A nuclear reaction releases more energy per gram and appears to violate the law of conservation of mass.
Explanation:
In nuclear reactions there arises a shift in the nucleus of the atom. This results in the production of a different element altogether. While in chemical reactions the electrons are rearrangement and there is no change in the nucleus.
Factors like temperature, pressure, and catalysts do not affect the rate of nuclear reactions while they influence the chemical reactions.
The change in the energy is higher in nuclear reactions. It arises out of the destruction of mass.
In the group 3 to group 12 of elements, it is the d subshell
that filled up going across the rows,.
In the d-block of the periodic table, we have the Zinc, Cadmium, and
Mercury. This corresponds to the teams 3
to 12 of the periodic table.
A double-edged stainless steel can float on water. Without surface tension, the blade would sink because its weight is greater than its buoyant surface.
Answer: The blade doesn't sink because of the surface tension of the water.
