The diameter of a neutral helium atom is about 1 x 10^2 pm. suppose that we could line up helium atoms side by side in contact with one another. approximately how many atoms would it take to make the distance 1 in from end to end?

helium atoms will be needed to cover 1 inch distance.

Explanation:

Diameter of helium atom =

1 m = 39.3701 inch

Then in

Diameter of helium atom in inches =

Let the number of helium atoms required to cover 1 inch distance be x.

Total distance = 1 inch

helium atoms

helium atoms will be needed to cover 1 inch distance.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
