Hydrogen + oxygen -> water
2H2 + O2 -> 2H2O (balanced)
2 moles of hydrogen gas will react with 1 mole of oxygen to produce 2 moles of water.
following that ratio, 0.734 mole of oxygen must need 0.734 × 2 moles of hydrogen to fully react.
answer is 1.468 moles of hydrogen.
Answer:
i believe it's C.
Explanation:
if it's wrong i apologize, if you are looking for an "Extensive tabulation of absorption coefficients of heated air including both molecular and atomic contributions" the equation can be used to calculate that step
Answer:
D. 6.25 J
Explanation:
∴ k = 50 N/m
∴ Δx = 0.5 m
⇒ EPE = 1/2*50 N/m*(0.5m)²
⇒ EPE = 6.25 N.m = 6.25 J
Answer:
No
Explanation:
There is no possible physical way for there to be an object without the molecules moving. There is a temperature called <u><em>absolute zero</em></u>,* however, there will always be some form of heat to touch everything, so nothing will ever be "frozen solid."
- (*) By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
