Suppose you live in an alternate universe where a different set of quantum numbers is required to describe the atoms in that universe. The quantum number rules in the alternative universe are:Principal quantum number: n=1,2,3,....Angular momentum quantum number: l=0,2,4.....[2(n-1)]Magnetic quantum number: m(l)=0, +/-1, +/-2How many orbitals are there in the first five electron shells? Sketch an energy level diagram that could be filled in with electrons.
Calculate the heat released when 2.00L of Cl2(g) with a density of 1.88 g/L react with an excess of sodium metal as 25°C and 1 atm to form sodium chloride. [H°f(NaCl) = -411.0 kJ/mol
filtrate be used to transfer the residue when the desired product is solid
Calculate the pH and the percent ionization of butanoic acid in this solution. *I will only award points if a solution is presented. What good does just the answer do for me?
A reaction with a low enthalpy of reaction value is not spontaneous at low temperature but becomes spontaneous at high temperature.
A compound is constituted by mass of 22.6% phosphorus, the rest being chlorine. Given that a volume of 307 mL of the gas has a mass of 1.55 g at 25 °C and 90 kPa, find the molecular formula for this compound
compressed gas cylinder contains 1.00 x 10^3 g of argon gas. The pressure inside the cylinder is 2050 psi at a temperature of 18 C.
at 986°C is 0.63. A rigid cylinder at that temperature contains 1.2 atm of carbon monoxide, 0.20 atm of water vapor, 0.30 atm of carbon dioxide, and 0.27 atm of hydrogen. Is the system at equilibrium?
What is the molecular geometry of Cl2CO?
Silver chloride, often used in silver plating, contains 75.27% Ag.Calculate the mass of silver chloride in grams required to make 6.0 g of silver plating.
What are the percentages of each molecular ion? (List to nearest 1% in order of increasing mass separated by commas, e.g. 55,45.)
These 3 solutions including 2.362 g of Rb2S, 1.635 g of NaClO 4 , and 0.796 g of CuCl 2 , respectively are combined together? now calculate what would be the mass of this precipitae?
After 42 days a 2.0 g sample of phosphorus 32 contain only 0.25 g of the isotopt. what is the half life of the phosphours 32 ?
