A titration experiment is set up to use 0.235M bleach (NaOCl) to analyze CrO2-. If 50.0mL of the CrO2-(aq) solution required 37.75mL of bleach to react to completion, what would you calculate as the molarity of the CrO2- solution?2ClO-(aq) + CrO2-(aq) ----> 2Cl-(aq) + CrO42-(aq)
what mass of neon gas should be introduced into an evacuated 0.55 L to produce a pressure of 80 kPa at 30 degrees celsus
if 6.73 g of NaCo3 is dissolved in enough water to make 250. mL of solution what is the molarity of the sodium carbonate ?
Climbers sometimes develop Acute Mountain Sickness (AMS) when ascending too rapidly without allowing their bodies time to acclimate to the lower oxygen concentrations in air at high elevations.
The data for the trickling filter is the following: recirculation ratio = 1.5; diameter = 25 m; depth = 2 m. Determine the hydraulic load (m3/dm2) and the treatment efficiency of the trickling filter.
An ideal gas is allowed to expand from 8.40L to 12.6L at constant temperature. By what factor does the volume increase. The pressure will increase by same factor
Determine the adiabatic flame temperature (C). Assume product temperatures of 1500K and 3000K, and then linearly interpolate.
Based on the data for step 2 of the experiment, predict what would happen if you performed step 3 of the experiment (how many sets of three drops of each of the HCl and NaOH would be needed until the buffering capacity is lost for the two solution..
