Write and balance the chemical equation for the reaction between solid calcium bicarbonate (also called calcium hydrogen carbonate) and aqueous acetic acid to form aqueous calcium acetate, water, and gaseous carbon dioxide. Include all physical states.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

the answer your looking for is c).

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.
