.06×10²²

Number of mole =?

From Avogadro's hypothesis,

6.02×10²³ molecules = 1 mole

Therefore,

12.06×10²² molecules = 12.06×10²² / 6.02×10²³

12.06×10²² molecules = 0.2 mole

Thus, 12.06×10²² molecules is equivalent to 0.2 mole

Explanation:

Answer:B

Explanation:

Explanation:

If we compare its solubility products without any calculation then, Magnesium hydroxide is more soluble than compound A and C. Magnesium hydroxide is less soluble than compound D.

- The solubility product of magnesium hydroxide and zinc carbonate is same so it is not possible to determine whether it is more or less soluble than compound B

Answer:

20.9grams

Explanation:

Using the formula:

Q = m × c × ∆T

Where;

Q = amount of heat (joules)

m = mass of substance (g)

c = specific heat of water (4.184 J/g°C)

∆T = change in temperature (°C)

According to the provided information;

Q = 3.5kJ = 3.5 × 1000 = 3500J

m = ?

c of water = 4.184 J/g°C

∆T = 66°C - 26°C = 40°C

Using Q = m × c × ∆T

m = Q ÷ (c × ∆T)

m = 3500 ÷ (4.184 × 40)

m = 3500 ÷ 167.36

m = 20.9

mass = 20.9grams

Explanation:

Answer: The coefficient for water after the equation is balanced is 2.

Explanation:

The balanced chemical equation must have same charge and same number of atoms on both sides of the equation.

As the given reaction is a redox recation occuring in acidic medium.

[tex]HNO_3+3Fe^{2+}+3H^+\rightarrow NO+3Fe^{3+}+2H_2O[/tex]

The coefficient for water will be 2 after the equation is balanced.

Answer:

0.263 mole of NaOH

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

2Na + 2H₂O —> 2NaOH + H₂

From the balanced equation above,

2 moles of Na reacted to produce 2 moles NaOH.

Finally, we shall determine the number of mole of NaOH produced by the reaction of 0.263 mole sodium, Na. This can be obtained as follow:

From the balanced equation above,

2 moles of Na reacted to produce 2 moles NaOH.

Therefore, 0.263 mole of Na will also react to produce 0.263 mole of NaOH.

Thus, 0.263 mole of NaOH was obtained from the reaction.

its a polymer

Explanation:

Answer:

0.559 L

Explanation:

Step 1: Given data

Step 2: Calculate the volume of solution (V)

The molarity is equal to the moles of solute divided by the liters of solution.

M = n/V

V = n/M

V = 0.405 mol/(0.724 mol/L) = 0.559 L

The volume in Litres of a 0.724 M Nal solution that contains 0.405 mol of Nal is 0.56L.

Answer:

20.93 g

Explanation:

From the question given above, the following data were obtained:

Heat (Q) = 3.5 KJ

Initial temperature (T₁) = 26°C

Final temperature (T₂) = 66°C

Mass (M) =?

Next, we shall convert 3.5 KJ to J. This can be obtained as follow:

1 KJ = 1000 J

Therefore,

3.5 KJ = 3.5 KJ × 1000 J / 1 KJ

3.5 KJ = 3500 J

Next, we shall determine the change in the temperature of the water. This is illustrated:

Initial temperature (T₁) = 26°C

Final temperature (T₂) = 66°C

Change in temperature (ΔT) =?

ΔT = T₂ – T₁

ΔT = 66 – 26

ΔT = 40 °C

Finally, we shall determine the mass of the water. This can be obtained as follow:

Heat (Q) = 3500 J

Change in temperature (ΔT) = 40 °C

Specific heat capacity (C) = 4.18 J/gºC

Mass (M) =?

Q = MCΔT

3500 = M × 4.18 × 40

3500 = M × 167.2

Divide both side by 167.2

M = 3500 / 167.2

M = 20.93 g

Therefore, the mass of the water is 20.93 g

0.126923 mol Au ≈ 0.127 mol Au

Answer:

[tex]\boxed {\boxed {\sf 0.127 \ mol \ Au}}[/tex]

Explanation:

To convert from mass to moles, the molar mass must be used. This can be found on the Periodic Table.

Use this number as a ratio.

[tex]\frac {196.96657 \ g\ Au }{1 \ mol \ Au}[/tex]

Multiply by the given number of grams.

[tex]25.0 \ g \ Au*\frac {196.96657 \ g\ Au }{1 \ mol \ Au}[/tex]

Flip the fraction so the grams of gold will cancel.

[tex]25.0 \ g \ Au*\frac {1 \ mol \ Au}{196.96657 \ g\ Au }[/tex]

[tex]25.0*\frac {1 \ mol \ Au}{196.96657 }[/tex]

Answer:

0.046 mol

Explanation:

Step 1: Write the balanced equation

Fe₂O₃ + 2 Al ⇒ 2 Fe + Al₂O₃

Step 2: Calculate the moles corresponding to 3.6 g of Fe₂O₃

The molar mass of Fe₂O₃ is 159.69 g/mol.

3.6 g × 1 mol/159.69 g = 0.023 mol

Step 3: Calculate the moles of Fe produced from 0.023 moles of Fe₂O₃

The molar ratio of Fe₂O₃ to Fe is 1:2.

0.023 mol  Fe₂O₃ × 2 mol Fe/1 mol Fe₂O₃ = 0.046 mol Fe
