Answer:
Mass = 64 g
Explanation:
Given data:
Mass of water produced = 36 g
Mass of oxygen needed = ?
Solution:
Chemical equation:
CH₄ + 2O₂ CO₂ + 2H₂O
Number of moles of water produced:
Number of moles = mass/molar mass
Number of moles = 36 g/ 18 g/mol
Number of moles = 2 mol
Now we will compare the moles of water and oxygen.
H₂O : O₂
2 : 2
Mass of oxygen:
Mass = number of moles × molar mass
Mass = 2 mol × 32 g/mol
Mass = 64 g

Superconductors are materials that transfer energy with no resistance. Metals are usually the best conductors.
Superconductivity is a phenomenon characterized by zero electrical resistance at below critical temperatures. Metals are the best conductors because the molecules inside them are tightly packed, which allows electricity to travel efficiently.
Water is also a good conductor because of the ions and minerals in it. However, water itself is not a conductor of electricity.
