Chlorine reacts with water to produce hydrochloric acid. Suppose 2.5 kg of chlorine were added to an olympic-sized swimming pool. How many grams of calcium carbonate would be needed to neutralize all of the hydrochloric acid that might be produced by this amount of chlorine?
The reaction of chlorine and water is as the following: Cl2 + H2O --> HCl + HClO
To find the of X-281, you prepare a 0.086 test solution of X-281. The pH of the solution is determined to be 2.70. What is the of X-281
Calculate the density of air at the experimental conditons identified in part A C) Calculate the mass of air in the flask before the liquid was added.
The use of phenols such as tert-butylcatechol as free-radical scavengers is based on the fact that phenolic hydrogens are readily abstracted by radicals
If the average speed of an oxygen molecule is 4.43 multiplied by 104 cm/s at 25°C, what is the average speed of a CO2 molecule at the same temperature?
A 1.00 g sample of enriched water, a mixture of H2O and D2O, reacted completely with Cl2 to give a mixture of HCl and DCl. The HCl and DCl were then dissolved in pure H2O to make a 1.00 L solution
A 1-L flask is filled with 1.30 g of argon at 25 degrees Celsius. A sample of ethane vapor is added to the same flask until the total pressure is 1.05 atm. What is the partial pressure of argon in the flask?
Eventually, the water becomes saturated with respect to NaCl. Write a balanced chemical reaction illustrating the precipitation of NaCl and explain saturation
Suppose that the microwave radiation has a wavelength of 11.6cm . How many photons are required to heat 225 mL of coffee from 25.0 C to 62.0C ? Assume that the coffee has the same density, 0.997 g/mL, and specific heat capacity, 4.184 , as water o..
What is the molarity of a HCl solution if the reaction of 223 mL HCl with excess CaCO3 produces 10.7 L CO2 gas at 714 mmHg and 36°C?
Tell what type of chemical reaction is represented by the following chemical equation.
30.0 mL of pure water at 280. K is mixed with 50.0 mL of pure water at 348 K. What is the final temperature of the mixture? Ignore significant figures for this problem.
