What is the molar mass of B,(Croa)g? a. 186 g/mol
b. 369 g/mol
C. 232 g/mol
d. 250 g/mol

b) mutualism

hope this : )

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.

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.
