what actually is left over of water once it self ionizes? Like what exactly are the hydrogen and hydroxide ions? Do they remain
GrogVix [38]
The formula for the self ionization of water is 2H₂O(l)⇄H₃O⁺(aq)+OH⁻(aq)

The hydronium (H₃O⁺) is usually just referred to as a hydrogen ion or a proton (H⁺) and hydroxide (OH⁻) doesn't have another name that I am aware of.  These ions do stay in solution.  However the concentrations are really small and the equilibrium constant (K(w)) is 1×10⁻¹⁴.

I hope this helps.  Let me know if anything is unclear.

A standard soft drink can has a volume of 0.355 L. An empty can is sealed while
beks73 [17]

Answer:

0.35 atm

Explanation:

To solve this problem, we use Boyle's Law: P_1V_1=P_2V_2 , where P is the pressure and V is the volume.

Here, V_1 = 0.355 L, P_1 = 1.0 atm, and V_2 = 0.125 L. So, just plug these values into the equation:

(1.0) * (0.355) = P_2 * (0.125)  ⇒  P_2 ≈ 0.35 atm

Thus, the pressure is 0.35 atm.

Hope this helps!

Scientists often work on projects for a long time and fail to see sources of error in their research. Which process allows an ou
prohojiy [21]

Answer:

The correct approach is Option B (Peer Review).

Explanation:

  • Rather made reference to someone as a scientific peer-review, it encourages the specialist who has not been essential to the study team to analyze the study objectively and pointed out everyone's mistakes. It serves as major self-regulation for scholars and aims to make the publishing process somewhat credible. Hence, the solution to this issue is Peer Examination.
  • Funding organizations rarely have the capabilities to recognize out mistakes, whereas definitive analysis is a method of study that helps to make a definitive statement. The gathering of data is simply a process of scientific study.

Other approaches do not apply to the example mentioned. Although the one mentioned is right.
