Answer:
His third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A. Notice that the forces are exerted on different objects.
Explanation:
Answer:
Percentage by mass of calcium carbonate in the sample is 93.58%.
Explanation:
Assumptions:
- calcium carbonate was dissolved completely and the amount of carbon dioxide released was proportional to the amount of calcium carbonate.
- the sample did not contain any other compound that released or reacted with carbon dioxide.






given the equation of the reaction:

from assumption:
amount carbon dioxide = amount of calcium carbonate

reacting mass ( m ) = Molar Mass ( M ) * Amount ( n )

m = 0.04938397
* 100
= 4.93839 
percentage by mass of CaC
=
.
Incresing Pressure will increases the amount of gas dissolved !!
so your answer is B !!
Extra : Cool example is Pepsi or coke !! CO2 is dissolved by high pressure
No, the biosphere does not exhibit a clear boundary as life always comes to an end.
The biosphere comprises all the living things of the world, like all the plants and animals. It is considered as the global ecosystem, that is, the gathering of all the planet's ecosystems.
