Help pls! The electrolysis of water forms H2 and O2.

2H2O Right arrow. 2H2 + O2

What is the percent yield of O2 if 10.2 g of O2 is produced from the decomposition of 17.0 g of H2O?

Use Percent yield equals StartFraction actual yield over theoretical yield EndFraction times 100..

15.1%

33.8%

60.1%

67.6%

Numbers with a end value of 4 or lower are rounded up, while with an end value of 5 or higher are rounded down. true or false?

Write a hypothesis that answers the lesson question, “while observing a chemical reaction, how can you tell which reactant is limiting? ” hypothesis: if a substance is the limiting reactant, then . . because . .

You exhale co2 which is produced during cellular respiration.  co2 combines with the water in your blood's plasma to make up one half of the body's most important buffer pair, carbonic acid.  the more physical activity you engage in, the more co2 your body is producing.  you can see this by putting some of the cabbage indicator in a glass and then blowing bubbles into it through a straw.  can you see a change in the color of the indicator?
