Answer: Mass is more than 145 g but less than 160 g
Explanation: Acid and limestone reacts forming water, salt and
Carbon dioxide CO2. Because CO2 is gas it is bubbled away from
glass and that's why mass is less than 160 g. Because limestone
releases CO2 and products from acid remain in solution, mass is more than 145 g. If amount of acid in moles is enough, all limestone reacts.
Roughly 44% of mass of limestone CaCO3 forms CO2 and we can estimate mass of gas is 0.44·15 g = 6,6g , so mass would be 153 g
Because the results are consistent
Answer:
The clarification of the hypothetical is outlined in the following portion.
Explanation:
- Cellular respiration would be the predominant mechanism justification for transferring chemical resources, and perhaps the reagents/products associated with cell respiration have become glucose, CO2, and water.
- Although the basic functionalities responsible for cell oxygenation can vary from individual to individual, a few other sorts of cell respiration have always been performed by all living creatures.
