How do you figure out formal charges on the Lewis dot structures? For instance I require help with finding sulfur dioxide. Explain how to do the structure just not how to do the charges.
A gas sample has an original volume of 650 ml when collected at 750 mm and 30°C. If a change is made in the gas temperature which causes the volume of the gas sample to become 800 ml at 1.00 atm, what is the new temperature
Use the values of Ka1 = 0.056 and Ka2 = 5.4 x 10-5 to calculate the [OH-] in a 0.898 M solution of oxalic acid (H2C2O4). Use E notation and 3 significant figures.
when carbon is burned in the presence of oxygen, the carbon and oxygen combine to produce carbon dioxide. if you start with 3 grams of carbon and 8 grams of oxygen and they react completely, how many grams of carbon dioxide will be produced?
What is the probability of populating the first excited vibrational state (n = 1) at 298 K? Does isotopic substitution affect the probability? Would the intensity of absorption peaks be affected by isotopic substitution?
The first-order reaction SO2Cl2 --> SO2 + Cl2, has a rate constant of 2.20 x 10^-5 s^-1 at 593 K. What percentage of the initial amount of SO2Cl2 will remain after 2.00 hours
disubstituted alkene was formed in which the olefinic protons exhibited a vicinal coupling of 9.0Hz in the H NMR. What is the stereochemistry
The reactant concentration in a first-order reaction was 6.70×10-2 after 25.0 and 3.30×10-3 after 100 . What is the rate constant for this reaction?
What mass of sucrose should be combined with 461 g of water to make a solution with an osmotic pressure of 8.85 atm at 310 K? (Assume the density of the solution to be equal to the density of the solvent.)
30.0 mL of 0.500 M KOH are needed to neutralize 10.0 mL of HCl of unknown concentration.HCl + KOH ? KCl +H2O Show your work.
Identify whether or not solutions of these salts will form an acidic or basic or neutral solutions when added to water.
a gas sample containing 1.55 mol at 25degc exerts a pressure of 387 torr. some gas is added to the same container and
In a titration, a 0.7529 gram sample of a mixture of solid C6H5COOH and solid NaCl is dissolved in water and titrated with 0.150 M NaOH. The equivalence point is reached when 24.78 mL of the base solution is added.
