Answer:
The terms used to describe the given process in <em><u>Chemical weathering.</u></em>
Explanation:
Weathering of rock is defined as breaking down of the rock into small pieces.
There are two types pf weathering :
Mechanical weathering : This weathering is due to change in physical parameters : temperature change, pressure change etc.
For example : When water soaked up in cracks or crevices of rocks freezes it expands and physically breaks the rock.
Chemical weathering : This weathering is decomposition of rocks due to action of chemicals.This type of weathering also changes chemical composition of rocks.
For example : when gases like carbon dioxide, sulfur oxide get dissolves in water present in rock to form weak acid which ease up the dissolving of rock in that weak acid.
Answer:
In chemistry, a structural isomer (or constitutional isomer in the IUPAC nomenclature) of a compound is another compound whose molecule has the same number of atoms of each element, but with logically distinct bonds between them. The term metamer was formerly used for the same concept.
Explanation:
Foolow me amd if you think i am correct make me brainlist
so:
so:
it means that
in
of acid there is
moles of acid
so:
it means that:
in
of water there is
moles of water
therefore:
So your answers are:
and the mole fraction is:
Answer:
The mass of present is
Explanation:
From the question we are told that
The diameter of the spot is
The volume of the solution present is
The mass of ions in one liter of solution is
Generally the mass of ions present is v is mathematically represented as
Converting to nanograms
We have
Energy equals mass times the speed of light squared
