A long solenoid that has 1,150 turns uniformly distributed over a length of 0.380 m produces a magnetic field of magnitude 1.00 10-4 T at its center. Explain what current is required in the windings for that to occur?
How many grams of sodium formate, NaCHO2, would have to be dissolved in 1.2 L of 0.13 M formic acid (pKa 3.74) to make the solution a buffer for pH 3.61
In which of the following organ does both physical and enzymatic digestion of lipids occur
One tablespoon of peanut butter has a mass of 15g . It is combusted in a calorimeter whose heat capacity is 130kJ/ degrees C . The temperature of the calorimeter rises from 22.1 degrees C to 25.2 degrees C. Find the food caloric content of peanut ..
While performing sn2 chemistry- synthesis of 1-bromobutane from butan-1-ol, Explain what would be the purpose of refluxing the RXN mixture for 30 minutes as an alternative of just boiling and what would need modified if you used 1-chlorobutane ins..
Urea (NH2)2CO is prepared by reacting ammonia with carbon dioxide. The byproduct is water. 637.2 g of ammonia are reacted with 787.3 g of carbon dioxide. Which of the two reactants is a limiting reactant.

assume that you have two unlabled bottles, one with cyclohexane and one with cyclohexene. How could you tell them apart by carrying out chemical reactions
Having trouble with a couple of study guide questions for Chemistry. Hoping someone can assist: PART 1: Calculate the pH of a buffer solution that is 0.250 M in HCN
You inherit a gold bar that measures 7.0 inches by 3.0 inches by 2.0 inches. How many ounces does the bar weigh?
A chemistry student needs 80.0mL of acetone for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of acetone is 0.790g cm^-3.
a 486 mL sample of water was cooled from 50C to 10C. assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred.
We had a 0.10 M solution of acetic acid in water. We then placed 2 mL of the 0.10 M solution and 2 mL of toluene into a dropper and mixed. We did some magic and had
