Answer;
Iodine
Explanation;
Electron configurations are a way of keeping track of the location of the electrons around the nucleus.
Iodine is an element which belongs to the halogen family. The halogen group includes fluorine, chlorine, bromine, astatine, and iodine.
A neutral iodine atom would also have 53 electrons. Its ground state electron configuration would be:
1s22s22p63s23p64s23d104p65s24d105p5
Morality= wt\m.wt*1000\v(ml)
So the m.wt of h3po4 is 98.00g\ml
Molarity = 32.7g\98.00*1000\455ml
=0.7176

on g00gle duhh just look it up. :)
Answer:
1) Yes
2) No
Explanation:
A strip of solid magnesium metal is put into a beaker of 0.053M ZnSO4 solution-YES
A chemical reaction occurs
Mg(s) + ZnSO4(aq) ----------> MgSO4(aq) +Zn(s)
This reaction is possible because magnesium is far higher than zinc in the activity series of metals hence magnesium can displace zinc from a solution of a zinc salt.
A strip of solid zinc metal is put into a beaker of 0.058M MgBr2 solution. NO
A chemical reaction does not occur because magnesium is higher than zinc in the activity series hence zinc cannot displace magnesium from a solution of its salt.
For the constituents of a mixture, they retain their individual properties meaning iron remains magnetic and sulfur remains a non metal and non metallic.
