Perhaps when they are trying to find the distance of an asteroid to the Earth to find out whether or not it is a hazard to Earth.
Since the content of the closed is only hydrogen sulfide (H2S) it is then concluded that the initial pressure will still be equal to the pressure at the equilibrium state. Therefore, the answer to this item is 0.224 atm.
Answer:
We call solutions with more H+ than OH- acidic. pH is minus the common (base 10 ) logarithm of the hydrogen ion concentration and pOH is minus the log of the hydroxyl ion concentration. Hence pH + pOH = 14.
Explanation:
Answer:
Al2 O3 or 2:3
Explanation:
The aluminum oxide consists of two elements, which are oxygen atoms and aluminum atoms, and there are 2 aluminum atoms and 3 oxygen atoms in aluminum oxide. The ratio from aluminum atoms to oxygen atoms is 2:3.
