    What are the similarities and differences betwixt a unicycle and a wheel?

    Just from the words themselves, the astute Latin-speaking scholar can tell that, whatever it is made of, the unicycle has one of them (uni = "one") and the bicycle has 2 (bi = "two"). From pictures, we get additional data that helps us tell the ii apart. The unicycle has one wheel and the bicycle has two. In particular, they are fabricated up of the same materials, and the merely significant difference is the number of wheels on the two vehicles. Now—how many wheels are on a tricycle?

    Law of Multiple Proportions

    Once the idea that elements combined in definite proportions to form compounds was established, experiments besides began to demonstrate that the same pairs of certain elements could combine to form more than one chemical compound. Consider the elements carbon and oxygen. Combined in one way, they form the familiar compound carbon dioxide. In every sample of carbon dioxide, there are \(32.0 \: \text{g}\) of oxygen present for every \(12.0 \: \text{g}\) of carbon. By dividing \(32.0\) by \(12.0\), this simplifies to a mass ratio of oxygen to carbon of ii.66 to i. There is some other compound that forms from the combination of carbon and oxygen chosen carbon monoxide. Every sample of carbon monoxide contains \(16.0 \: \text{g}\) of oxygen for every \(12.0 \: \text{g}\) of carbon. This is a mass ratio of oxygen to carbon of 1.33 to one. In the carbon dioxide, there is exactly twice as much oxygen present as there is in the carbon monoxide. This example illustrates the law of multiple proportions: whenever the aforementioned ii elements form more than one chemical compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers.

    In carbon monoxide, on the left, at that place is \(1.333 \: \text{m}\) of oxygen for every \(ane \: \text{g}\) of carbon. In carbon dioxide, on the right, there is \(2.666 \: \text{g}\) of oxygen for every gram of carbon. And so the ratio of oxygen in the two compounds is 1:2, a small whole number ratio.

    The difference between carbon monoxide and carbon dioxide is pregnant. Carbon monoxide is a deadly gas, formed from the incomplete combustion of some carbon-containing materials (such as wood and gasoline). This chemical compound will attach to hemoglobin in the red claret cells and cake the binding of oxygen to those cells. If oxygen does not bind, information technology cannot be carried to the cells of the body where it is needed, and death can occur. Carbon dioxide, on the other mitt, is not toxic like carbon monoxide is. However, it can displace oxygen in systems since it is heavier. Carbon dioxide fire extinguishers cutting off the flow of oxygen in a fire, putting out the fire.

    Summary

    • The law of multiple proportions states that whenever the same ii elements form more than one chemical compound, the different masses of one chemical element that combine with the same mass of the other chemical element are in the ratio of small whole numbers.

    Review

    1. State the law of multiple proportions.
    2. In carbon dioxide (CO2), how many grams of oxygen (O) would there be if there are 24 grams of carbon (C)?
    3. How many grams of carbon (C) would exist present in carbon monoxide (CO) that contains two.666 grams of oxygen (O)?
