  • How to solve this redox question: CH3OH + MnO2 = Mn^2+ + CO2?

    Best answer: I'd go with this .. .. 1 CH3OH + 3 MnO2 + 6 H(+) ---> 3 Mn(2+) + 1 CO2 + 5 H2O ********* memorize these 7 steps to balancing redox reactions (1) identify the oxidation state of each and every atom (2) determine which atoms are oxidized and which are reduced (3) write half reactions.. include electrons... show more
    Best answer: I'd go with this
    .. .. 1 CH3OH + 3 MnO2 + 6 H(+) ---> 3 Mn(2+) + 1 CO2 + 5 H2O

    *********
    memorize these 7 steps to balancing redox reactions
    (1) identify the oxidation state of each and every atom
    (2) determine which atoms are oxidized and which are reduced
    (3) write half reactions.. include electrons
    (4) balance the electrons in the half reactions
    (5) combine half reactions and cancel electrons
    (6) rearrange the atoms into their correct chemicals and add counter ions
    (7) add any remaining chemicals.. THEN balance them

    *** 1 ***
    on the left
    .. O in CH3OH is -2
    .. H in CH3OH is +1
    .. C in CH3OH is -2... why? CH3OH has 0 net charge.. 1xC + 4*(+1) + 1*(-2) = 0
    .. Mn in MnO2 is +4
    .. O in MnO2 is -2

    on the right
    .. Mn is +2
    .. C in CO2 is +4
    .. O in CO2 is -2

    *** 2 ***
    remember this
    .. "reduction means reduction in charge".... (better is reduction in oxidation state)

    for this reaction
    .. Mn went from +4 to +2 and was REDUCED
    .. C went from -2 to +4 and was OXIDIZED

    all the H's and O's remained the same

    *** 3 ***
    half reactions
    .. Mn(+4) + 2 e's ----> Mn(+2)
    .. C(-2) ----> C(+4) + 6 e's

    *** 4 ***
    balance e's... 3x the reduction half
    .. 3 Mn(+4) + 6 e's ----> 3 Mn(+2)
    .. 1 C(-2) ----> 1 C(+4) + 6 e's

    *** 5 ***
    combine half reactions
    .. 3 Mn(+4) + 6 e's + 1 C(-2) ----> 3 Mn(+2) + 1 C(+4) + 6 e's

    cancel e's
    .. 3 Mn(+4) + 1 C(-2) ----> 3 Mn(+2) + 1 C(+4)

    *** 6 ***
    rearrange and add counter ions as necessary
    .. 1 CH3OH + 3 MnO2 ---> 3 Mn(2+) + 1 CO2

    *** 7 ***
    add remaining species
    ... we can see we have 4 H's on the left and no H's on the right.. ..so we need 4 more on the right
    ... we can see we have 7 O's on the left and 2 on the right... so we need 5 more on the right
    adding those gives
    .. 1 CH3OH + 3 MnO2 ---> 3 Mn(2+) + 1 CO2 + 4 H(+) + 5 O(-2)

    now when we start adding H(+)'s and O(-2)'s, we usually group those into water..
    .. 1 CH3OH + 3 MnO2 ---> 3 Mn(2+) + 1 CO2 + 2 H2O + 3 O(-2)

    and we still have 3 extra O(-2)'s on the right without H's to make H2O.. so we need to add some H+ on the left
    .. 1 CH3OH + 3 MnO2 + 6 H(+) ---> 3 Mn(2+) + 1 CO2 + 2 H2O + 3 H2O

    and cleaning up the equation by combining the H2O's
    .. 1 CH3OH + 3 MnO2 + 6 H(+) ---> 3 Mn(2+) + 1 CO2 + 5 H2O

    You can find lye in some hardware stores - often in the "drain cleaning" section. You need to be very careful that you're getting "100% sodium hydroxide" - do not buy it if it's not.

    The website "ThoughtCo" suggests two ways to get zinc - from pennies and from batteries (https://www.thoughtco.com/ways-to-get-zi... There involve smelting (or the separation of physical states) and require good practices to avoid burning the house down. It appears to be easier to buy zinc from a chemical supply house. They are surprisingly common in most towns. Look in the yellow pages to find one near you.

  • 'O' is an atom of oxygen, while 'O₂' is a molecule of oxygen: Is this correct?

    Best answer: Yes, that is correct; however, I think you have some underlying questions inside of that inquiry.

    O₂ is one of the diatomic homo(same)nuclear(atom) molecules, much like N₂, which are both major components of our Earth's atmospheric gas make up, and they are hardly ever found in a gaseous monoatomic form. A major difference is that O₂ is readily reactive, just look at those wildfires in CA roar from the O₂ reactants in the air, but N₂ is highly inert. O, while being technically on the periodic table as AN oxygen atom, is almost never seen in the atmosphere or anywhere else and without fail in every reaction you will ever see with oxygen being used as a reagent will show it as O₂(g). However, you can find its other form O-(aq), the really bad radical form of oxygen that IS monoatomic, think mutations... cancer and aging, pretty commonly found in solutions most especially in physiological liquids of the body! When people talk about antioxidants being good for you, this type of oxygen is the major culprit from which they are protecting you. You can also find the gaseous form of O-(g), but it requires a lightning strike or UV radiation upon O₂(g), and VERY rapidly goes on to form ozone, O3(g). Also, O-(g) is found in the lower orbit of the thermosphere, areas of which can be up to 96% saturated with it! Lastly, just for an aside, there is even solid oxygen O8(s), fun fact.

    So, while your written question only asked for a simple answer, it seemed as though you wanted to understand oxygen a lot better, and I hope that now you do :-)

    Have a great time in Chemistry! The things you learn will astonish you.

  • Where can I buy Zinc Powder and Sodium Hydroxide??? (in georgia)?

    Best answer: An independent pharmacist might be your best bet; or, can someone drive you to Dawsonville? If so, call The Lab Depot (about an hour up Route 19), which sells chemical supplies to laboratories. They might take pity on you if you explain about having a school experiment.

    Best answer: "Phlogiston" was removed from any list of "elements" in the late 1700s (around 1790) when Lavoisier demonstrated the existence of an element called Oxygen, and how "fire" was the result of the rapid combination of oxygen with other material.

    Since the first attempts at creating a periodic table happened after 1850, then we know that "fire" (phlogiston) was never included in the periodic table, having been proven non-existent more than 50 years before that.

    Since "fire" is the result of the rapid oxidization of "stuff", then look for elements that have properties close to oxygen, when it comes to valence and electronegativity: they include Oxygen itself (of course), chlorine, fluorine, and so on.
    Therefore, the answer to your question would be: In the top-right corner of the periodic table (if you exclude the noble gases in the last column).

    To oxidize material with a reaction that we describe as "fire", the oxidizer must (normally) be available in gas form, so that the burning material can evaporate molecules that violently react with the oxidizer in a way that releases heat, itself sufficient to sustain the rapid evaporation of "burning material".

    There; aren't you sorry you asked?

  • Has anyone tried smoking ammonium nitrate in a pipe. If not then why?

    They make nitrous oxide by thermal decomposition of ammonium nitrate and if that's the case then why don't people just put ammonium nitrate in a pipe and light it up.
