When 150. mL of 0.400 M H+ are mixed with 200. mL of 0.500 M OH-, the final temperature of the solution is 26.5°C. What was the initial temperature of the solution before the reaction occurred? Assume that the solution has a total mass of 350. g and a specific heat capacity of 4.184 J/g°C. The enthalpy of neutralization for the reaction is -62.0 kJ/mol of water produced.

Calculate the change in pH when 46.00 mL of a 0.600 M solution of NaOH is added to 1.00 L of a solution that is 1.00 M in sodium acetate
Radioactive radon gas (222Rn) enters an average building at a rate of 5 picocuries per second per square meter of foundation area. Consider a house with a foundation of 400 square meters and a volume of 1000 cubic meters.
what is the molecular geometry around each central atom: CH2CH2(double bond) C=? C=? Also, for CH3 O CH3 C-O-C C=? O=? C=.
This is a fact that Bromine(Br) is larger than chlorine(Cl) but indication of equilibrium constant suggests that a bromo substituent has a less preference for the equatorial position than chloro substituent? Explain it briefly?
supoose that ammonia, applied toa field as a fertilizer, is washed into a farm pond containing 3.0 x 10^6 L of water. if the pH of this pond is found to be 9.81
Tin carbonate solid is treated with nitric acid to dissolve tin carbonate to give tin nitrate, water and carbon dioxide. a) Write a balanced equation for the reaction.
Analyze the groups bonded to the carbon of interest. Every H contributes +1, and every oxygen contributes -2. An -OH group contributes (-2 + 1 = -1). Ignore carbons bonded to the carbon of interest. The sum of the oxidation states must be zero, si..
