Give some examples of application of organometallic in electrical industry. Explain how the organometallic are used or involved in electrical industry.
Question- a) What is the mathematical equation that relates absorbance and concentration? Define each symbol. b) How are A and %T related mathematically
A solution is made by combining 500ml of .10M HF with 300ml of .15M NaF. What is the pH of the solution? (Ka=7.2e-4 for HF)
Calculate the pH of the solution when 20.00 mL of 0.10 M CH3CO2H (Ka= 1.76 x 10^-5) has been titrated
A 1004.0 g sample of calcium carbonate that is 95% pure gives 225 L of carbon dioxide at STP when reacted with an excess of hydrochloric acid. What is the density in g/L of the carbon dioxide?
If a 0.10M aqueous weak acid solution has a pH of 2.50 what percentage of the acid is dissociated
MnSO4 is converted to MnO2 in a basic medium as oxygen gas is converted to hyroxide ion. In this case, is the sulfate ion a spectator ion. (NaOH is also present. Is sodium ion also a spectator ion) A. Print the oxidation half-equation B
Why can anhydrous NaOH not be used to dry t-amyl chloride instead of calcium chloride and what side products may be produced
1. Fat has a lot of kcal, and many people are carrying too much weight. Should humans consume fat? If so, what kind (be specific, using the names [not just types] of the fatty acids) and why.
Draw a Lewis structure for the most importance resonance form of each ion, showing formal charges as well as oxidation numbers of the atom (a) AsO43-(b)ClO2-
Problem- Find the ratio of no of Na atoms in 3p excited state to the no. in ground state at 2500 K. the average wavelength of two sodium emission lines is 5892 A.
Which of the possible unknowns for this experiment would give this behavior. Write a balanced equation for the reaction observed between this compound and BaCl2.
The experimental value of nylon 6,10 is 2.160 grams. I need to calculate the theoretical mass of nylon 6,10, in order to find out the percent yield.
