Half-life is a first-order reaction which means the rate of decay is constant. Using the supplied value of the half-life of 14c (5715 years), and that the <span>piece of ancient charcoal contains only 20% as much of the radioactive carbon as a piece of modern charcoal, the calculated "age" or timespan when the tree got burned is </span>13269.819062281 or simply, 13270 years ago.
Answer:
Organizing and displaying data are important in statistics. After data are collected, the data may not make sense just looking at them. That is why it is important to organize and display the data using tables or graphs.
Explanation:
Answer:
Percent yield = 114.5%
Explanation:
Given data:
Calculated amount of product/ theoretical yield = 55 g
Actual amount of product after performing reaction = 63 g
Percent yield = ?
Solution:
Formula:
Percent yield = ( actual yield / theoretical yield )× 100
by putting values,
Percent yield = (63 g/ 55 g)× 100
Percent yield = 114.5%
