In a 35.0 L tank of N2O3 at STP, how many molecules are there?​
likoan [24]

Answer:

9.40x10^{23}molecules

Explanation:

Hello!

In this case, since we are given the volume of N2O3 and pressure and temperature for the STP (1.00 atm and 273.15 K), we can compute the moles, considering the ideal gas equation as shown below:

PV=nRT\\\\n=\frac{PV}{RT} \\\\n=\frac{1atm*35L}{0.08206\frac{atm*L}{mol*K}*273.15K}\\\\n=1.56mol

Now, by using the Avogadro's number it is possible to compute the molecules of this case in 1.56 moles:

molecules=1.56mol*\frac{6.022x10^{23}}{1mol} =9.40x10^{23}molecules

Best regards!

For each pair of salts, determine which of the salts, if any, would be expected to be more soluble in acidic solution than in pu
gogolik [260]

Answer:

AgNO2

Explanation:

The question asks to know which of these two insoluble salts is expected to be more soluble in acidic solution than in pure water.

To answer this question specifically, we need to know if the anions contained in the insoluble salt is a conjugate of a weak acid or that of a weak base.

Generally, the solubility of insoluble salts that contain anions which are conjugates of weak acids increases in the presence of an acidic solution than in water. While, the solubility of insoluble salts that contain anions which are conjugates of strong acids decreases in the presence of an acidic solution.

Having said this, AgNO2 contains NO2 which is the conjugate base of the Trioxonitrate iii acid which is a weak acid. Hence, it is expected to be stronger in acidic solution than in water.
