Under certain conditions, water can be separated into oxygen and hydrogen gases according to the equation 2H20 2H2 +O In a lab, 112g of hydrogen gas and 888g of oxygen gas were collected. Student A says that the amount of water to start cannot be determined, but Student B says that the water must have been 1000g. Who is correct? O Student A, because the water was not measured to start with. O Neither are correct. It would have been 1112g, because there are 2 H2 to 1 02. O Neither are correct. It was 2000g because the equation shows 2H20. O Student B, because of the law of conservation of matter.

My Chemistry professor was going over conversions from moles today and put the question up of how many atoms of carbon are in 500mg of C6H8O6.As far as I can tell, my dimensional analysis is correct by converting mg to g, then to mol of C6H8O6 to 6 mol of C then multiplying by Na yet my answer was incorrect by getting 1.7X1021

The chemical formula for hydrogen fluoride is HF. A chemist measured the amount of hydrogen fluoride produced during an experiment. She finds that 119. g of hydrogen fluoride is produced. Calculate the number of moles of hydrogen fluoride produced. Round your answer to 3 significant digits.
Archimedes, a famous Greek scientist, was given a problem by King Hieron II of Syracuse (Sicily). The king suspected that his crown, which was supposed to be made of pure gold, contained some silver alloy, and he asked Archimedes to prove or disprove his suspicion. (It turned out that the crown did not contain silver.) How would you experimentally determined whether or not the crown was pure gold? (Hint: The method came to Archimedes when getting into a full bathtub. See the footnote in Experiment 22 for Archimedes’ solution.)

A student synthesizes tin oxide to create a compound with generic formula SnxOy. She does this by combining 30.80 g of tin and when the tin oxide product is produced, the total mass of the product is 39.10 g. Consider the starting mass of the tin (Sn) and the ending mass of the SnxOy product. To find the mass of oxygen in the product, you would _____ A) add the mass of tin from the mass of the product. B) subtract the mass of tin from the mass of the product. C) multiply the mass of tin from the mass of the product. D) divide the mass of tin from the mass of the product.
