When copper metal is affed to silver nitrate in solution, silver metal and copper (II) nitrate are produced. Use the balanced equation to answer the question. How many grams of silver are produced from 4.00 moles of copper?​

gasoline is a mixture. it contains several different kinds of compounds that can be present in a variety of ratios.

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.
