Explanation:
A redox reaction equation shows a gain/loss of electrons from left to right in a reaction. In a redox reaction, a specie looses electrons while another specie gains electrons.
Considering the equation; 2Al(s) + 3Cu(NO3)2(aq) -----> 3Cu(s) + 2Al(NO3)3(aq)
The oxidation state of Al reactant is zero since the oxidation state of all uncombined elements is zero. The oxidation state of All in the product is +3
The oxidation state of the copper in the reactant is +2. The oxidation state of copper in the product is zero.
The oxidation state of N in the reactant and product is +5.
The oxidation state of oxygen in the reactant and product is (-2).
This is a redox reaction because from left to right, Al was oxidized (oxidation number increased from zero to +3) while Cu was reduced (oxidation number decreased from +2 to zero).
The major drawback of fossil fuels is that they warm the planet i.e. they cause global warming.
The reaction typically gives off heat and light as well. The general equation for a complete combustion reaction is:
Fuel + O2 → CO2 + H2O + ENERGY

Disadvantages of Fossil fuels</h3>
The term "fossil fuels" refers to flammable organic geologic formations, including dead organic matter that has been buried hundreds of feet beneath sediment.
- Fossil fuel emissions include various oxides, such as carbon, nitrogen, and sulfate, which cause acid rain and harm the soil's fertility and water quality.
- Both coal and petroleum burning discharge a significant amount of pollutants into the atmosphere, contributing to pollution levels.
- Gases like carbon dioxide are released through the burning of fossil fuels, which aids in climate change.

Answer: Bromine is Actually a Halogen!
Explanation: Bromine is in the 7th column of the Periodic Table. It needs that magic 8 valence electrons and it has 7.
Hoped that helped!
Answer:
The answer is a compound.
it is a compound as it contains different elements
Explanation:
Answer:
The mass of an object is the same no matter where it is, but the weight of an object changes with the location of that object. For example, the weight of an object on the Moon is 1/6th that of the same object on Earth, while the mass of that object is exactly the same in both places.
