Thomson used to measure the of a cathode ray particle. Thomson's experiments are important because they showed that the is clearly composed of. The Milikan experiment is important because it determined the of an . Using Thomson's and Milikan's the of an was determined. Rutherford's experiment is important because it clearly demonstrated that the is mostly . Rutherford's results also showed that the most of the atom's is located in the which has a very . use this vocabulary to fill them out. charge a vacuum small volume atom mass nucleus angle of deflection oil drop mass- to- charge ratio smaller particles protons electron magnetic and electric fields gold foil neutrons empty space
An aqueous solution of CaCl2 has a vapor pressure of 83.0mmHg at 50 C . The vapor pressure of pure water at this temperature is 92.6mmHg .
A gas mixture contains 1.25 g N2 and 0.85 g O2 in a 1.55-L container at 18 °C. Calculate the mole fraction and partial pressure of each component in the gas mixture.
Find what is the initial concentration of the chlorine before dilution - unknown concentrated chlorine
Mesitylene is a compound consisting only of C and H. If you burn 0.115 g of the compound, and find that it produces 0.379 g of CO2 and 0.1035 g of H2O.
If 4.10 mol calcium carbide (CaC2) reacts with an excess of water, how many moles of acetylene (C2H2) will be produced?
A lime-soda softening plant treats a flow of 150 MGD, and the water has 86 mg/l CO2. The commercial grade of quicklime has a purity of 85% and the soda ash has a purity of 95%.
The concentration of Mg2+ in seawater is 0.052 M. At what pH will 72% of the Mg2 be precipitated as the hydroxide salt? [Ksp for Mg(OH)2 = 8.9 multiplied by 10-12.]
why we call benzene phenyl and not benzyle when one hydrogen is removed because in case of alkanes we name them alkyl on the removal of one hydrogen atom.
A graduated cylinder contains 25.0 of water. What is the new water level after 34.2 of silver metal with a density of 10.5 is submerged in the water.
Explain why it is preferable to take the geometric mean rather than the arithmetic mean when defining mean activity
compute the enthalpy change, (Delta H), for this reaction per mole of A. suppose that the specific heat =[4.18J/(g*Degrees C) and density=1.00(g/mL)?
How much energy (in kilojoules) is required to convert 285 ml of diethyl ether at its boiling point from liquid to vapor if its density is 0.7138 ?
