<h3>What does a hydrogen atom contain?</h3>
- The hydrogen atom is the most fundamental of all atoms because it just contains one proton and one electron.
- In addition to this most common isotope, the hydrogen atom can also be found in protium, deuterium, and tritium.
- Hydrogen, denoted by the letter H, has the first atomic number among the lightest elements.
<h3>How do you describe a hydrogen atom?</h3>
- There are three known hydrogen isotopes.
- Hydrogen has isotopes with masses of 1, 2, and 3, with mass 1 being the most common.
- This isotope is also referred to as protium and hydrogen in everyday language (symbol H, or 1H).

Answer:
Heat energy required (Q) = 10.736 KJ
Explanation:
Given:
Specific heat of ethanol (C) = 2.44 J/g °C
Mass of ethanol (M) = 50 gram
Initial temperature (T1) = -20°C
Final temperature (T1) = 68°C
Find:
Heat energy required (Q) = ?
Computation:
Change in temperature (ΔT) = 68°C - (-20°C)
Change in temperature (ΔT) = 88°C
Heat energy required (Q) = mC(ΔT)
Heat energy required (Q) = (50)(2.44)(88)
Heat energy required (Q) = 10,736 J
Heat energy required (Q) = 10.736 KJ
