<span>A physical change basically involves a change in physical properties. Some examples of physical properties include: texture, shape, size, color, volume, mass, weight, etc.
The water melting has changed the shape and therefore it's physical properties, but the chemical nature of the water has not been altered.
So that's why it's a physical change, and not a chemical change.</span>
1. The coefficient (green) is 45
2. The exponent (yellow) is 9
<h3>Conversion scale</h3>
To convert from giga grams (Gg) to grams (g), the following coversion scale can be use:
1 Gg = 10⁹ g
With the above convesion scale, we can convert 45 Gg to g as follow
1 Gg = 10⁹ g
Therefore,
45 Gg = 45×10⁹ g
Thus, 45 Gg is equivalent to 45×10⁹ g. Hence, we can conclude as follow:
- The coefficient (green) is 45
- The exponent (yellow) is 9

Answer:4.42 g= 1 mol/55.845 =.079 moles of Fe
Explanation:Given 4.42 grams of Fe. The atomic weight of Fe(iron) found on the periodic table is 55.845. Divide grams by the atomic weight to convert to moles.
Answer:
First oil well in the United States, built in 1859 by Edwin L. Drake, Titusville, Pennsylvania.
Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.
<h3>What is Latent Heat ? </h3>
The heat that is released or absorbed during a phase change of a substance is known as Latent heat.
<h3>What is Hurricanes ?</h3>
Hurricanes is basically a type of storm called a tropical cyclone. These are intense low pressure areas. Hurricanes derive their energy from the latent heat of CONDENSATION.
Thus from the above conclusion we can say that Hurricanes derive their energy from the Latent heat of condensation.
Hence, Option (1) is correct answer.
