if all sides are unequal it is scalene and if one angle adds up to 90 while the rest are different youve proven it.
Answer:
60.57g of TRIS did you use
Explanation:
The concentration of the Tris solution buffer is 0.5 molar (That is, 0.5 moles per liter). As you need to make 1L, you need to have in the solution <em>0.5 moles of TRIS.</em>
<em />
To convert these moles of TRIS to grams you need to use the molecular weight of TRIS base (121.14g/mol), thus:
0.5 moles TRIS * (121.14g / mol) =
<h3>60.57g of TRIS did you use</h3>

Answer:Sodium chloride solid is not a mixture. ... It cannot be physically separated into its components, Na+ and Cl−
Explanation:Sodium chloride is formed when sodium atoms interact with chlorine atoms. When this occurs, sodium will donate an electron (which is a negatively-charged particle) to chlorine. This makes sodium slightly positive and chlorine slightly negative.
Opposite charges attract, right? So then, sodium ions will attract chloride ions and form an ionic bond. By the way, chloride is the term used to designate the anion form of chlorine. The result is a crystallized salt that has properties that are different from the two parent elements (sodium and chlorine). The chemical formula for sodium chloride is NaCl, which means that for every sodium atom present, there is exactly one chloride atom.
