For the following reaction, 6.79 grams of hydrogen gas are mixed with excess iodine . The reaction yields 775 grams of hydrogen iodide . hydrogen ( g ) iodine ( s ) hydrogen iodide ( g ) What is the theoretical yield of hydrogen iodide

Explanation:

Hello.

In this case, for the reaction:

As 6.79 g of hydrogen (molar mass = 2.02 g/mol) react in excess iodine, we can compute the theoretical yield of hydrogen iodide (molar mass = 127.91 g/mol)  via their 1:2 mole ratio shown on the chemical reaction:

Next, we compute the percent yield by divinding the actual yield (775 g) by the theoretical yield (860 g):

Best regards!

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.
