✨ Magical Challenges ✨
Can you solve these mystery puzzles?
You have 18 g of glucose (C₆H₁₂O₆). How many hydrogen atoms are present in this sample? (Given: Avogadro's number = 6.022×10²³, atomic masses: C=12, H=1, O=16)
Consider the reaction: CH₄(g) + 2O₂(g) → CO₂(g) + 2H₂O(g). If you start with 16 g of CH₄ and 64 g of O₂, what mass of CO₂ is produced? (Atomic masses: C=12, H=1, O=16)
In the Bohr model of hydrogen, what is the energy (in eV) of the photon emitted when an electron jumps from n=3 to n=2? (Given: Eₙ = -13.6/n² eV)
