<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 
number of atoms.
For the given chemical equation:
By Stoichiometry of the reaction:
1 mole of copper produces 2 moles of silver.
This means that, number of atoms of copper produces 
number of atoms of silver.
So, 
number of atoms of copper will produce = 
number of atoms of silver.
We know that:
Mass of 1 mole of silver = 107.87 g
Using mole concept:
If, number of atoms occupies 107.87 grams of silver atom.
So, 
number of atoms will occupy = 
Hence, the amount of silver produced in the given reaction is 459.63 g.
Answer:
The mechanical energy produced on burning fossil fuels is transformed into chemical energy stored in carbon dioxide.
Explanation:
When fossil fuels are burnt, mechanical energy is produced. Remember that according to the first law of thermodynamics, energy is neither created nor destroyed but can be transformed from one form to another. Hence the mechanical energy produced when fossil fuels are burnt for industrial use, heating of homes, electricity generation , cooking etc the mechanical energy produced is not 'lost'. It must be transformed in to another form of energy.
In the image the arrow G----> C, shows the mechanical energy produced when fossil fuels are burnt are stored as chemical energy in CO2 bonds. CO2 is found in the atmosphere, hence the arrow point upwards from the source towards the atmosphere (C is the atmospheric reservoir of CO2). The energy is subsequently used by producers to produce chemical energy stored in food.
Answer:
The degree of compactness of a substance
The heat of reaction is 1.8 KJ. A calorimeter is a device used in calorimetry, a procedure for calculating heat capacity and measuring the heat of chemical processes or other physical changes.
<h3>How to calculate calorimeter?</h3>
- A calorimeter is a device used in calorimetry, a procedure for calculating heat capacity and measuring the heat of chemical processes or other physical changes.
- Among the most popular kinds are differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters, and accelerated rate calorimeters.
- Calorimeter, a tool for estimating a material's heat capacity and measuring the heat produced during a mechanical, electrical, or chemical reaction. bomb thermometer.
Volume of water = 67.9 mL
Since the density of water is 1.00 g/mL
Density = mass/volume
Mass of water = Density × volume
Mass of water = 1 g/mL × 67.9 mL
Mass of water = 67.9g or 0.0679 Kg
Temperature change = 6.5 oC
Specific heat capacity of water= 4.184 J/Kg
From;
H = mcθ
m = mass of water
c = heat capacity of water
θ = temperature rise
Substituting values;
H = 0.0679 Kg × 4.184 J/Kg × 6.5 oC
H = 1.8 KJ
