The reaction includes the single replacement reaction and redox
<h3>Further explanation</h3>
Single replacement : one element replaces another element in a compound
A + BC ⇒ AC + B
The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number
3CuCl + 2Al => 3Cu + 2AlCl₃
Al replacing Cu in the CuCl compound
3Cu²⁺ + 6e⁻⇒ 3Cu reduction(oxidation number from +2 to 0)
2Al⇒2Al³⁺+6e⁻ oxidation(oxidation number from 0 to +3)
The element involved in the process of petrification, replacement, and permineralization is silica, were petrification is the combination of 2 types of fossilization, replacement, and permineralization
Permineralization is a way of fossilization in which minerals ( like silica have deposited the fill the empty pores of shells or the hard animal parts). Petrification is a process where the organic material is converted to stone by replacing the original material and the pores with minerals, and Replacement occurs when the original bones or shells dissolve away and is replaced by a different mineral, which occurs along with permineralization, the whole process is called petrification.

As you proceed down the periodic table, the metallic character becomes stronger. This is because as the atomic radius increases, there is less attraction between the nucleus and the valence electrons due to the greater distance between them, making electrons simpler to shed.
Boron trifluoride is the correct name for compound BF3
The correct answer for this question is 'False'
Environmental science is not the study of the earth's natural hazards
What is Environmental science?
Environmental Science is the study of physical, chemical, biological components of earth's natural environment they include air, water etc.,
The Environmental science closely studies the human impact on the earth's environment.
This field of science also helps us to know about how science effects our environment.
And the 3 main aspects of Environmental science are:
To understand the interaction between humans and environment
To understand how natural world works
To Find a way to deal with the environmental problems to live sustainably.
