0.69moles
Explanation:
Given parameters:
Number of atoms = 4.14 x 10²³atoms
Atom = Na
Unknown:
Number of moles of Na atom in it = ?
Solution:
A mole of a substance is the quantity of substance that contains the avogadro's number of particles.
1 mole = 6.02 x 10²³particles
To solve this problem, simply use the expression below;
Number of moles = 
Input the parameters;
Number of moles = 
= 0.69moles

In the context of chemistry, yes. Energy input is always equal to the energy output.
<h3><u>Answer;</u></h3>
C. 300 N
<h3><u>Explanation</u>;</h3>
From Newton second's Law of motion, the resultant force is directly proportional to the rate of change in momentum.
Therefore;
F = ma ; where F is the resultant force, m is the mass and a is the acceleration.
Therefore;
F = 0.06 kg × 5,000 m/s/s
<u>= 300 N</u>
You have many different ways possible. If you have a freezer in the classroom you could do that. If you made it really cold in the room and stopped all air flow in the room so it stayed cold you would be able to freeze it.
