Lamps light up by electricity. Although, i'm sure you knew that by now. When a light bulb connects to an electric power supply, an electric current flows between the two metal contacts. As electricity flows between the wires and filament, the filament heats up. The filaments begin to emit photons, which are essentially small packets of light.
Hope this helps!

The question in English is:
<em>5. From 100 g of a compound formed by carbon, hydrogen and oxygen, 39.132 g of water and 95.656 g of CO₂ are obtained. Determine:</em>
<em />
<em>A. The empirical formula of the compound.</em>
<h2>Solution</h2>
All the carbon of the compound ends as carbon in the CO₂ and all the hydrogen in the compound ends in the water.
<u>1. C in CO₂</u>
Divide the mass of CO₂ by its molar mass and multiply by the molar mass of C:
<u>2. H in H₂O</u>
Divide the mass of H₂O by its molar mass and multiply by 2 times the molar mass of H:
<u>3. Calculate O by difference</u>
<u>4.Divide the mass of each element by the corresponding atomic mass to find the number of moles of the element</u>
- C: 26.379g / (12.011g/mol) = 2.196 mol
- H: 4.379g / (1.008g/mol) = 4.344 mol
- O: 69.242g / (15.999g/mol) = 4.328 mol
<u />
<u>5. Divide by the least number of moles</u>
Those are the subscripts of the empirical formula:
<u>6. Empirical formula</u>
The density is the ratio of the substance's mass to its volume. Density is an extensive property even though mass and volume are both intensive properties. It is because density is constant for each substance at a specified temperature and pressure. The equation is
Density = mass/volume
Substituting the values,
1.40 g/cm³ = [500 mg * (1 g/1000 mg)](Volume)
Volume = 0.357 cm³

Answer: Option (D) is the correct answer.
Explanation:
A fusion reaction is a reaction in which two small nuclei combine together to form a larger nuclei. Whereas in fission reaction, a heavier nucleus divides into lighter or small nuclei.
Fission reaction occurs due to absorption of energy whereas fusion reaction occurs due to the release of energy.
Fission reaction produces much more energy as compared to fusion reactions.
Thus, we can conclude that fusion reactors require less energy than fission reactors do is NOT an advantage of using a fusion reaction instead of a fission reaction to produce energy.
