Answer:
The Deeper these nodules are, the harder it becomes. To use robotic submersibles eliminates the need for oxygen for people, but they would need an especially designed loader or mechanical “hands” to gather, and Balloons could Raise the mined Mn to the surface for collection.
Explanation:
Answer:
7.951 x 0²³atoms
Explanation:
Mass of Fe₃O₄ = 140g
Solution:
To find the number of oxygen atoms in iron(III) oxide, we first find the number of moles in the compound:
Number of moles = 
Molar mass of Fe₃O₄ = (3x56) + (4x64) = 168 + 256 =424g/mol
Number of moles = 
= 0.33mole
1 mole of an atom contains 6.02 x 10²³atoms
∴number of oxygen atoms in Fe₃O₄ = 4 x 0.33 x 6.02 x 10²³atoms
= 7.951 x 0²³atoms
Depression can affect a person psychologically, it also has the potential to affect physical structures in the brain. These physical changes range from inflammation and oxygen restriction, to actual shrinking. Depression can impact the central control center of nervous system. Depression can cause amygdala to enlarge. This is a part of the brain associated with emotional responses. When amygdala becomes larger and more active, it causes sleep disturbances, changes in activity levels, and changes in other hormones.
Answer:
An oxidizing agent (also called an oxidizer or oxidant) is referred to as a chemical compound that readily transfers oxygen atoms or a substance that gains electrons in a redox chemical reaction.
