Chemical and metallurgical engineers usually find themselves as engineers for certain process industries. sketch a labelled process flow chart for any product/metal production. (15) note for question 1a): • the flow chart should be your own work and not a copy and paste diagram. any product process is acceptable except the one for pulp and paper industry process flow chart (can be a product process or manufacturing) • start from raw material to the final product (assure that the flow structure is sequential) • include input resources, conversion steps, output and recycle stream (could be waste streams as well) where required, include electricity and other energy flows and also indicate where it is not required b) explain the importance of the ability to identify and draw/sketching process flow charts (2) c) describe the significance of material and energy balances to process engineering

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.

Drag each label to the correct location on the chart. classify each reaction as endothermic or exothermic.
