the principle of quantification via standard addition. Give (in general terms, without going into specific details) an example of an analytical problem/error that can be corrected for using standard addition, and explain how the internal standard helps to correct that problem/error. Then illustrate graphically how quantification of an unknown sample is done in chromatographic analyses using standard addition (as opposed to external calibration).

Can someone explain how to determine which is more stable in
simple layman terms because I don't understand which is more stable
just by looking.
I understand how it is supposed to look in a 3d format, I
understand bond angles and strains but I must not fully understand
if I cant look at these two and know which is more stable. Thanks
in advance!

How well materials conduct heat matters when designing houses, for example. Conductivity is measured in terms of watts of heat power transmitted per square meter of surface per degree Celsius of temperature difference on the two sides of the material. In these units, glass has 1. conductivity about 1. The National Institute of Standards and Technology provides exact data on properties of materials. Here are measurements of the heat conductivity of 10 randomly selected pieces of a particular type of...

How would you define a “market” in the economics sense of the word? Give an example of a market for a good or services that does not rely on a physical store or location. (2 points) 1. How has technology affected how markets are formed (think in terms of transaction costs)? How might this affect prices? 2. How can a price ceiling that has been imposed on a particular product create a shortage? Provide a specific example. Think about whether...
