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
Answer: Government regulation, healthcare, telemarketing, environmental engineering, banking.
Explanation:
Science is the set of objective and verifiable information about all areas of human knowledge. To create knowledge, science uses the scientific method, this method explains, formulates and verifies a hypothesis about a concept.
Science can be used in all professional fields because it allows for obtaining objective information or knowledge. For example, in government regulation, the scientific method can be implemented to make objective decisions about decisions that will best help the population.
I hope this information can help you.
You should know how many electrons fit in each shell.
K 2
L 8
M 2
You can fit 8 electrons in the M shell but after filling up the first shells, there are only 2 electrons left. This means that there are 2 valence electrons.
As mentioned above, the characteristic chemical property of a metal atom is to lose one or more of its electrons to form a positive ion. However, certain metals lose electrons much more readily than others. In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li).
Answer:
During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel, glucose and other sugars for building plant structures. This process forms the foundation of the fast carbon cycle.In all four processes, the carbon dioxide released in the reaction usually ends up in the atmosphere.
