D Earth's core contains mostly iron and nickel
I will use this conversion:
1m = 1000 mm => 1 = 1m / 1000mm
1 m = 100 cm=> 1 = 1m / 100cm
1m = 10 dm=> 1 = 1m / 10 dm
So,
B) 3.8 * 10^7 cm^3 = 3.8 * 10^7 cm^3 * [1m / 100cm]^3 = 38 m^3
C) 3.8 * 10^5 dm^3 * [1m / 10 dm]^3 = 380 m^3
D) 3.8 * 10^8 mm^3 * [1m / 1000 mm]^3 = 0.38 m^3
Now you can compare the four volumes and conclude which is the largest.
Answer: option C) 3.8 * 10^5 dm^3
Answer:
The Florian predict the metamorphic rocks because it changes when subjected to heat and pressure.
Explanation:
i hope this helps
In conclusion, modeling is very useful for predicting molecular polarity because chemical bonds among different atoms are generated to equal electrical charges.
<h3>What is molecular polarity?</h3>
Molecular polarity refers to the unequal distribution of electrical charges in the atoms of a molecule.
This unequal distribution leads to the generation of molecular poles (positive and negative) at the ends of the chemical bonds.
In conclusion, modeling is very useful for predicting molecular polarity because chemical bonds among different atoms are generated to equal electrical charges.
