10.00ml of the final acid solution is reacted with excess barium chloride to produce a precipitate of barium sulfate (FW = 233.4 g/mol). (Final acid solution from previous question was 0.06Molarity). The dry solid weighs 0.397g. Use this mass and the dilution volumes to calculate the ACTUAL molarity of the sulfuric acid in the INITIAL solution.
The average concentration of strontium ion in seawater is 8.00 mg of strontium ion per kg of seawater. What is the molarity of the strontium ion if the density of the seawater is 1.025 g/mL.
How much heat is produced by the complete combustion of 253g of CH4? Ch4(g) +2 O2(g) ----> CO2(g) + 2H2O (g)
Sketch a molecule of Pbr3Cl2 in which the chlorines are in axial position position. Sketch another molecules of Pbr3Cl2 in which the chlorines are equatorials positions.
the temperature of a 4.00L sample of gas is changed from 10.0c to 20.0c. what will the volume of this gas be at the new temperature if the pressure is held constant?
Al(OH)3 + 3HCl ---> AlCl3 + 3H2O Determine the moles of acid neutralized if a tablet contains 0.200 mol Al(OH)3
Calculate the mole percent composition of the mixture. Assume that the response of the detector (area per mole) is the same for each component.
Instant cold packs used to treat athletic injuries contain solid NH4NO3 and a pouch of water. When the pack is squeezed, the pouch breaks and the solid dissolves
There is an inherent flaw in the drying procedure for the gravimetric determination that causes the measured mass of BaSO4 to be erroneously high
If a sample of barium contains 2.3 x 1023 atoms of barium, how many grams of barium are in the sample?
Alfred bought a new graduated cylinder for his chemistry class. It holds 416 milliliters of liquid. If the cylinder has a radius of 4 cm, then how tall is the cylinder?
A 0.456 gram sample of an unknown monoprotic acid (let's call it HZ) was dissolved in some water (you pick the amount). Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
