<span>The ocean is primarily a liquid and the atmosphere is mostly gas, so they are different states of matter. They also have different chemical compositions which really ought to be common knowledge. Also, very few fish swim in the sky.

Answer:</h3>
2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂
<h3>
Explanation:</h3>
- A decomposition reaction is one in which a large compound is broken down into smaller compounds or individual elements.
- The decomposition reaction Iron (iii) hydrogen carbonate yield iron (iii) carbonate, water and carbon dioxide.
Fe(HCO₃)₃ → Fe₂(CO₃)₃ + H₂O + CO₂
- A balanced equation is the one in which the number of atoms of each element are equal on both side of the equation.
- Therefore; the balanced equation for the decomposition of Iron (iii) hydrogen carbonate is given by;
2Fe(HCO₃)₃ → Fe₂(CO₃)₃ + 3H₂O + 3CO₂
Answer:
- <u>Second choice: </u><em><u>How does the position of the Sun, moons, planets and stars affect a person's personality traits and daily behavior patterns?</u></em>
<u></u>
Explanation:
Science or scientific investigations deal with objective phenomena; this is phenomena which can be described by using objective measurements.
The effect of the position of the Sun, moons, planets and stars on a person's personality and daily behavior patterns is not a scientific question because none scientific field deals with that kind of questions.
Only, a pseudoscience, this is a set of beliefs that have not been scientifically proved, may deal with a question about the effect of the position of some heavenly objects can affect a person's personality traits and daily behavior of patterns.
On the other hand, the aspects deal with in the other questions (the mass of a toy car, the speed down a ramp, the heating from different type of pans, how different type of chemicals remove the cell wall of a plant cell) are measurable and testable (falsifiable), which make them objects of science (like physics, chemistry, and biology)
Atomic mass Ti = 47.867 a.m.u
47.867 g ---------------- 6.02x10²³ atoms
33 g --------------------- ??
33 x ( 6.02x10²³) / 47.867 => 4.15x10²³ atoms
Answer D
hope this helps!
Answer:
I believe the answer is: C a bear living in a hollowed-out log.
Because:
The bear is living and the hollowe-out-log isn't.
