In 5.70 mol of Hafnium there are 34,326
They meet all the environmental conditions an organism needs to survive
Color they look the same hope this helps.
it decreases the density of the object the air bubbles take up space. it increases the volume of the object slightly but the objects weight remains the same, hence the objects density decreases
Answer:
no.
Explanation:
The reason this has
never happened is due to the source of magnetic fields: moving electric
charges. When electric charges (e.g. electrons) move in circles, they
produce a magnetic field. In a piece of iron, it is very easy to line up
these circles, getting all the little magnets to work together as one big
magnet.
For each of these circles, one side is the north pole and one side is the
south pole. Since each circle has two sides, each circle has a north and a
south pole. Even the smallest possible magnets (spinning electrons) have a
north and a south pole.
