Which compound below has the highest iron content?
Feo
FeCl2
FeSO4
Fe(OH)2
ANSWER:
Fe(OH)2
Explanation:
Fe(OH)2
The highest iron content.
A compound is a substance that consists of the atoms or the ions of the two or more different elements that are joined by a chemical bond and can't be separated by any physical means. Like water is a compound of oxygen and hydrogen.
This the answer is Fe(OH)2.
The highest iron content of the iron is the second iron hydroxide, and it is an inorganic compound that makes salts from a compound of iron sulfate. Has white sold traces of oxygen which gives it a greenish tint. It can be seen in its mineralogical forms as a form of green rusting.Hence the option D is correct.

In the first generation, the beetles with the dark spotted trait had a lower chance of
survival. The beetles changed their color to better adapt to their environment, and the
species evolved to have a lighter color.
Answer:
In the first generation, the beetles changed to have light spots. The beetles with the light spotted trait had a better chance of survival causing the species evolved to have lighter spots.
Answer:
In the first generation, the beetles with the dark spotted trait had a better chance of survival. The trait mutated over time, causing the beetles with that trait to be darker.
Explanation:
In the picture that I had, it shows that some of the beetles in the first generation started to develop spots on their back or wings. It shows that later down the line, their backs start to get even more darker which means that is must be a trait that mutated over time that would allow the beetles with that trait to be significantly darker. They can't just change their traits if they want to so it would have to be something like mutation that caused it.

4Na + O₂ → 2Na₂O
Given parameters:
Number of moles of O₂ = 6.97moles
Unknown:
Number of moles of Na₂O
Solution:
To solve this problem;
1 mole of O₂ will produce 2 moles of Na₂O ;
6.97 moles of O₂ will produce 6.97 x 2 = 13.94moles of Na₂O
6. An unknown compound is analyzed and found to consist of 49% carbon, 2.7
% hydrogen, and 48.2 % chlorine. If the molecular mass of the compound is 150,
what is the molecular formula of the compound?
Answer:
Molecular formula = C₆H₄Cl₂
Explanation:
Given data:
Percentage of hydrogen = 2.7%
Percentage of carbon = 49%
Percentage of chlorine = 48.2%
Molar mass of compound = 150 g/mol
Molecular formula = ?
Solution:
Number of gram atoms of H = 2.7 / 1.01 = 2.67
Number of gram atoms of Cl = 48.2 / 16 = 1.36
Number of gram atoms of C = 49 / 12 = 4.08
Atomic ratio:
C : H : Cl
4.08/ 1.36 : 2.67/1.36 : 1.36/1.36
3 : 2 : 1
C : H : Cl = 3 : 2 : 1
Empirical formula is C₃H₂Cl.
Molecular formula:
Molecular formula = n (empirical formula)
n = molar mass of compound / empirical formula mass
Empirical formula mass = 12×3 + 1.01 ×2 + 35.5 = 73.52 g/mol
n = 150 / 73.52
n = 2
Molecular formula = n (empirical formula)
Molecular formula = 2 (C₃H₂Cl)
Molecular formula = C₆H₄Cl₂

Answer:
The Answer is Precipitation
Explanation:
Look it up on and then also got it right on the Unit Test and the Quiz.
The diagram illustrates the water cycle, the process that occurs at location W is precipitation. The correct option is a.
What is precipitation?Precipitation is any product of the condensation of atmospheric water vapour that falls under gravitational pull from clouds. The main forms of precipitation include drizzle, rain, sleet, snow, ice pellets, graupel and hail.
Precipitation occurs when a portion of the atmosphere becomes saturated with water vapour so that the water condenses and precipitates or falls. Thus, fog and mist are not precipitation but colloids, because the water vapour does not condense sufficiently to precipitate. Two processes, possibly acting together, can lead to air becoming saturated: cooling the air or adding water vapour to the air. Precipitation forms as smaller droplets coalesce via collision with other raindrops or ice crystals within a cloud. Short, intense periods of rain in scattered locations are called showers.
Precipitation is a major component of the water cycle and is responsible for depositing the fresh water on the planet.
