none of the above. is the answer
Answer:
Baking, microwave, heating system for your house, water boiler, fridge.
You must use 1880 mL of O₂ to react with 4.03 g Mg.
A_r: 24.305
2Mg + O₂ ⟶ 2MgO
<em>Moles of Mg</em> = 4.03 g Mg × (1 mol Mg/24.305 g Mg) = 0.1658 mol Mg
<em>Moles of O₂</em> = 0.1658 mol Mg × (1 mol O₂/2 mol Mg) = 0.082 90 mol O₂
STP is 25 °C and 1 bar. At STP, 1 mol of an ideal gas has a volume of <em>22.71 L</em>.
<em>Volume of O₂</em> = 0.082 90 mol O₂ × (22.71 L O₂/1 mol O₂) = 1.88 L = 1880 mL
Frequency = velocity (aka speed) / wave length
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
