I'm very confused! In the titration, the student used 25cm³ of sodium hydroxide. This volume reacted with 20cm³ of 0.1mol/dm³ of a sulphuric acid solution. Calculate the concentration in mol/dm³ of the sodium hydroxide solution.

the answer is a. co2, this would be colder than the : )

explanation:

cock topography

the study of the surface of a large voluptuous cock.

look at that sorostitute right she's a cock topographer!

what classes are you taking this

cock topography!

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
