What amount of Potassium Chloride forms when 5.25 litres of Chloride gas at 0.95 atm and 293 K reacts with17.0 g of Potassium?
Suppose that the solvent ethanol could serve to replace the methanol in this process, but at the expense of double the concentrations of the solvent in the atmosphere.
Chemists often use molarity ,M in Moles/liter , to measure the concentration of solutions. Molarity is a common unit of concentration because the volume of a liquid is very easy to measure
You dissolve 1.00 gram of an unknown diprotic (two titratable protons) acid in 200.0 mL of H2O. This solution is just neutralized by 5.00 mL of a 1.00 M NaOH solution. What is the molar mass of the unknown acid?
If the two flasks are connected through a stopcock and the stopcock is opened, what is the partial pressure of helium?
When NH3 is prepared from 28 g N2 and excess H2 the theoretical yield of NH3 is 34 g. When this reaction is carried out in a given experiment, only 30. g is produced.
Keep in mind that it will be too thick and greasy to insert in a capillary tube. Also, remember that the melting point of vegetable oil is well below room temperature.
A certain weak base has a Kb of 8.70 × 10-7. What concentration of this base will produce a pH of 10.10
When two atoms of 2H (deuterium) are fused to form one atom of 4He (helium), the total energy evolved is 3.83 × 10-12 joules. What is the total change in mass
If you are given a 0.31 g piece of sodium metal to react with water, how many moles of HCl would it take to neutralize the sodium hydroxide produced
A car travels at 58.0 miles per hour and gets 12.0 kilometers per liter of gasoline. How many gallons of gasoline are needed for a 1.50 hour trip?
calculate the concentration in molarity of a NaOH solution if 25.0 ml of the solution are needed to neutralize 17.4 ml of a .312 M HCl solution.
Rank the following compounds in order of lowest to highest melting point. KCl CH3-O-CH3 CH3-CH2-CH3 CH3-CH2-NH2
