Answer:
6.022 X 10^23
Explanation:
avatars number states that for every mole of an element there are 6.p22 X 10^23 atoms of that element
<span>Water is known as a polar molecule because the oxygen atom has a greater attraction for electrons than the hydrogen atom does. Oxygen is more electronegative than that of hydrogen creating a partial charges with the hydrogen and oxygen atoms. Also, the electrons of the covalent bond are not shared equally between the hydrogen and oxygen atoms making it polar.</span>
Alfred Wegener
proposed the continental drift theory in
four reasons. One, he hypothesized that the continents were once a giant
continent. Two, he observed that there are fossils found of the same kind in
the different locations. Three, he found that the edge of opposing continents
somehow fits if they are combined, almost like a puzzle. And four, there are
glacial scars that are left behind by a larger glacial continent. His greatest
weakness of Alfred Wegeners’ continental drift theory was he could not explain
what kind of force that caused this continents to move far from each other.
