CO2 (g) + 2NH3 (1) → CO(NH2), (s) + H2O(1) This reaction models how urea fertilizer is produced from carbon dioxide and ammonia, with water as a byproduct. This is a chemical engineering process, and a urea factory is shown in this image: Belgvap w eun At the factory, a new engineer combines of 1500 L of carbon dioxide and 1500 g of ammonia (NH3). His goal was to have no excess reagent left over. To his surprise, he miscalculated! One of the reagents ran out first. Help him determine which one ran out first, and also calculate the amount of urea produced. 1) Convert both initial reactant values into moles. 2) Which reagent is the limiting reagent? 3) What mass of urea, CO(NH2)2, is produced? Urea has a molar mass of 60.1 g/mol. Please make sure to show your work.

In our first lab experiment we will be identifying metals by measuring theirdensities and comparing them to known values. Here at NJIT we have a very large and generouslaboratory materials budget, so all sorts of exotic and extremely valuable metals will be providedfor the experiment. Using the values listed below, determine the identity of the metal samples.If the density value determined is not amongst the values below then one of those cheapRutgers samples crept into our stock of metal samples and you should answer “unknown metal”.Note: volume measurements are not very exact. If your density determination is off by 0.1 or0.2 from the known value, that’s probably good enough for an identity. Table in image 4a. You weigh your sample and determine it weighs 71.8 grams. You put the sample into 15.6 mL ofwater and the total volume rises to 22.4 ml. What metal do you have?4b. You weigh your sample and determine it weighs 56.3 grams. You put the sample into 28.9 mL ofwater and the total…

Referring to your best straight line graph, what are the units of the slope?What physical property of steel is the slope of this line related to? Use the graphed data and your best trendline equation to predict the diameters of the three unknown ball bearings.Show your calculations below and report your three results in the data table above with 2 decimal place accuracy. ] 7. How could we improve the accuracy of the largest unknown ball bearing's diameter prediction? can you help me answer all this questions please, ai really appreciated it.

A volume of 250 ml of a 0.05 M solution of a reagent of formula weight (relative molecular mass) 40 was made up, the weighing being done by difference. The standard deviation of each weighing was 0.0001 g. 1 (a) What were the standard deviation and relative standard deviation of the weight of reagent used?
