Answer:
B. decay of dead marine organisms
Explanation:
When the temperature is low, carbon dioxide is captured by the oceans, and when the temperature is high, it is released by the oceans into the atmosphere. At sea, carbon dioxide feeds phytoplankton.
Most of the carbon dioxide consumed by plant plankton (phytoplankton) returns to the atmosphere when this phytoplankton dies or is consumed, but a portion is deposited in the ocean floor sediments when these small particles sink. This process is called a "biological bomb" because carbon dioxide is transported from the atmosphere to the ocean floor.
Your hypothesis is not the scientific question in your project. The hypothesis is an educated, testable prediction about what will happen. Make it clear. A good hypothesis is written in clear and simple language. ... (For more information about identifying variables, see: Variables in Your Science Fair Project
Answer:
6.79 atm
Explanation:
Applying Dalton's law of partial pressure:
, where
= total partial pressure of all the component gases in the mixture,
= partial pressure of helium gas, and
= partial pressure of oxygen gas.
From the illustration,
= 7.00 atm and
= 0.21 atm. Hence, the partial pressure due to helium is calculated such that:
= 
= 7.00 - 0.21
= 6.79 atm
<em>Therefore, the partial pressure due to helium in order to maintain the pressure due to oxygen at 0.21 atm would be </em><em>6.79 atm.</em>
Answer:
<h3>The answer is 11.88 moles</h3>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula

where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have

We have the final answer as
<h3>11.88 moles</h3>
