  • What is the resulting reaction of potassium bicarbonate and citric acid?

    I finished my intro to chemistry but this is a slightly more advanced reaction than I am familiar with.

    This is not required for a test, homework, etc. I saw a company had "activator" packets that used these two in a special bottle to carbonate. So I am wondering how that is possible, since carbonic acid (formed when CO2 is forced into water) naturally decomposes if there isn't enough CO2 to keep it from separating.

    So I am wondering what the reaction is for

    C6H8O7 + KHCO3

    The formula may be wrong but it is definitely CITRIC ACID and POTASSIUM BICARBONATE. Hoping someone could explain how they make this work, or if there is another ingredient that makes this all fit together.

    Thanks all :)

  • If the engine is almost starting up, what to do.?

    I have a 98 Mercury Sable which is not staring up at the moment, here is the information on have on that.

    1) The car worked fine just a few minutes before.

    2) I was told it sounded like water in the fuel line, I put in water remover (Heet brand).

    3) Found out I should use two things of Heet, so I put in a second one.

    4) It will start for less than a second, exhaust comes out, you can hear the roar of life then it stops.

    Any help is appreciated, I heard something about starter fluid but not sure if that is the problem as it was just a guess.

  • Looking for a type of shirt?

    I have a friend who wants a very attractive piece of clothing sewn together but I cannot think of what it is called.

    Here are the important details I can remember about it:

    - It is a piece of womens clothing

    - I believe it has an open back or upper back area

    - The front is held up by collar around the neck, or else a strap that wraps around the back of the neck

    I will look up any answer, and any links/pictures would be grand.

  • Error C2533 Constructors cannot have a return type?

    // Dot.h:

    #include <iostream>

    #include <cstdlib>

    using namespace std;

    class Dot

    {

    public:

    Dot(void);

    int getValue();

    void setValue(int);

    void flick();

    int value;

    }

    // Dot.cpp:

    #include <iostream>

    #include <cstdlib>

    using namespace std;

    #include "Dot.h"

    Dot::Dot()

    {

    int value = 1;

    };

    void Dot::flick()

    {

    if (value == 1)

    value = 0;

    else

    value = 1;

    }

    int Dot::getValue()

    {

    return value;

    }

    void Dot::setValue(int val)

    {

    value = val;

    }

    For some reason I am getting the following:

    error C2533: 'Dot::{ctor}' : constructors not allowed a return type

    Now, I looked it up online for both the error code and the actual error message and the solution is usually to add a ';' at the end of the Dot constructor, I did this, and the error remains.

    Any help would be grand, thank you.

  • What does it mean to claim a child on taxes?

    Does claiming mean it is yours? Just that you have permission to claim her? That you take responsibility?

    Basically my roommate cant collect taxes as the department of education confiscates it. What does it mean if I agree to claim her daughter (and thereby any discounts or refunds from it)?

  • Does an itch about an area that is numb because of blood loss show that its coming to life or dying?

    Assume its an artery cut leng from wrist to elbow. I presume going dark colours (purple, blue, black especially) would be bad. How long should it take for blood flow to return, for feeling to come back. And as stated if the ara above a number area starts to itch, then starts to ache does that mean the nerves dying or getting back all feeling? (itch first, then pain)
