Salt is soluble in water.
The nucleus consists of protons and neutrons. Since neutrons are neutral, they are not taken account of in the net charge. The number of protons = the net charge of the nucleus and that is shown by the atomic number. For example, the atomic number of Oxygen is 8 which means that it has 8 protons; a net charge of +8 only in the nucleus. On a deeper note, a neutral atom has the same amount of protons as electrons, so theoretically, oxygen is supposed to have 8 valence electrons, but sometimes it has a deficiency of 2 electrons (making an oxygen ion), so the net charge would be -2 of the <em>whole</em> atom (since it's supposed to be neutral), but the net charge of the<em> nucleus</em> itself would still be +8.
So, sum of the forces (or net force) = MA
In order to solve this equation, we just plug our numbers in,
![\sum F=MA\\\sum F=1500kg\times2.0m/s\\\sum F= 3000N](https://tex.z-dn.net/?f=%5Csum%20F%3DMA%5C%5C%5Csum%20F%3D1500kg%5Ctimes2.0m%2Fs%5C%5C%5Csum%20F%3D%203000N)
3000N
Answer:
It is a reversible process.
Explanation:
Oxygen combines with haemoglobin and then deattaches from it.
