To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:

HI

HI + H2O ---> H+ + I-

It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic. 

KBr

KBr + H2O ----> HBr + KOH

The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic. 

LiOH

LiOH + H2O ----> Li+ + OH-

It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.

Which describes the volume of 1 mol of gas at standard temperature and pressure?
densk [106]

Answer:

B) The volume is the same for any gas.

Explanation:

Considering the ideal gas equation as:-

PV=nRT

where,  

P is the pressure

V is the volume

n is the number of moles

T is the temperature  

R is Gas constant having value = 8.314 J/ K mol

At STP,  

Pressure = 1 atm  

Temperature = 273.15 K

So, applying the values we get that 1 mole of any gas occupies a volume of 22.4 L

Thus, correct option is:- B) The volume is the same for any gas.
