The reaction of 68.2 gram of O2 with excess of C4H8O produced 27.9 grams of H2O. What is the percent yield if 25.8 g of H2O was actually produced in the lab?

i dont k

Explanation:

...

Explanation:

64.0g O2 1mol O2 2mol H2O 18.02g H2O

32.00 g O2 1mol O2 1mol H2O

= 72.08 g H2O = 72.1 g H2O

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
