How many atoms in 3.5 moles of Ca

Hey there!

There are 6.022 x 10²³ atoms of copper in one mole of copper.

So, multiply 6.022 x 10²³ by 3.5.

3.5 x 6.022 x 10²³

21.077 x 10²³

2.1077 x 10²⁴

There are 21.077 atoms in 3.5 moles of Ca.

Hope this helps!

b. atoms in metallic solids are not arranged in a regular pattern

explanation:

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
