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
The answer is 1 polonium and radium
<span>Calcium. It is classified chemically as one of the alkaline earth elements. It is found in group two of the periodic table. It forms a white coating of calcium nitride (Ca3N2) in air. The symbol is classified as Ca. It is a metallic metal.</span>
Answer:
Neutral (no net charge)
Explanation:
Protons - Positive
Electrons - Negative
Neutrons - No charge
<em>Why? </em>
Neutrons are the particle in an atom with a (as the name suggests) neutral charge. They are neither positive nor negative, unlike protons or electrons.
