Hello!
In this case, since the parts per thousand of a solute in a solute is defined in terms of its grams per kilogram of solution (unlike parts per million which are mg/kg) we can mathematically represent it via:
Now, since the whole human body acts as the solution and the chlorine in the form of ions as the solute, the required ppth turns out:
Best regards!
The boiling point (or condensation point) of a substance is defined as the temperature at which the vapor pressure of the liquid is exactly equal to the external pressure. Above the boiling point, the substance exists as a gas and below, it exists predominately as a liquid.
<h2>Answer and Explanation </h2>
Nitrogen is present in group 5. It contains 7 electrons and protons. It has 2 electrons in its first shell and 5 electrons in second shell. In order to determine the atomic number of nitrogen, we should know about the number of protons or electrons of the atom.
Atomic number is denoted by Z. Z= number of protons. Hence, nitrogen consists of seven protons as well as seven electrons. Therefore, its atomic number (Z) will also be 7.
Wavelength of any wave can't be equal to the number with exponential of 23, otherwise, if you're focusing on visible light, and neglecting the exponential then your color would be: orange. [ Again, remember wavelengths can be in between 10 to 10^-14 ]
In short, Your Answer would be: Orange
Hope this helps!
Answer:
Oiling is done on a regular basis to sewing Machine because in the machine there are lots of machinery parts i.e. wheels and axels, etc. which are in continuous use and they possess so much frictional force between them that wear tear may be observed in those parts.
