The atomic mass of the element = 24.309547
<h3>Further explanation</h3>
Given
Isotopes of Mg
Required
The atomic mass
Solution
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
The atomic mass of the element(Mg) :
= 23.98504 . 0.7870 + 24.98584 . 0.1013 + 25.98259 . 0.1117
= 18.876226 + 2.531066 + 2.902255
= 24.309547
Answer:
The pOH of a solution is the negative logarithm of the hydroxide-ion concentration. The pH of a solution can be related to the pOH.
I looked it up, so idk if it is right...
false all element when they are combined eachother thier valance number will change
the combination of oxygen and aluminum gives us Al2O3 see even the numbers are changing thank you if you have a comment you can write
The biotic factors are bacteria soil, dead leaves, and stream water.
<h3>What is an abiotic factor?</h3>
An abiotic factor is a non-living part of an ecosystem that shapes its environment.
Biotic and abiotic factors make up a community via interaction.
Biotic factors are considered living things (having "life") while abiotic factors are simply non-living things.
The dead leaves of plants are an abiotic factor, the bacteria in soil are living matter and stream flowing, etc.
Hence, the biotic factors are bacteria soil, dead leaves, and stream water.
