Question

19. Alisha conducted an experiment in which she poured warm water into four different bottles labelled A, B, C and D as shown in the image below. She then added one, two, three and four tablespoons of yeast in them respectively. She shook the bottles gently and replaced the caps with balloons. She observed that all the four balloons inflated to different sizes. a. What is causing the balloon to inflate? b. Identify the reaction and write the word equation for the reaction that would have occurred in each of these bottles. c. Where else do you see microorganisms release gases? Is the released gas useful? Where is it used? ​

Answer 1

Answer:

5 mL/min

Explanation:

Given,

Given,Amount of water = 200 mL

Given,Amount of water = 200 mLPercolation time = 40min

Given,Amount of water = 200 mLPercolation time = 40minRate of percolation = Amount of water in mL / Percolation time in min

Given,Amount of water = 200 mLPercolation time = 40minRate of percolation = Amount of water in mL / Percolation time in min =200 / 40

Given,Amount of water = 200 mLPercolation time = 40minRate of percolation = Amount of water in mL / Percolation time in min =200 / 40 =5 mL/min.

Given,Amount of water = 200 mLPercolation time = 40minRate of percolation = Amount of water in mL / Percolation time in min =200 / 40 =5 mL/min.Hence, the rate of percolation of water through the given soil sample is 5 mL/min.
