Answer :
0.125 g
Explanation : If you are calculating the half life of P-32 which has half life of 14.3 days and you want to calculate how many grams are remaining after 71.3 days if yo are starting with 4 g?
starting you can calculate the number of half life P-32 undergoes first,
which is n = 71.5 / 14.3 = 5 days.
now, to calculate the remaining mass,
=
Both take carbon dioxide out of the atmosphere.
The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.
Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.

Answer:
C. Hydrogen Ions.
Explanation:
The pH level of soils is measured based upon the acidity or basicity level in the soil. The pH scale usually measures between 0-14. 7 is the neutral pH level of soil and a pH level below 7 is considered acidic and above 7 is alkaline.
So, soil with a high amount of hydrogen ions (H+) will be considered acidic. As the amount of hydrogen ions increases in the soil, the pH level of the soil decreases, making it acidic.
Therefore, option C is correct.

Because density=mass/volume, the density of a substance would increase if the mass was increased and the volume was not, and decreased if the volume was increased and the mass was not.
