The main points of Dalton's atomic theory are: Everything is composed of atoms, which are the indivisible building blocks of matter and cannot be destroyed. All atoms of an element are identical. The atoms of different elements vary in size and mass.
Commensalism is the relation ship between two species where one of the species is being benefited while the other is not benefited and not even harmed.
It is a type of symbiosis
the correct answer is
A) Birds feed off the insects that are stirred up from the grasses as cattle move through.
Electrons might be the answer
Answer: As magma cools and crystallizes minerals form is predictable patterns in a process known as '<em>Bowen reaction series'.</em>
Explanation:
The sequence in which minerals crystallize out from the magma is Bowen's reaction series. The top most layer of the magma will crystallize first and slowly successive layers will cool down to form crystals.
The newly formed mineral from the cooling magma reacts again with the remaining magma further to form another series of minerals.
A molecular property of the Group 6A(16) hydrides changes abruptly down the group. This change has been explained in terms of a change in orbital hybridization can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group).
We can see a similar difference in Group 15 as well where the same thing influences stability through bond strength (decrease in bond dissociation enthalpy down the group). The change is a significant decrease in \textbf{bond angle}bond angle. Down the group we're observing increase in size as well as decrease in electronegativity which causes position of bond pairs of electrons to shift more and more away from the central atom. That then causes a decrease in repulsion between bonded pairs which results in a decrease in bond angle hydrides.
