Reducing 4.8 grams of Fe_(2)O_(3) with CO yields 3,648 grams of solid A. And gas B a. Calculate the mass % TP of each substance in A. (assuming iron oxide is reduced only to metallic iron)
b. Let B absorb into 400ml dd of NaOH0.2M calculate the CM of the solution obtained after the reaction. (Assume the volume dd is not hilly)
C. Let CR A react with excess dilute HNO_(3) to yield NO and dd D. Concentrate dd D to yield 25.32 g of solid E. Calculate the volume of NO and CT of E. Gas measurement ptc

It is important to wear proper protective equipment in lab even when not actively performing experiments because accidents can affect any researcher, even one not working on an experiment. select the best answer from the choices provided

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.
