Answer:
b. source
Explanation:
The source is where something comes from. i.e. The source of sunlight is the sun.
Answer:
Electrospray ionization
Explanation:
Electrospray ionization Is a soft ionization technique used in producing ions from macromolecules, it is employed especially in spectrometry where high voltage is used to create an aerosol from a liquid.It can be employed in Knowing molecular weights of molecules and biological macromolecules such as Peptides and proteins. Therefore, electrospray ionization is the method typically requires analyte ions to be in solution prior to reaching the interface between the column in liquid chromatography and the mass spectrometer
The temperature if the volume were changed to 225 ml at a pressure of 785 torrs is 129K.
Pressure is constant.
so
V1 / T1 = v2 / T2
so
T2 = V2 T1 / V1
T2 = 225 x 242 / 422
T2 = 129K
What is temperature?
Temperature is a measure of hotness or coldness expressed on several scales, including Fahrenheit and Celsius. Temperature indicates the direction in which thermal energy spontaneously flows - ie, from a hotter body (one at a higher temperature) to a colder body (another at a lower temperature).
The Fahrenheit temperature scale (°F) is used in the United States and some other English-speaking countries. The Celsius temperature scale (°C) is standard in almost all countries that have adopted the metric system and is widely used in science. The Kelvin (K) scale, the absolute temperature scale is recognized as the international standard for scientific temperature measurement.
