  • I still don't have my tax return?

    I've filed everything, and then got a letter saying that the IRS needed to further verify my identity, so went into the office, and got that taken care of on April 5th. Said that after 21 days, they'd have my refund out to me.

    Well. It's August. And when I go to the "Where's my Refund" page, I get a "your tax return is still being processed". Anyone possibly know what's the deal? Going to head down to the office in a few days, because this is ridiculous.

  • Avogadro's Law and Gas Stoichiometry?

    Suppose that 2L of propane gas (C3H8) at 1 atm and 298K is mixed with 7.4L of O2 gas at the same pressure and temperature and burned to form CO2 gas and H2O. Ignoring the volume of water forward, find the final volume of the reaction mixture (including products and excess reactant) at 1 atm and 298K if the reaction goes to completion.

    Answer in units of L.

    So....I balanced it:

    C3H8 + 5O2 ---> 3CO2 + 4H2O

    I'm more confused with the "include products and excess reactant" part....

  • For the reaction 2C6H6 + 15O2 → 12CO2 + 6H20.....?

    2C6H6 + 15O2 → 12CO2 + 6H2O

    39.6 g of C6H6 are allowed to react with 133.8 grams of O2. How much CO2 will be produced by this reaction?

    Help? I've got it balanced, but other than that, I'm lost.

  • STP Chemistry Problems?

    I dont' know how to convert the answers to problems into STP, it just doesn't make sense. even a good website that explains this is good too. just. help?

    ex:

    Hydrogen is collected over water at 19C and 785 mmHg of pressure. THe total volume of the sample was 1.93L Calculate teh volume of hydrogen at STP. Water pressure at 19C is 16.4mmHg

    And another on how to convert FROM STP.

    ex: Original volume at STP temperature adn pressure was recorded as 488.8 mL. What pressure will the gas under when put into a volume of 5.01x10(-4 power)L and a temperature of minus 245.0C?

  • What's the name of this thing that can make a drink carbonated?

    I've heard that it's a pill or tablet thingy that once you put into your drink, it becomes bubbly like a soda~ mind you, I'm not talking about alka-seltzer. My family is tired of buying bottles of club soda in order to mix drinks, so with hearing of this mysterious magical tablet/pill thingy, we were really happy, but what is that stuff called?
