Answer: Heating the hydrated forms of cobalt chloride reverses the reactions above, returning cobalt chloride to the blue, water-free, or anhydrous, state. Water is "liberated" in these reactions, known as dehydration reactions.
Explanation:
Answer:
platinum-189 symbol is PT
25*5= 225 and 7hs hsueuxn udneicj
The balanced chemical reaction is:
<span>2HC2H3O2(aq) + Ba(OH)2(aq) + ----> 2H2O(l) + Ba(C2H3O2)2(aq)
We are given the amount of </span><span>HC2H3O2 to be used in the reaction. This will be the starting point for the calculation.
</span> 0.461 mol HC2H3O2 ( 1 mol Ba(OH)2 / 2 mol HC2H3O2<span> ) = 0.231 mol Ba(OH)2</span>
