The atmospheric pressure will be:
The pressure of the atmosphere resulting from the mercury column is 0.959 atm
What is atmospheric pressure?
The force that an object experiences from the weight of the air above it per unit area are known as atmospheric pressure.
Given: Height of mercury column = 729 mm Hg
To find: The pressure of the atmosphere
Calculation:
The atmospheric column resulting from the mercury column is calculated as follows:
1 atm =760 mm Hg
So, we can convert the 729 mm Hg to atm, and we get
Atmospheric pressure = 729 x 1 atm / 760 = 0.959 atm

Answer:
True
Explanation:
They are built from particles and blobs of congealed lava ejected from a single vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as cinders around the vent to form a circular or oval cone, making them the simplest out there
Cu-63 and Cu-65 have 34 and 36 neutrons, respectively, in each atom. 27- Because copper has an atomic number of 29, which essentially implies that an atom of copper has 29 protons and 29 electrons, an atom of copper has a total of 29 electrons.
The stable isotope of copper is copper-63, which has a nuclear spin of 3/2, a relative atomic mass of 62.929601, and a natural abundance of 69.2 atoms. a trace element of a heavy metal having the atomic symbols Cu, 29, and 63.55. This atom has the mass number 63 because it is a copper-63 atom. Every atom of a particular element has the same atomic number, which may be determined as the element's number on the predictable.
