Plants, cellular respiration accurately represents a carbon source and the process that releases carbon from that source
<u>Explanation:</u>
Every existing body supplies CO2 off while they evoke power from their food through cellular respiration. Plants and creatures present off CO2 while living and respiring and during lifeless and rotting. Plants are significant carbon sinks, gaining up enormous volumes of CO2 through the manner of photosynthesis.
While plants also discharge CO2 during the means of respiration, the volume of CO2 exercised up by plants by photosynthesis and discharged by exhalation approximately matches out. Volcanic action, forest wildfires, and diverse anthropological exercises deliver carbon.
Simple distillation is a method for separating the solvent from a solution. For example water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point then salt. When the solution is heated the water evaporates
The charge on the tin ion is the same as the Roman numeral in the Stock name.
SnO₃ = tin(VI) oxide
Sn₂O₅ = tin(V) oxide
SnO₂ = tin(IV) oxide
Sn₂O₃ = tin(III) oxide
SnO = tin(II) oxide
Sn₂O = tin(I) oxide
Each oxide ion has a charge of -2.
To get the charge on a tin ion, you calculate the <em>total charge</em> on the O ions. Then you <em>change the sig</em>n and <em>divide by the number of Sn ions</em>.
E.g., for <em>Sn₂O₅</em>: Charge on 1 O = -2; charge on 5 O = -10; charge on 2 Sn = +10; charge on 1 Sn = +5.
2 molecules of Acetaldehyde is the product of a reaction of an alkene. One way in which alkenes can react to give carbonyl compounds (ketones/aldehydes) is the reaction with ozone, O₃. The ozonolysis of an alkene will result in cleavage of the carbon-carbon double bond and each carbon that was part of the alkene, will now have a double bond to oxygen. Each carbon of the original alkene will now be a carbonyl in the product.
To form 2 molecules of acetaldehyde, we must cleave an alkene that has the same substitution pattern on each side of the alkene so that the carbonyl compounds formed are identical. Therefore, both (E)- and (Z)-2-butene will react with ozone to give acetaldehyde. The scheme provided shows the reaction of both alkenes to give the acetaldehyde. The products are drawn in such a way to show which part of the original molecules they were derived from. However, both reactions do provide identical products.
Answer:
Explanation:
Absolute dating uses for example, radiocarbon dating method to tell the numeric age of an organic substance and this is not always exact. In the other hand, relative age dating give a more precision since it is comparing the age of a particular part of the substance to the other parts. For example, comparing the lower layer of a rock to the upper layer, it is certain that the lower layer is older than the upper one.
