Figure out and understand how exactly you learn and process things and information then simply take it from there.
Read the books given to you and Bing/Google search things of your questioning. Read over the things you will be tested on, Get some nice study music on (something you enjoy nothing to genetic), read your books, quiz yourself to make sure you understand and take these ideas and create your own solutions through figuring out how you'd like to get ready.
The time it takes for 1g of strontium-90 to decay to 250 mg is; 57.6 years
<h3>What is the half life of an element?</h3>
The formula for half life is;
A(t) = A₀ * (¹/₂)^(t/t_1/2)
Where;
A(t) is amount left after t years
A₀ the initial quantity of the substance that will undergo decay;
t_1/2 is the half-life of the decaying quantity.
We are given;
t_1/2 = 28.8 years
A₀ = 1 g
A(t) = 250 mg = 0.25 g
Thus;
0.25 = 1 * (¹/₂)^(t/28.8)
log 0.25 = (t/28.8) log (1/2)
-0.60206 = (t/28.8) * -0.3010
t = 2 * 28.8
t = 57.6 years

The process that releases carbon dioxide into the atmosphere is called cellular respiration. In this process, carbon dioxide is emitted or produced along with other metabolites such as lactic acid, aldehydes, acetic acids, and other kinds.
Explanation:
Respiration and decay return carbon to the atmosphere. Fossil fuels (oil, coal, and natural gas) are fashioned from buried remains of organisms. The burning of fossil fuels conjointly releases carbon into the atmosphere.cellular respiration could be a set of metabolic reactions and processes that crop up within the cells of organisms to convert organic chemistry energy from nutrients into ATP(ATP), and so unleash waste merchandise.
