Answer:

8

Explanation:

If strontium has a half-life of 3 hours and you have 64 grams of it that means every 3 hours strontium's grams will be divided by 2.

So you have 64/2 = 32 for the first half life   {Time is currently at 3 hours}

32/2 = 16 for the second half life {Time is currently 6 hours}

Then you have 16/2 = 8 for the third half-life {Time is currently 9 hours}

How is molarity affected if some solution splashes out of the flask during titration?
Annette [7]
<span>If you used more water, the molarity would go down since molarity is moles/liter, and the opposite if you used more water. 

If the acid absorbed water, the molarity would go down because the absorbed moisture will skew the weight of the acid up. 

That would make the molarity go down since there would have been unreacted acid in the spilled liquid.</span>

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Ber [7]

Answer:

The biological pump or the marine carbon pump is the title for multiple processes leading to separation of carbon from multiple sources of water. Biological pumping is partially responsible for the cycling of organic matter. This process can lead to loss of contact between carbon and the atmosphere for thousands of years.

Hope this helped!

How does ph affect enzyme-catalyzed reactions?
Ilya [14]
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis. In geneal enzyme have a pHoptimum. However the optimum is not the same for each enzyme
