The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
Answer:
The cell will shrink
Explanation:
In an hypotonic solution, water moves into the cell through the process of osmosis. This shall be due to the high concentration of water in the hypotonic solution than that in the cytoplasm.
Due to this movement, the cell bulges out.
If the cell is transferred to a hypertonic solution, water shall move out of the cell thereby making the cell shrink. This is because water concentration in the cytoplasm shall be higher than that in the hypertonic solution.
Effect to the survey shall be an experience of the exact opposite of the previous immersion.
Chemosynthesis, I believe. Bacteria at the bottom of the ocean use this process for food.
