Answer:
grams
Explanation:
Given -
Half life of the silicon-32 
years
Half life means the time period required by a radioactive element to reduce its mass by half.
Radioactive decay formula is
Where
A represents the amount of radioactive element after time t years
represents the initial amount of radioactive element
time of decay
half-life of the substance
Substituting the given values in above equation, we get -
grams
A: Carbon dioxide
B: Carbon dioxide
C: Water and carbon dioxide, Oxygen, a by-product of photosynthesis, and water vapor exit the leaf.
D: the production of chlorophyll, the green pigment in plant leaves that converts energy from light into the carbohydrates plants feed on.
E: Precious Minerals.
A s solution that has more OH- than H+ is known as a basic solution.
<h3>What is an hydroxide ion (OH-)?</h3>
A hydroxide ion is a chemical ion the contains ions of hydrogen and oxygen with - 1 as it's oxidation number.
When a compound that contains excess OH- is added to a solution it will cause an increase in the basic nature of the solution.
This is because the OH- has the ability to accept protons when in a aqueous solution thereby leading to the rise in pH of that solution.
Increase in pH of a solution signifies an increase in basic characteristics.
