Define complete precipitation​
ch4aika [34]

<u>Answer</u>:

A precipitation is said to be complete precipitation when no further precipitate can be formed in the process.

<u>Explanation</u>:

Precipitation is the reaction of creating solid from the solution. In precipitation reactions, insoluble salts are formed when two solutions containing soluble salts are combined.

These two solutions contain different salts and have either cation or anion pairing. This reaction helps in the determination of ions in a solution. The solubility table is being used to predict the precipitation reaction. It occurs in solid when one solid’s concentration is above solubility.

Please help with #2 and #3
Vaselesa [24]

Answer:

2. V_2=17L

3. V=82.9L

Explanation:

Hello there!

2. In this case, we can evidence the problem by which volume and temperature are involved, so the Charles' law is applied to:

\frac{V_2}{T_2}=\frac{V_1}{T_1}

Thus, considering the temperatures in kelvins and solving for the final volume, V2, we obtain:

V_2=\frac{V_1T_2}{T_1}

Therefore, we plug in the given data to obtain:

V_2=\frac{18.2L(22+273)K}{(45+273)K} \\\\V_2=17L

3. In this case, it is possible to realize that the 3.7 moles of neon gas are at 273 K and 1 atm according to the STP conditions; in such a way, considering the ideal gas law (PV=nRT), we can solve for the volume as shown below:

V=\frac{nRT}{P}

Therefore, we plug in the data to obtain:

V=\frac{3.7mol*0.08206\frac{atm*L}{mol*K}*273.15K}{1atm}\\\\V=82.9L

Best regards!
