CH2(OH)CH2(OH), b. p. = 197°C (nonvolatile) What is the f. p. of a solution consisting of 651g EG in 2505g H2O? Would you keep this solution in the car radiator during the summer? MW = 62.01 kf = 1.86°C/m kb = 0.52°C/m

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

i think its 100

i hope this !

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
