Give some examples of the types of hazardous chemicals, specifically oxidizers, stored in homes (such as those stored under counters and sinks, in garages/basements and in pump houses/sheds). Discuss the following:
A) What problems and dangerous situations can result from the improper storage and use (i.e., mixing them together, etc.) of these chemicals? Describe potential hazardous material interactions.
B) What government agency and statutes/regulation(s) govern for the labeling and registration of these hazardous household products?
Toluene (C7H8) and nitric acid (HNO3) are used in the production of trinitrotoluene (TNT, C7H5N3O6) an explosive. C7H8 + HNO3 --> C7H5N3O6 + H2O (not blanced)
determine the exact formula of this compound. When 4.37x10^-4 moles of this complex is dissolved into 425.0 mL of water, you find that 17.49 mL of 0.1000 M HCl is needed to reach a titration endpoint.
Determine the percent by mass of all elements in the compound sodium carbonate decahydrate better known as washing soda.
5.0 mL of 12 M NH3 is added to 500 mL of 0.050 AgNO3. What concentration of silver ion will exist after equilibrium is established. [Kf for Ag(NO3)2 is 1.5 x 10^7]
Assume that all of the atoms fit together next to each other like placing tennis balls in a cardboard box. The second layer directly on top of the lower layer.
sodium hydroxide is extremely soluble in water. At a certain temperature, a saturated solution contains 551g of NaOH (s) per liter of solution. Calculate the molarity of this saturated NaOH (aq) solution.
The rate constant (k) for a reaction was measured as a function of temperature. A plot of ln k versus 1/T (in K) is linear and has a slope of -6542 K. Calculate the activation energy for the reaction.
What is the rate of the reaction if the concentration of CH3Br is doubled. B. What is the rate of the reaction if the concentration of NaOH is halved
If 348 grams of K2SO4 (molar mass 174 grams) is dissolved in enough water to make 500 milliliters of solution, what are the concentrations of the potassium and sulfate ions.
If metallic copper forms on a strip of nickel dipped in 1M CuSO4, what conclusions can be reached about the relative strengths of Ni 2+ (aq) and/vs Cu 2+ (aq) as oxidizers
At 63.5C the vapor pressure ofH2O is 175 torr, and that of ethanol,C2H5OH, is 400 torr. A solution is madeby mixing equal masses of H2O andC2H5OH.
A solution that contains 55.0 g of ascorbic acid (Vitamin C) in 250. g of water freezes at -2.34°C. Calculate the molar mass (in units of g/mol) of the solute. Kf of water is 1.86°C/m.
