Air at 20°c blows over a hot steel (1 %c) plate75 by 50 cm and 2 cm thick maintained at 250°c. the convection heat transfer coefficient is 25 w/m2. °c. a 300 w is lost from the plate surface by radiation. calculate the inside plate temperature.

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.
