A piece of metal weighing 5.10 grams at a temperature of48.6oC was placed in a calorimeter into 20.00 mL ofwater at 22.1oC, and the final equilibrium temperature was found to be 29.2oC. What is the specific heat of the metal?
how many grams of sodium formate nacho2 must be added to 750.0ml of .250 m of formic acid hcho2 to obtain a buffer with
Explain the fact that KOH is much more soluble in liquid ammonia containing a little water than in pure liquid ammonia.
Sodium metal reacts with water to produce hydrogen gas and sodium hydroxide according to the chemical equation shown below. When 0.025 mol of Na is added to 100.00 g of water, the temperature of the resulting solution rises
Potassium nitrate decomposes on heating, producing potassium oxide and gaseous nitrogen and oxygen: 4KNO3(s)→ 2K2O(s) + 2N2(g) + 5O2(g)
How many moles of hydrogen are produced by the unbalanced reaction below when 0.195 moles of magnesium and 0.102 moles of water are allowed to react? Mg (s) + H20 (l) > Mg(OH)2 (s) + H2 (g)
Ethanol CH3CH2OH(l) can be formed from a reaction between ethylene gas C2H4(g) and water vapor. It is unclear if the C-C in ethylene gas is a single, double, or triple bond.
Values of the rate constant for the decomposition of N2O5 at four different temperatures are as follows: Determine the activation energy (I got this step right, Ea = 101.15 kJ/mole)
A solution is 0.034M in Na2SO4 and 0.035M in Na2CrO4. Solid Pb(NO3)2 is added without changing the volume of the solution. A. Which salt will precipitate first?
A solution of phosphoric acid was made by dissolving 10 g of H3PO4 in 100 ml of water. The resulting volume was 104 mL. Calculate the density, mole fraction, molarity, and molality of the solution. Assume water has a density of 1.00 g/cm3
Explain the following: a.) The cycloheptatrienyl anion is antiaromatic, whereas the cyclononatetraenyl anion is planar (in spite of the angle stain involved) and appears to be aromatic. b.) Although
We performed an extraction using benzoic acid, 2-naphthol and 1,4-dimethoxybenzene. What is the chemical reaction for the protonation of 2-naphthol using NaOH and the reprotonation of 2-naphthol using HCl
For each of the following electronic transitions in the hydrogen atom, calculate the energy, frequency, and wavelength of the associated radiation, and determine whether the radiation is emitted or absorbed during the transition:
