Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products.
<u>Explanation</u>:
- The carbon cycle is the procedure where carbon goes from the surrounding into living beings and to the Earth and then again goes into the air. Plants take carbon dioxide from the air and use it for food preparation. Creatures at that point eat the nourishment and carbon is put away in their bodies or discharged as CO2 through the breath.
- Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products. This is known as carbon storage.
- For instance, carbon, a fundamental component in natural particles, is preserved as it is moved from inorganic carbon in a biological system to natural atoms in living life forms of the biological system and back as inorganic carbon to the earth.
Answer:
D.
Explanation:
That would be the last option.
Repeated similar experimental outcomes are confirmation of the theory.
Answer:
C. H2SO4 I did the instruction
Answer:
The volume of NaOH used
Explanation:
The tip of the buret is part of its calibration. If this tip is not filled before taking the initial reading, <u>the volume of NaOH used at the end of the titration would be inaccurate. </u>
<em>In order to avoid this, the valve of the buret should be opened and the NaOH allowed to displace whatever air that might have been trapped at the tip before the initial buret reading is taken and the titration is carried out. </em>
Mass of iron: 86.65
Moles of iron: 85.65 / 56 = 1.53
Mass of oxygen: 118.37 - 86.65 = 32.72
Moles of oxygen: 32.72 / 32 = 0.99 1.02
The molar ratios of the two are approximately similar; therefore, Dawson's conclusion is more correct.
