Answer:
Age of the tool = 15411.75 years
Explanation:
Assume half life of 14C = 5730 years
Calculate rate constant using formula:
thus 
Assuming initial concentration, Co of 14C = 100%
Final concentration, C of 14C = 15.5%
Use formula:
thus
t = 15411.75 years

Ethanol contains an alcohol group (-OH), which includes hydrogen bonding. Hydrogen bonding is stronger than other IMFs such as Van der Waals forces and Dipole-Dipole.
Ethene only has Van der Waals forces as it is an alkene with only C-H or C-C bonds. These means that the forces are not as strong.
Since ethanol contains hydrogen bonding, it will take a higher temperature in order to break these bonds, and thus results in a higher boiling point than ethene.
Answer:
Grass, trees, and flowers.
Explanation:
A producer converts the suns energy to make its own food, and a producer uses photosynthesis.
Answer:
The total number of atoms when glucose and oxygen reacts stays the same when carbondioxide and water are produced.
Explanation:
Chemical reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O
We can see that the number of atoms of each element remain same on both side of reaction so law of conservation of mass is followed by this reaction. Six number of carbon atoms twelve number of hydrogen atoms and eighteen number of oxygen atoms are present on both side.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide
This process use respiratory electron transport chain as electron acceptor instead of oxygen. It is mostly occur in prokaryotes. Its main advantage is that it produce energy (ATP) very quickly as compared to aerobic respiration.
