A student needs to produce 19.09 grams of nitrogen gas (N2) for a lab experiment. How many grams of ammonia (NH3) will be required to produce this amount of nitrogen? Round your answer to the nearest 0.01 and remember to include units and substance! NH3 --> N2 + H2
A student needs to produce 27.42 grams of nitrogen gas (N2) for a lab experiment. How many grams of ammonia (NH3) will be required to produce this amount of nitrogen? Round your answer to the nearest 0.01 and remember to include units and substance! NH3 --> N2 + H2
Platinum is a precious metal that is used as a catalyst for many important industrial reactions. Platinum can be purified by reacting platinum(IV) bromide solution with aluminium metal. To test this purification process, a student reacted 14.6 kg of aluminium metal with excess platinum(IV) bromide solution. After the reaction was complete, the student had extracted 75.4 kg of platinum metal. From this data, calculate the percent error of this experiment. Hint: Write a balanced chemical reaction equation and calculate the theoretical yield of platinum first. Do not show your work in the space provided. Record only your final answer with the correct number of significant digits and the proper units. Answer: Evaluate your calculated percent error, is this an acceptable percent error?
You are a researcher in a geochemistry laboratory. A colleague brought to you a new mineral that you have never seen before. You need to identify all of the elements and their quantities in this mineral. You turn the mineral into a powder and put the mineral into multiple scientific machines to determine what it is made of. Your sample contained the following elements and amounts. • 160 grams of oxygen 120 grams of silicon • • 80 grams of aluminum . 16 grams of magnesium 32 grams of calcium. . 4 grams of uranium. Determine the mass percent of the different components in your soil sample. • 29. Oxygen 30. Silicon 31. Aluminum 32. Magnesium 33. Calcium 34. Uranium
When heated, NaOH decomposes according to the following equation. If all of the water is produced as water vapor, what is the expected mass loss for a 5.51 gram sample of NaOH? Report your answer with three significant figures. 2 NaOH (s) → Na2O (s) + H2O (g)
It would be really hard to measure the mass of the foam explosion. How does knowing the amount of liquid they started with help predict how much foam there is? (a) The mass of the foam should be twice as much as the liquid they started with (b) the mass of the foam should be equal to the mass of the individual elements that were formed (c) the mass of the foam should be half the mass of the liquid they started with (d) the mass of the foam should be the same as the mass of the liquid they started with
