4. What reagent would you predict to be in excess for reacting 7.50 mL of a 0.10M BaCl2 solution with 7.50 mL of 0.10M KIO3 solution

Answer : reagent predict to be in excess.

Explanation : Given,

Concentration of = 0.10 M

Volume of = 7.50 mL = 0.0075 L       (1 L = 1000 mL)

Concentration of = 0.10 M

Volume of = 7.50 mL = 0.0075 L

First we have to calculate the moles of  and .

and,

Now we have to calculate the excess and limiting reagent.

The balanced equilibrium reaction will be:

From the balanced reaction we conclude that

As, 2 mole of react with 1 mole of

So, 0.00075 moles of react with moles of

From this we conclude that, is an excess reagent because the given moles are greater than the required moles and is a limiting reagent and it limits the formation of product.

Hence, reagent predict to be in excess.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
