Using a mechanism (arrows that show how H ions move around) write the equation for self-ionization of water and why ammonia is a weak base.
How many grams of N2 are required to react with 2.30 moles of Mg in the following process?
Chlorine can be generated by heating together magnesium hypochlorite and hydrochloric acid. Magnesium chloride and water are also formed.
1.What is the effect of the following on the observed melting point of the compound: a) insoluble purity, such as charcoal; b) incomplete drying of the sample; c) less recrystallization solvent was used than it was needed?
Suggest a reason why the cyclic intermediate in the formation of methyl-e-4-methoxycinnamte from p-anisaldehyde, might have two important groups in a trans relationship
Copper dissolves in nitric acid, producing copper (ll) nitrate. After reaction with sodium hydroxide and heating, copper nitrate changes to copper (ll) oxide. Calculate the percent yield of this process if 1.075 g of copper produced 1.075 g of cop..
Compare the proposed reaction mechanism for the sodiumhypochlorite oxidation of cyclohexanol with that involved in thechromic acid oxidation. Do you notice any similarities?
Compute the amount of heat required to boil 92.1 grams of benzene (C6H6), start from a temperature of 42.5 degrees Celsius.
Explain Net Ionic Equations and Balancing, These are only eight out of a fifty-three question hand out, but with eight answers to reference off of I think I'll be far more successful in my attempts at this.
The mass of a cube of iron is 363 g. Iron has a density of 7.87 g/cm3. What is the mass of a cube of lead that has the same dimensions?
what is the enthalpy change per mole of ethanol combusted? The specific heat capacity of water is 4.184 J/g×K and the molar mass of ethanol is 46.07 g/mol.
Calculate the pH of a solution with the following: 5.12 moles of HCl are placed in a 3.00 L of water 4) Given the acid pKa is 4.76. Calculate the pH of a 0.35M acetic acid solution:
Thus, as long as the concentrations of HA(aq) and A-(aq) are not consumed, the pH change is minimal compared to addition to a non-buffer solution. Why is the buffer most effective when pH = pKa?
