Question 30select the correct answer from each drop-down menu. a reaction proceeds with 2.72 moles of magnesium chlorate and 3.14 moles of sodium hydroxide. this is the equation of the reaction: mg(clo3)2 + 2naoh → mg(oh)2 + 2naclo3. determine the theoretical amount of each product that the reaction will produce. the reaction will produce of magnesium hydroxide and of sodium chlorate. (both have the same dropdown) a. 1.36 b. 1.57 c. 2.72 d. 3.14 e. 4.52 (all in moles)

well #1 is A

and #2 is E  

well i did just do this

Answer : The reaction will produce (B) 1.57 mole of magnesium hydroxide and (D) 3.14 mole of sodium chlorate.

Explanation :

First we have to calculate the limiting and excess reagent.

The balanced chemical reaction is,

From the balanced reaction we conclude that

As, 1 moles of react with 2 mole of

So, 2.72 moles of react with moles of

That means, in the given balanced reaction, is a limiting reagent because it limits the formation of products and is an excess reagent.

Now we have to calculate the moles of and by using the moles of limiting reagent.

As, 2 moles of react to give 1 mole of

So, 3.14 moles of react to give moles of

And,

As, 2 moles of react to give 2 mole of

So, 3.14 moles of react to give 3.14 moles of

Therefore, the reaction will produce (B) 1.57 mole of magnesium hydroxide and (D) 3.14 mole of sodium chlorate.
