There are negative ions and positive ions known as anions and cations.
Atoms of elements (besides the noble gases) are not stable.
These atoms lose or gain electrons to gain the stable electronic configuration of a noble gas which has either 2 electrons or 8 electrons in the valence shell.
Since an atom is neutral, once it loses or gain electrons, it gains charge and is known as an ion
Species adapt to fit there environment in order to ensure the survival of the species in the long run
Answer:
84.259 kPa
Explanation:
We know that:
1 kPa is approximately equal to 7.5 mmHg
Therefore, to convert 632 mmHg to kPa, we will simply use cross multiplication as follows:
1 kPa .................> 7.5006 mmHg
?? kPa ................> 632 mmHg
632 mmHg = (632*1) / (7.5006) = 84.259 kPa
Hope this helps :)
Answer:
we have two loops in our body in which blood circulates. One is oxygenated, meaning oxygen rich, and the other is deoxygenated, which means it has little to no oxygen, but a lot of carbon dioxide.
