The principle of conservation of mass is true. For reactants in both open and closed system. When a chemical reaction takes place in an open system. matter can enter from or escape to the surroundings
Answer:
Option (C)
Explanation:
Sedimentary rocks are those rocks that are formed due to the compaction and lithification of sediments.
When the rocks are weathered by the agents such as wind, water and ice, the sediments or the particles are carried from that particular area to a different place. The sediments are then continuously deposited in a different place. As a result of which the sediments are accumulated over one another, forming layers. These sediments over a due course of time undergoes compaction and solidification due to the weight of the overlying rocks. This is how the sedimentary rocks are formed. Some of the examples of sedimentary rocks are sandstone, limestone, shale, and mudstone.
Thus, the correct answer is option (C).
Answer: b. They are composed of molecules that contain carbon-carbon bonds.
c. They undergo chemical reactions to use energy they acquire from the environment.
Living things includes all the organisms that display features which make them distinct from non-living organisms. The living organisms have an organized structure, they are composed of cells, they require energy to survive or sustain existence, they are able to reproduce and they exhibit ability to grow.
They are composed of molecules that contain carbon-carbon bonds: Carbon is the main component present in all living things. They make up the organic biomass of these living organisms.
They undergo chemical reactions to use energy they acquire from the environment: The plants traps sunlight energy and converts it into food and lastly into chemical energy in the form of ATP. This ATP is used as a energy reservoir for metabolic processes occurring in the plants. Therefore, energy is generated after chemical reactions.
