The meaning and usefulness of the mole Page 2 2 • One mole of NaCl contains 6.022 x 1023 NaCl formula units. Use the mole quantity to count formulas by weighing them.
Answer:mole ratio between N2 and 2NH3 is 1:2while mole ratio between H2 and 2NH3 is 3:2
Explanation: 1 mole of N2 is required to produce 2 moles of NH3 while 3moles of H2 is required to produce 2 moles of NH3
The non-contact forces portfolio includes Gravitational force, Magnetic force and Electrostatic force.
<h3>What is non contact force?</h3>
Non contact forces are those forces which are applied on any object without any physical interference or contact.
Some non-contact forces are:
- Gravitational force: It acts between two objects and depends on the masses of the object and distance between that objects.
- Magnetic force: It acts due to the motion of the charged particles.
- Electrostatic force: It is a type of induced force which is generated due to rubbing of two objects but when it is generated it remains even after removing the contact of previous objects.
Hence Gravitational force, Magnetic force and Electrostatic force are the non-contact forces.
