Abiodiesel mixture containing c16h34 and c11h10 was burned in an experimental diesel engine. the orsat analysis of the combustion gases reveal co2=7.38%, co=0.82%, o2=9.76% and the rest n2. determine: 1. the cetane number of the fuel 2. percent air used 3. the specific gravity of the fuel (given the specific gravities; c16h34=0.7751 c11h10=1.025) 4. the partial pressure of water if the dry combustion gases exits at 300c and 2 atm

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.

What must be in balance for temperatures to remain constant?

Which of the following best describes technology a. something created for only scientists to use b. the method of thinking that scientists use. c. the application of engineering to create useful products. c. a scientific idea
