Over to the right of the spill are a number of containers that have been used recently. These containers enclose chemical compounds in solid form that are commonly utilized in your lab. They are- barium sulfite, sodium chloride, potassium nitrite, iron (III) nitrate, sucrose, sodium carbonate, lithium sulfate, naphthalene, potassium permanganate, barium nitrate and copper (II) chloride, potassium sulfite, salicyclic acid.
Thinking the solid is a mixture of chemicals that are generally used in your lab, you require to test the mixture to see which method of waste disposal is correct. Propose a flowchart to test the solid to find out what it might be. The flowchart must obviously state the chemicals needed for each test as well as illustrate the expected test results.
milk of magnesia is a suspension of magnesium hydroxide in water. a common medicine it is often used as an antacid
2.00 L of H2 at a pressure of 398 torr and 1.00 L of N2 at an unknown pressure. If the total pressure in the flasks is 331 torr after the stopcock is opened,
produces carbon dioxide and water. After 5.6 of ethanol (density = 0.789 ) was allowed to burn in the presence of 12.5 of oxygen gas, 3.10 of water (density = 1.00 ) was collected. Determine the theoretical yield of H2O and the percent yield for th..
Calculate the mass of ethylene glycol (C2H6O2) that must be added to 1.00 kg of ethanol (C2H5OH) to reduce its vapor pressure by 11.9 torr at 35°C. The vapor pressure of pure ethanol at 35°C is 1.00 multiplied by 102 torr
Using the periodic table, arrange the atoms in each of the following sets in order of increasing electronegativity: a) CL, F, Br; b) B, O, N; c) Mg, F, S
The standard free energy change associated with the dissolution of ammonium nitrate in water is -6.73 kJ/mol at 298.15 K. NH4NO3(s)->NH4NO3(aq) What is the equilibrium constant for the reaction. (R=8.314 J/K*mol)
a 2.89 g sample of solid calcium carbide cac2 reacted with water to produce acetylene gas c2h2 and aqueous calcium
You are expected to design a car that works with photovoltaic panels. Assume that the driver is 75kg and the expected speed is 50km/hr.
A solution of potassium permaganate is standardized with iron metal, a primary standard. The iron is dissolved in acid, reduced to Fe(II), and titrated with permanganate.
What chemical reaction (formula) is involved in the thermal decomposition of ammonium persulfate (NH42S2O8)
The excess EDTA from this reaction required 19.77 mL of 0.01883 M Pb2+ standard solution to reach an end point. Calculate [Cu2+] in the unknown
Assume that the density of the mixed solutions is 1.00 g/mL, that the specific heat of the mixed solutions is 4.18 J/(g celcius), and that no heat is lost to the surroundings. The deltaHrxn for the neutralization of NaOH with H2SO4 is -114 kJ/mol ..
