Answer:

D. An ion that is not directly involved in the reaction.

Explanation:

Spectator ions are ions that are not directly involved in a chemical reaction. They are commonly seen in complete ionic equations and are often taken out to make a net ionic equation because the ions aren't involved in forming the precipitate.

  • Complete ionic equation: Gives all the ions participated in the chemical reaction, even spectator ions.
  • Net ionic equation: Leaves out spectator ions so the equation only shows the ions that formed the precipitate.

For example, this is very useful when dealing with redox reactions because are complicated enough without spectator ions being in the way, so they help focus on those ions that actually form the precipitate.

A solution of methanol and water has a mole fraction of water of 0.312 and a total vapor pressure of 21 torr at 39.9 degrees C.
Elan Coil [88]

Answer:

Explanation:

Given the details, we can say that

Pure methanol is a volatile solvent as the vapour pressure has a high value. This means that methanol - methanol intermolecular forces are weak in comparisson to water - water forces. When having about 30% of water in a methanol mixture, the mixture Pv decreased, showing that it is not a volatile mixture, so then there are strong intermolecular interactions between methanol - water, part of it due to the hydrogen bonds.

What is the pH of <br> 0.000519 M NaOH?
Softa [21]

The pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.

<h3>What is pH of solution?</h3>

The pH of a solution is defined as the logarithm of the reciprocal of the hydrogen ion concentration  [H+] of the given solution.

Concentration of the basic solution, [OH⁻] = 0.000519

pOH = -log[OH⁻]

pOH = -log[0.000519]

pOH = 3.28

<h3>pH of the solution</h3>

pH + pOH = 14

pH = 14 - pOH

pH = 14 - 3.28

pH = 10.72

Thus, the pH of the sodium hydroxide (NaOH) solution at the given concentration of 0.000519 M is determined as 10.72.

Carbon Dioxide in a 34 L container at a pressure of 387 mm Hg is transferred to a container with a pressure of 274 mm Hg. What i
AVprozaik [17]

Answer:

V2= 0.0796m3

Explanation:

We have that for a real gas the following relation is fulfilled:

PV / T = constant

To use this formula I need to pass the pressure of mmHg to KPa and the volume of L to m3, knowing that

 1Kpa = 7.50062mmHg

1L = 0.001m3

So i can say

P1V1/T1 =P2V2/T2

So

V2= P1V1T2/P2T1

V2= 51.60KPa*0.034m3*350k/36.53KPa*211k

finally

V2= 0.0796m3

Why is rain water slightly acidic
viva [34]

Answer:

Explanation:

Natural Rain:

"Normal" rainfall is slightly acidic because of the presence of dissolved carbonic acid. ... The gases of sulfur oxides and nitrogen oxides are chemically converted into sulfuric and nitric acids. The non-metal oxide gases react with water to produce acids (ammonia produces a base).Natural Rain:
