Chlorine has 7 electrons, so in order to both have 8, they need to share 2 electrons.:)
Mixing sea water with silver nitrate solution than a white solid called (Silver chlorie) AgCl will form. Sodium nitrate is also a product but it is dissolved in the water. AgNO3 + NaCl→AgCl + NaNO3
2NaCl + F2 -> 2NaF + Cl2 The first F in the equation has 2, so the second has to have 2 as well. But placing a 2 before the NaF, gives the Na 2. So add a 2 before the NaCl. and the Cl after the yield sign already has 2.
yes they have changed as in the oldern days, we did not have all the helpfull things that we have now days including chemical to keep the water clean such as chlorie,=which prevent any viruses and bacteria; entering the pool and onto other people.==we have provided test to help the water.==back in 1940 there was fungi and infections spreading fast now the numbers are decresing as time goes by!=
