Ionic Radii of Cations Part A Rank the following ions in order of decreasing radius: Rb^+, K^+, Li^+, Cs^+, and Na^+. Use the periodic table as necessary. Rank from largest to smallest radius. To rank items as equivalent, overlap them. Part B Rank the following items in order of decreasing radius: Na, Na^+, and Na^-. Rank from largest to smallest radius
Light travels extremely rapidly (c = 3.00×108 ). Suppose you had to travel 20 miles to work every day. If you traveled at the speed of light for the entire trip, how long would it take you to get to work (in seconds)? [1 mile = 1.61]
CaO + C --> CaC2 + CO2 [unbalanced] If 244 g of CaO is combined with 318 g C, how many grams of CO2 could be produced if the reaction goes to completion
Exactly 10.2 mL of water at 31.0 degrees celsius are added to a hot iron skillet. All of the water is converted into steam at 100 celsius. the mass of the pan is 1.05kg and the molar heat capacity of iron is 25.19 J/(molXC).
Methanol (CH3OH) can be manufactured by the reaction of gaseous carbon monoxide and hydrogen. Suppose 68.5 kg of gaseous carbon monoxide is reacted with 8.60 kg of gaseous hydrogen. If 37.5 kg of methanol is actually produced, what is the percent ..
A Pb-Sn alloy containing 40 wt% Sn is cooled from the liquid state to room temperature. How much of each phase is present in the material at room temperature. Sketch the expected microstructure.
What is the volume of 135 mL of oxygen gas at 113°C and 870. mm Hg if the conditions are adjusted to STP? Assume the amount of gas is held constant.
a solid with an irregular shape and a mass of 11.33 g is added to a graduated cylinder filled with water
The internuclear distance in NaCl(g) is 2.3606 angstrom, whereas in NaCl(s) the shortest Na-Cl distance is 2.814 angstrom. Explain why this should be so when the binding energy is larger in the crystal.
What mass of sodium nitrate (in g) is required to make 2.50L of a 0.150M solution of sodium nitrate
The temperature of a 35.2 g sample of iron increases from 23.7 °C to 29.5 °C. If the specific heat of iron is 0.450 J/g-K, how many joules of heat are absorbed?
C6H5OH(s) + 7O2(g) --> 6CO2(g) + 3H2O(g) A 2.000 gram sample of pure phenol, C6H5OH(s), is completely burned according to the equation above.
The Born-Haber cycle is a series of steps that represent the formation of an ionic compound from a metal and a nonmetal. For example, the steps in a Born-Haber cycle for the formation of NaCl(s) consist of sublimation of the metal Na atom (?Hsubl-..
