- You have two distinct gaseous compounds made from element X and element Y. The mass percents are as follows: Compound I: 30.43% X, 69.57% Y Compound II: 63.64% X, 36.36% Y In their natural standard states, element X and element Y exist as gases. (Monatomic? Diatomic? Triatomic? That is for you to determine.) When you react gas X with gas Y to make the products, you get the following data (all at the same pressure and temperature): 1. volume gas X + 2 volumes gas Y2 volumes compound I 2. volumes gas X + 1 volume gas Y2 volumes compound II Assume the simplest possible formulas for reactants and products in the chemical equations above. Then, determine the relative atomic masses of element X and element Y.Hydrogen gas is prepared in a lab experiment. In this experiment, 18.00 g of aluminum metal are mixed with 25 mL of HCl (d=1.025g/cm3). After the experiment, there are 12.00 g of aluminum and 30.95 g of a solution made up of water, aluminum ions, and chloride ions. Assuming no loss of products, how many liters of H2 gas are obtained? The density of hydrogen gas at the temperature and pressure of the experiment is 0.0824 g/L.58 Magnesium will burn in air to form both Mg3N2 and MgO. What mass of each product would be found if burning a 3.11-g sample of magnesium to completion produces a combined total of 5.09 g of the two products?

TripAdvisor 33 of 40 I Review | Constants | Periodic Table Learning Goal: To become familiar with the concept and calculations of specific heat. Part A Specific heat (which can be represented as SH, Cs, sp. ht., or a number of other possibilities) is defined as the amount of energy needed to raise the temperature of 1 g of a substance by 1 °C. For example, 0.0920 cal is enough energy to raise 1 g of copper from 21.0 °C to 22.0 °C. Therefore, the specific heat of copper is 0.0920 cal/(g - °C). How much heat energy is required to raise the temperature of 0.360 kg of copper from 23.0 °C to 60.0 °C? The specific heat of copper is 0.0920 cal/(g- °C). Express your answer with the appropriate units. > View Available Hint(s) Using SH for specific heat, the formula for calculating specific heat is HA Value Units heat heat = SH = massxAT P…

For example, CHCIBII is chiral, but CCl,BrI is achiral because some of the bonded groups are the same. If a chiral carbon atom is present, then that molecule has a non-superimposable mirror image called an enantiomer.
