calculate pH of following solution

a) 40ml of 0.050M  Na2CO3 + 50ml of 0.040 M HCl

b)40ml of 0.020M Na3PO4 + 40 ml of 0.040 M HCl

one from me

question 5:

for the ellipse

x2/9 + y2/4 =1  

.let  O be the center and S and S' be the foci. Then  for any point P on the ellipse the value  of PS.PS' .d2 =____ (where d is the distance of O from tangent at P )

no because if they cut each other then at their intersection point their  will be two directions of electric field that is not possible.

answer to q1 is [0,3/2]

since in the interval   , 

so                    

integrating both sides                      

                                                            

therefore ans [0,3/2]                                   (pi/2~1.5)

the apparatus consists of three temperature jacked 1L bulbs  connected by stopcocks .bulb A contains a mixture of H2O (g),CO2(g) ,N2(g)

at  250C and a total pressure of 564 mm Hg.bulb B is empty and is held at temperature  of -700C.bulb C is also empty and is held at

temperature of -1900C . the stopcocks are closed and the volume of lines connecting the bulbs is zero. CO2 sublimes at -780C and N2 

boils at -1960C   .

 

Q. the stopcock  between A and B is opened and the system is allowed  to come to equilibrium .the pressure in A and  B is now 219mm Hg.

what are the compositions are in bulbs A and B.

 

Q both stopcocks are open  and at equilibrium pressure throughout  the system is 33.5mm of Hg. now the compositions in bulbs A,B,C=?

 

Q. number of moles of N2 and CO2 in above system are
