Answer:
answer is A. Alkaline metal lose two electrons not gain
By hot springs, fumaroles and geysers.
The much hydrogen that is produced is 0.02 mol of H₂ (answer B)
Explanation
2K +2H₂O→ 2 KOH + H₂
Use the mole ratio to determine the moles of H₂
From equation above the K :H₂ is 2:1
Therefore the moles of H₂ = 0.04 x 1/2 = 0.02 mol of H₂
Answer:
Yes
Explanation:
Standard temperature and pressure conditions are defined as 1 atm pressure and 273.15 K. On the other hand, standard ambient temperature and pressure conditions are defined as 1 atm pressure and 298.15 K.
Notice, however, that the only change between them is in temperature.
In any standard conditions, the standard atmospheric pressure is equal to 1 atm.
At sea level, the atmospheric pressure is also equal to 1 atm.
Therefore, we may conclude that the standard atmospheric pressure is equivalent to the normal air pressure at sea level. With an increase in altitude, however, the atmospheric pressure decreases.
