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 Y 2 volumes compound I 2 volumes gas X + 1 volume gas Y 2 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.
Calculate the average density of a single Al-27 atom by assuming that it is a sphere with a radius of 0.143 nm. The masses of a proton, electron, and neutron are 1.67261024g,9.10941028g, and 1.67491024g, respectively. The volume of a sphere is 4r3/3, where r is its radius. Express the answer in grams per cubic centimeter. The density of aluminum is found experimentally to be 2.70 g/cm3. What does that suggest about the packing of aluminum atoms in the metal?
Choose the correct answer choice. Given the statement below, which choice best accounts for these observations?
Suppose you synthesized copper nanoparticles and found the average particle diameter to be 6.2 nm. How many copper atoms would you expect to find in the particle? One approach: assume the particle is spherical. In all cases, assume the particle has 24 Cu atoms across the diameter (the radius of each Cu atom is 128 pm) What fraction of the atoms would be surface atoms.
Show how Lavoisier's conservation of matter can be explained on the basis of the assumptions of the Atomic Theory. Would you classify the conservation of matter as a law or as an empirical generalization....?
A new compound has the empirical formula GaCl2. Thissurprises some chemists who, based on the position of gallium in the periodic table, expect a chloride of gallium to have the formula GaCl3 or possibly GaCl. They suggest that the “GaCl2” is really Ga[GaCl4], in which the bracketed group behaves as a unit with a -1 charge. Suggest experiments to test this hypothesis
Give answer of the question and also provide explaination of true and false statements!
Dinitrogen monoxide (N₂O; nitrous oxide) is a greenhousegas that enters the atmosphere principally from natural fertilize rbreakdown. Some studies have shown that the isotope ratios of ¹⁵N to ¹⁴N and of ¹⁸O to ¹⁶O in N₂O depend on the source, which can thus be determined by measuring the relative abundance ofmolecular masses in a sample of N₂O.(a) What different molecular masses are possible for N₂O?(b) The percent abundance of ¹⁴N is 99.6%, and that of ¹⁶O is 99.8%. Which molecular mass of N₂O is least common, andwhich is most common?
