State a general rule on the structure or the length of the hydrocarbon chain of an alcohol and its solubility in water.
In order to distinguish the R and S forms of a molecule an enzyme must have binding sites for how many of the groups on the stereocenter of the molecule
If 25.0 grams of potassium chlorate decomposes, how many grams of gas are released as a product?
If 329 g water at 65.7°C loses 9730 J of heat, what is the final temperature of the water?
ferrocene fec5h52s can be prepared by reacting 3.0 g of fecl2s with an equal mass of cyclopentadiene c5h6l and an
A person ate 0.919 pound of cheese (an energy intake of 7350 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to v..
A 1.25g sample of copper ore was dissolved in acid and diluted to 250.0 mL. A 20.00 mL portion was diluted to 50.00 mL. The copper concentration of this solution was 4.62 ppm. What is the weight percentage of copper in the ore
In electrophilic aromatic substitution, why does an amide group direct substitution to a position opposite to it on the aromatic ring. The N donates electron density to the ring by induction and destabilizes the intermediate that forms meta to it
0.688g of antacid was treated with 50.00 mL of 0.5M HCl. the excess acid required 4.21 mL of 1.200M NaOH for back-titration. what is the neutralizing power of this antacid expressed as millimoles of HCl per gram of antacid
A titration required 25.0 mL of a 0.500 M NaOH to react completely with all the acid present. Assuming the unknown acid has one acidic proton per molecule, what is the molecular formula of the unknown acid
If you have 50 ml of a buffered solution of 0.15M HNO2 and 0.05M NaNO2, how many ml of 0.2M HCl can you add before the pH changes significantly
the order of the reaction was n=0 and the value of the rate constant was 3.41*10^-3 M s^-1. I could find the order of reaction and the value of the rate constant but I am clueless about how to find the rate of reaction when [A]=0.15M.
