How many grams are there in 7.4x10^23 molecules of Na2SO4?

Answers

molar mass Na2SO4 = 142.04 g/mol

142.04 g -------------- 6.02x10²³ atoms
?? g ------------------ 7.4x10²³ atoms

142.04 x ( 7.4x10²³) / 6.02x10²³

=> 174.60 g

What two forces act in the nucleus to create a 'nuclear tug of war'?

Answers

In Nuclei, There are 2 forces. 1 force is electrostatic and acts as repulsion between 2 protons. The other is force of attraction called Nuclear force between 2 neutrons. This nuclear force is a short range force and is so strong that it negates the effect of the force of repulsion between the protons and helps bind the nucleus together. Hope this helped :D

Imagine that an uncharged pith ball is brought into the electrostatic field of a charged tod. The side of the pith ball closest to the negatively charged end of the rod will

Answers

When an uncharged pith ball is brought into the electrostatic field of a charged tod, the side of the pith ball closest to the negatively charged end of the rod will also gain a negatively charged surface. Then, it will not attract to the charged tod but rather it will repel.
