Which of the following chlorides is the most ionic? Please explain a) CH2Cl2 b) SiCl4 c) SCl2 d) PbCl2 Please expalin
Making plastic drinking bottles for bottled water requires about 58 million barrels of oils per year (2007). In 2007, 300 million people averaged 114 L of bottled water per person. The average cost of 0.6 L was $1.00. The average charge for tap wa..
Ammonium chloride is used as an electrolyte in dry cells. Which of the following statement about a 0.10 M solution of NH4CL, is correct?
what measuring device would you use to measure the volume under each of the conditions described below? in some cases
what will be the final temperature. The specific heats of ice and water are 2.09 and 4.184 J/g.°C, respectively. The heat of fusion for water is 334 J/g.
the rate constants of some reactions double with every 10 degree rise in temperature. Assume that a reaction takes place at 305K and 315 K. What must the activation energy be for the rate constant to double as described?
If 5.36 103 kg each of NH3, O2, and CH4 are reacted, what mass of HCN and of H2O will be produced, assuming 100% yield?
The C^14 decay rate for the sample of glue was found to be 5.60d/min/g. What is the approximate age of the glue. Disintegration of C^14 is a first order process with a rate constant 1.209*10^-4 year^-1.
calculate the volume of O2 the bottle could deliver to a climber at an altitude where the temp is -38 C and the atmospheric pressure is 0.40 atm.
Data for the decomposition of hydrogen peroxide at some set temperature T is include below. The rate law depends only on the concentration of H2O2.
The ionic structure of NH4Cl follows the radius-ratio rule. The ionic radii of NH4+ and Cl are 143 pm and 181 pm, respectively. Use the radius-ratio rule to predict the ionic structure. Describe the properties of the unit cell.
Sodium carbonate was used to precipitate silver from a solution. 6.00 grams of silver carbonate were recovered 1.500L of solution. What was the concentration in ppm of silver ions in the original solution?
Really confused on calculating/finding the half-equivalence point in a titration curve. This was a lab experiment done in my chem lab. We added 0.0750 M NaOH to acetic acid (pipet 10.00mL of ~0.1M HCH3CO2 into the beaker and add 40mL of DI water).
