A 40-year old weighs 150 lb experience abdominal pain and says he consumed two 12oz bottle of beer. The alcohol in the beer is about 5 % alcohol and he said he was drinking over a hour. State the chemical reaction that took place in the body.
What is the pH of a solution made by dissolving 46g of acetic acid in enough water to make 700 ml of solution
Calculate the molar mass of the biomolecule. For carbon tetrachloride, the boiling point constant is 5.03°C · kg/mol, and the boiling point of pure carbon tetrachloride is 76.50°C.
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.
If the absolute temperature of a gas is doubled, what happens to the root-mean-square speed of the molecules?
Commercial concentrated aqueous ammonia is 28% by mass and has a density of 0.90 .What is the molarity of this solution?
When 2.20 grams of Cr(CO)6 reacts according to the following equation at 400 °K in a closed system the temperature goes down and 5.2 kJ of hear is absorbed
If 2.45 g of N2H4 reacts and produces 0.650 L of N2, at 295 K and 1.00 atm, what is the percent yield of the reaction?
What is the simplest formula for Chalcocite if a sample of this ore contains 8.274 g copper and 2.088 g sulfur?
H2S (aq) is a polyprotic acid, meaning it can dissociate its hydrogen ion more than once. However, HS- (given its negative charge as well as its extra hydrogen ion) can act as either a base or an acid
Is the reaction exothermic or endothermic? b) Calculate the heat produced when 10.0 g of AlCl3 forms. c) How many grams of Al are required to produce 1.00 kJ of energy?
