What would happen if you added more than 5 mL of H2O2 to the 5 mL of yeast solution?

Answers

Answer 1
Answer:

Answer:

The hydrogen peroxide would dissociate down into oxygen and water.  

Explanation:

The hydrogen peroxide dissociates into oxygen and water.  

2H₂O₂ → 2H₂O + O₂

The yeast comprises an enzyme known as catalase that catalyzes the reaction. Greater the concentration of the catalyst supplemented, the faster will be the decomposition of the hydrogen peroxide. Therefore, if one adds more than 5 milliliters of H₂O₂ to the yeast solution, the dissociation would take place at a quicker rate, and the bubbles and the accompanying fizz would be in a higher amount.  
Answer 2
Answer:

The yeast breaks down the hydrogen peroxide (H2O2) into oxygen and water.

The half-life of cobalt-60 is 5.3 years. after __________ years, 1/4 of the original amount of cobalt-60 will remain.

Answers

The  number of  years  required  for 1/4  cobalt-60  to remain   after   decay  is calculated  as follows

  after  one  half life  1/2 of the original  mass isotope  remains

after  another half life 1/4  mass  of  original  mass  remains

therefore  if one  half  life is  5.3   years  then  the  years required

= 2  x 5.3years =  10.6   years

Answer:

10.6
