Reaction
2AgNO₃ + Cu ⇒ Cu(NO₃)₂ + 2Ag
mol silver (Ag): 95.3 : 108 g/mol = 0.882
mol copper nitrate (Cu(NO₃)₂): 82.9 : 187.5 g/mol = 0.441
mol Ag = 2 x mol Cu(NO₃)₂, so 0.441 being the mole basis of the reactants
mol Cu = 0.441
mass Cu = 0.441 x 63.5 g/mol = 28 g
mol AgNO₃ = 0.882
mass AgNO₃ = 0.882 x 170 g/mol = 149.94 g
The two different mineral elements that a fertilizer can contain are:
- Phosphorus - build up of nucleic acid and ATP
- Nitrogen- synthesis of proteins
<h3>What are fertilizers?</h3>
Fertilizers are chemical substances added to the soil in order to improve crop growth and development.
Fertilizers are artificially made to contain mineral elements that are needed by the plants. Some of the mineral elements are as follows:
- Phosphorus
- Nitrogen
- Pottasium
- Phosphorus helps in the build up of nucleic acids and ATP for energy.
- Nitrogen is useful in the synthesis of proteins.

Answer:
Explanation:
Acetylene is an organic compound consisting of only carbon and hydrogen atoms, also known as a pure hydrocarbon.
Every hydrocarbon might undergo either an incomplete or a complete combustion. In an incomplete combustion, carbon monoxide is produced along with water, while in a complete combustion, there's enough oxygen to oxidize the resultant carbon monoxide to carbon dioxide.
In a complete combustion of acetylene, it reacts with oxygen to produce carbon dioxide and water:
The difference between the two is, cleavage is the property of a mineral that allows it to break smoothly along specific internal planes (called cleavage planes) when the mineral is struck sharply with a hammer. Fracture is the property of a mineral breaking in a more or less random pattern with no smooth planar surfaces.

Answer:
Between oxygen and selenium, oxygen is more electronegative because of more ionisation energy and small size
