Xenon hexafluoride (XeF6) reacts with hydrogen gas (H2) to produce xenon gas and hydrogen fluoride gas (HF) according to the following chemical equation. XeF6(s) + 3 H2(g) → Xe(g) + 6 HF(g) If 1.74 moles of H2 is consumed in the chemical reaction above, how many grams of H2 are consumed? For your answer, only type in the numerical value with three significant figures. Do NOT include the unit or the chemical (numbers only).

How many grams of magnesium metal will react completely with 8.3 liters of 5.5 m hcl? show all of the work needed to solve this problem. mg (s) + 2hcl (aq) → mgcl2 (aq) + h2 (g)

Does anyone know a lot about how to: - calculate mass of magnesium metal - calculate the actual yield of magnesium oxide - calculate the theoretical yield of mgo - calculate the percent yield of mgo - determine the percent yield of mgo - determine the average percent yield of mgo i had to do an online lab and its asking these questions but i have no idea where to start or how to be able to find these things. i can post the chart of the data from the lab or if you can tell me exactly how i can find each.

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light
