Determine how many grams of silver would be produced, if 12.83 x 10^23 atoms of copper react with an excess of silver nitrate. G

likoan [24]

<u>Answer:</u> The amount of silver produced in the given reaction is 459.63 g.

<u>Explanation:</u>

According to mole concept:

1 mole of an atom contains $6.022\times 10^{23}$ number of atoms.

For the given chemical equation:

$Cu+2AgNO_3\rightarrow Cu(NO_3)_2+2Ag$

By Stoichiometry of the reaction:

1 mole of copper produces 2 moles of silver.

This means that, $6.022\times 10^{23}$ number of atoms of copper produces $2\times 6.022\times 10^{23}$ number of atoms of silver.

So, $12.83\times 10^{23}$ number of atoms of copper will produce = $\frac{2\times 6.022\times 10^{23}}\times 12.83\times 10^{23}=25.66\times 10^{23}$ number of atoms of silver.

We know that:

Mass of 1 mole of silver = 107.87 g

Using mole concept:

If, $6.022\times 10^{23}$ number of atoms occupies 107.87 grams of silver atom.

So, $25.66\times 10^{23}$ number of atoms will occupy = $\frac{107.87g}{6.022\times 10^{23}}\times 25.66\times 10^{23}=459.63g$

Hence, the amount of silver produced in the given reaction is 459.63 g.

0.513 mol Al2O3 = g Al2O3

Dovator [93]

Answer:

Molar mass (M) = mass(m) / number of moles (n)

To find the mass of Al2O3 first calculate it's molar mass

thus

M(Al2O3) = (27×2) + (16 × 3)

= 54 + 48

= 102g/mol

Mass of Al2O3 = molar mass × number of moles

= 102 × 0.513

= 52.326g of Al2O3

29) What type of chemical reaction is given by the following balanced equation: Al2O3 → Al + O2

Law Incorporation [45]

Decomposition.

Decomposition is the chemical reaction in which a compound breaks down into the two elements or molecules that formed the compound. In this case, Dialuminium Trioxide has broken down into the basic components of Al2 and O2.
