Question- While purifying a carbonyl compound formed by reacting CO2 with a Grignard aryl bromide reagent, I treated my mixture with 5% NaOH and 6 M HCl. What was the purpose of this? Include a balanced chemical equation explaining.
I want you to elucidate the chemistry in this above problem.
If the reaction 2 NO(g) + O2(g) ? 2 NO2(g) is carried out at STP, what is the total pressure? What is the temperature at STP
A gas sample was collected over water at 25.3 0C. The total pressure is determined to be 0.97 atm. What is the partial pressure of the gas that was collected?
What is the pH of a 0.17 M solution of methylamine (CH3NH2, Kb = 4.4 × 10-4) at 25oC
78 mL of 2.5 M phosphoric acid is neutralized with 500 mL of potassium hydroxide. What is the concentration of the base?
a) Gaseous Cl2 in the stratosphere to form gaseous Cl atoms. b) Gaseous CO reacts with gaseous H2 to form liquid methanol, CH3OH. c) Calcium phosphate precipitates upon mixing Ca(NO3)2(aq) and (NH4)3PO4(aq).
Is it possible for the activation energy of a reaction to be negative? Define conclusion and provide a molecular interpretation
2 drops of methyl orange indicator are added to a 25.0 mL sample of strontium hydroxide. A 0.073 M HCl solution (titrant) is dispensed into the solution (analyte). The solution turns from yellow to red after the addition of 29.5 mL.
1.isomerization of cyclopropane to propene is yielding the activation energy for this process is 274 kjmol. by what
determine the total concentration in moll of cl- ions in a solution formed from the reaction of 500ml of 1.0m barium
the value of the equilibrium constant K(pressure) is 0.2230. If a sealed vessel contains an initial reaction mixture of N2 = 0.0100M, H2= 0.0200M and N2H2= .000150M what will N2H2(M) be when equilibrium in reached.
the vapor pressure of pure water at 50.0 degc is 92.5 mm hg. calculate the ideal partial pressure of water at this
To determine the enthalpy change for this reaction, 0.158 g of Mg metal is combined with enough HCl to make 100.0 mL of solution in a coffee-cup calorimeter of negligible heat capacity.
