Pretty sure it's D. El Nino but not positive.
Answer:
19) 3.6920 × 10⁻⁵
20) 4.059× 10²
21) 2.46810121416 × 10³
22) 1.0000× 10⁻³
Explanation:
Scientific notation is the way to express the large value in short form.
The number in scientific notation have two parts.
The digits (decimal point will place after first digit)
× 10 ( the power which put the decimal point where it should be)
For example:
0.000036920
In scientific notation = 3.6920 × 10⁻⁵
405.9
In scientific notation = 4.059× 10²
2468.10121416
In scientific notation = 2.46810121416 × 10³
0.0010000
In scientific notation = 1.0000× 10⁻³
precipitation, it is called precipitation
D = m/v. v = (3)^3 = 27.
D = 27/27. D = 1g/cm^3
Answer: FeO is called ferrous oxide while Fe2O3 is ferric oxide
Explanation:
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 elections in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons to share. Ferric oxide, is commonly known as iron(III) oxide
