Answer:

The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy.

Answer:

here is what i put for this project:

The reaction in this project is exothermic. The energy change in a chemical reaction is due to the difference in the amounts of stored chemical energy between the products and the reactants. This stored chemical energy, or heat content, of the system is known as its enthalpy. The potential energy in reactants is higher than the potential energy of products in an exothermic reaction. Since energy is given off, the products are lower in energy than the reactants. The energy that is given off is a result of the formation of new bonds.

The change of the enthalpy happening in the chemical reaction is different from the pathway in between the initial and the final states. The addition of the equation gives the net change of the enthalpy. Enthalpy change is the amount of heat evolved or absorbed in the reaction under constant pressure. This can be calculated by checking the amount of heat evolved during the reaction. This reaction occurs at a constant pressure.

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.
