Atmospheric pressure is measured with a barometer. A barometer consists of an evacuated vertical tube with its top end closed and its bottom end resting in a container of mercury that is open to the atmosphere The pressure exerted by the atmosphere acts on the exposed surface of the liquid to force mercury up into the tube. Sea level atmospheric pressure will support a mercury column generally not more than 29.92-in. high. Thus, the standard for atmospheric pressure at sea level is 29.92 in.-Hg, which translates to an absolute pressure of 14.69 psia.
The two basic reference points in all these measurements are standard atmospheric pressure and a perfect vacuum.
The correct option is B.
Single replacement reaction is a type of chemical reaction, in which one element is substituted for another element in a compound. There are usually two reactants, one is a pure element and the other one is an aqueous compound. The products formed is usually made up of another pure element and a new compound. In the option B, you will notice that, in the reactant part, Mg is a pure element while in the product side, H2 is a pure element.
<em>In the late 1800's, experiments using cathode ray tubes led to the discovery of the;</em>
Electron(s)
<u>It was founded that many different metals release cathode rays, and that cathode rays were made of electrons, very small negatively charged particles.</u>
Answer:
A molecule of sucrose (C12H22O11) has 12 carbon atoms, 22 hydrogen atoms and 11 oxygen atoms. The subscripts also indicate the ratios of the elements.
Explanation:
This is because it has the abbreviation of the Carbon atoms, Hydrogen atoms, and Oxygen atoms are right before the number.
