NO + 3Cu2++ 2H2O -----> 3Cu+ + NO3-+ 4H+
In the above redox reaction, use oxidation numbers to identify the element oxidized, the element reduced, the oxidizing agent and the reducing agent.
The pH of a saturated solution of nickel hydroxide, Ni(OH)2, is 8.83. Calculate the Ksp for nickel hydroxide.
In a clock reaction 20.0mL of 0.200M KI, 20.0mL of 0.100M (NH4)2S2O8 and 10.0mL of 0.00500M Na2S2O3 were mixed in the presence of a starch solution indicator. The solution turned blue in 63.9 seconds.
Potassium hydrogen phthalate is a solid, monoprotic acid frequently used in the laboratory to standardize strong base solutions. It has the unwieldy formula of KHC8H4O4. This is often written in shorthand notation as KHP.
Question- Dimercaprol (HSCH2CHSHCH2OH) was developed during WW1 as an antidote to arsenic based poison gas and is used today to treat heavy metal poisoning. It binds the toxic element and carries it out of the body.
Why, in a primitive cubic cell, do anions sit on the lattice points while the cation fills the lattice hole in the center a. Because it is favorable for anions to be as close to one another as possible.
1. a calculate thespeed that a gas phase oxygen molecule would have if it had thesame energy of an infrared photon
Copper is highly sensitive to oxidation by molecular oxygen. Higher oxidation states of Cu do not catalyze diazocoupling reactions. Define oxidation (loss of electrons) and define a redox half reaction for the oxidation of CuI by O2
A molecule of unknown structure has a molecular formula of C9H8O2. In the infrared spectrum there are absorptions at 1761, 1145, and 761 cm-1. In the 13C NMR spectrum there are absorptions at. 168.4, 152.0, 128.2, 128.0, 124.3, 122.8, 116.8, 29.1 ..
The total phosphate concentration is 0.001 M. No other weak acids or bases are present. How many millimeters of 0.5 M H2SO4 are needed to decrease the pH of 1 liter of this water to 6.0
let's pretend a certain sterling silver ring has a mass of 31.25g. silver has 93%. determine the mass of silver found in the ring.
This reaction is a catalytic hydrogenation that only partially reduces an alkyne. Consider whether the hydrogenation
When 33.5 mL of 0.580 M H2SO4 is added to 33.5 mL of 1.16 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate ?H of this reaction
