Explanation:
A small rock falling from a cliff is an example of physical weathering. The process breaks the rock mass into small chips of rocks.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- In physical or mechanical weathering, lumps of rocks are broken down into small sizes.
Some of the process involves:
- Pressure release on a rock
- Freezing and thawing
In chemical weathering, a rock undergoes chemical reactions and it becomes weak in the process.
Some of the process involves:
- oxidation
- hydrolysis
- carbonation

Answer:
26.81 moles
Explanation:
From the coefficients of the equation, we know that for every 2 moles of iron(III) oxide produced, 7 moles of oxygen are consumed.
So, the answer is 7.66(7/2), which is 26.81 mol.
It is either a proton or a neutron . B
<h3>
How to identify the particle</h3>
The particle labeled with an X is a neutral atom or a proton which is symbolically represented as :
AZX
where,
Z = atomic number of the element and is known as the number of protons and number of electron (in the particle)
A = Mass number of the element which is represented as the sum of the protons and neutrons (in the nucleus)
Thus, the statement that best identifies the particle X is that it is either a proton or a neutron
