When nitroglycerin explodes it produces nitrogen, oxygen and water and carbon dioxide. If the heat of reaction is -5692 kj/mol how much heats released when 4.5 g of the explosive reacts? Show balance reaction in
Explain why the atomic mass of an atom is a decimal number and how that value was determined before being placed on the periodic table.
A 0.150- M solution of chloroacetic acid (HC2H2ClO2) has a pH of 1.86. What is the value of Ka for this acid and the percent ionization?
A voltaic cell is based on the reaction Sn(s)+ I2 (s) --> Sn^2+ (aq)+ 2I^- (aq). Under standard conditions, what is the maximum electrical work, in joules, that the cell can accomplish if 70.0 g of Sn is consumed?
Calculate the number of moles of H2O formed when 0.200 mole of Ba(OH)2 is treated with 0.500 mol of HClO3 according to the chemical reaction shown below.
Calculate the average speed of a gas that has a molar mass of 2.08 × 10-2 kg /?mol at a temperature of 22°C. The value for the gas constant, R, is 8.314 J /?mol K.
Under standard-state conditions, what spontaneous reaction will occur in aqeuous solution among the ions
The ketone used was cyclopentanone and the aldehyde used was benzaldehyde. First cyclopentanone was dissolved in 95% ethanol. Then benzaldehyde was added along with NaOH to the mixure. The solution was then mixed creating the aldol condensation pr..
