A soil analysis was done for the exchangeable cations in the soil and the results were as follows:Ca = 1.8 g/kg (atomic wt. Calcium is 40 g/mol)Mg = 3.25 cmolK = 3 cmolNa = 0.230 g/kg (atomic wt. of Na is 23 g/mol)H = 9 ...
Determine the percent yield(with respect to CO2 and CH4) of the reaction if 1.25g of CO2 was formed by reacting 2.50g of CH4(g) with excess O2 in the reaction: CH4(G) +O2(g) ---->CO2(g) +H2O(g).
Using the following data, calculate the pressure of 100.0mol of CO(g) in a 40.0L container at 25 degrees Celcius using both the ideal gas equation and the real gas equation. Why are these two values so different? (aCO=14 ...
Question 1 Decide why the heat from a candle flame is barely tolerable when a person places his or her hand above the candle compared to when the hand is placed next to the candle. The highest temperature is at the tip o ...
In the reaction of meso-stilbene dibromide, KOH and triethylene glycol and heat, if the KOH has a purity of 85% and the remainder is water; why did the mixture appear to boil?
1.) What is the purpose of making derivatives of unknowns? 2.) Give three reasons why acetone might interfere with your results. 3.) An unknown sample does not react with 2,4-dinitrophenylhydrazine reagent, but a color c ...
1. The stress induced in a column subjected to an eccentric load is given by the following equation; P/A = (S yc /[1+(ex/k 2 )sec((l/2k)(√(P/AE)))]) where P is the axial load (lb f ), A is the cross-sectional area of the ...
1. If you wish a buffer to have a pH of 10.00, what is the desired [H 3 O + ]? 2. In the buffer from 6, you want to select a weak acid (one of the conjugate pair) with a Ka close to that value of [H 3 O + ]. Explain why, ...
