Write a reaction showing the reduction (hydrogenation) of 1-hexene to hexane. ( use structures for the compounds). Write a reaction showing the bromination (halogenation) of 1-pentene.
Substance A has a greater molar mass then substance B. Both are nonelectrolytes. If 50 g of substance A are dissolved in 250 g of water in one beaker
The solubility product constant (Ksp) for the dissolution of CaF2 as represented by the chemical equation is 3.4 x 10-11. CaF2 (s) Ca2+ (aq) + 2 F- (aq) Calculate the molarity (M) of Ca2+ in a saturated solution of CaF2
the drops in temperature is measured by 113 degreed celsius when a 55 g sample of a certain metal and it loses heat of
Calculate the quantity of energy produced per mole of -235 (atomic mass = 235.043922 ) for the neutron-induced fission of -235 to produce -137 (atomic mass = 136.9253 ) and -97 (atomic mass = 96.910950 ).
In an experiment to analyze mixture of sodium carbonate, sodium bicarbonate, and an inert component. 10.00ml of 0.100M HCl were used to titrate 0.300g of the sample using phenolphthalein as the indicator. Calculate the number of moles and the mass..
The freezing point for t-butanol is 25.50 degrees C and kf is 9.1 degrees C/m. Usually t-butanol absorbs water on exposure to the air. If the freezing point of a 10.0 g sample of t-butanol is measured as 24.59 degrees C, how many grams of water ar..
What are the concentrations of HSO4-, SO42-, and H+ in a 0.255 M KHSO4 solution? (Hint: H2SO4 is a strong acid; Ka for HSO4- = 1.3 10-2.)
according to the ideal gas law a 10.0 mol sample of methane gas in a 0.815 l container at 503 k should exert a pressure
