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

As long as the chemical is not used up in the reaction the answer is true
<span>The alkali metals and hydrogen are reactive because they have only one electron to give in order to complete their valence shell. It is easier to give that one electron so when given the opportunity they will. This means they will react with anything polar or willing to take an electron.</span>
