Question- Calculate the change in pH when 7.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
Write solution with complete explanation of required steps
A sample is known a carbonate. How can I design an experiment that can allow me to determine the exact identity of the carbonate
Write the expression for the reaction rate in terms of d[NOCl]. c. The concentration of NOCl drops from 0.580 M to 0.238 M in 8.00 min. Calculate the average rate of reaction over this time interval.
Presume that when determining the volume of a pycnometer a student didn't notice there were air bubbles inside the pycnometer when it was filled with water. Explain what effect would this have on the determination of the pycnometer's volume
Explain when a reactant or product not a solid or pure liquid is added to a chemical system at equilibrium, the system should consume the entire newly-added amount to re-attain equilibrium.
Find the structures of Naphthol and phenol shown below and describe (in 2-3 sentences) why phenol is more soluble in water than naphthol?
A particular voltaic cell operates on the reaction below, giving an emf of 0.865 V. Calculate the maximum electrical work generated when 20.0 g of zinc metal is consumed. Zn(s) + CI2(g) ? Zn2+(aq) + 2 Cl ?(aq)
A 10.0-mL sample of a HCl solution has a pH of 2.000. What volume of water must be added to change the pH to 4.000?
Consider 25.0 g of water at 21.7°C that are mixed with 25.0 g of water at 43.3°C in a foam cup calorimeter. The equilibrium temperature reached was 30.4°C. Calculate the calorimeter constant in J/°C.
For each of the pairs of elements below give the formula for the simplest compound to be formed from them and explain the basis of your decision and note if the bond
the temperature of the calorimeter (including its contents) rose from 23.18oC to 27.65oC. What mass, in g, of benzoic acid was burned. here is what i did, 3226/122.13=26.41 delta t =4.474 so 4.474*12.5/26.41 =2.12 is the answer 2.12g
You performed these reactions in an acidic solution(diluting with 0.1MHNO3). This is because iron forms an insoluble hydroxide even when these solutions do not contain excess hydroxide ion (i.e. even in slightly acidic solutions)
How long would it take for 1.50 mol of water at 100.0 0C to be converted completely into steam if heat were added at a constant rate of 15.0 J/s?
