If you’re referring to he red stuff- the liquids can be ethanol, toluene, kerosene, or isoamyl acetate. They’re transparent so they’re made more visible with red dye. (So I’d guess the answer is ethanol)
I found this in the Wikipedia article ‘Alcohol thermometer’
Answer:
Data is a specific measurement of a variable – it is the value you record in your data sheet.
Explanation:
i dont know if that helps but i hope it does :)
A sodium chloride is like most of the ionic compounds
existing here on earth in which they are composed of having a high melting
point and by this, if found in underground rock deposits, they are usually in a
form of solid.
Make 2 in 102 as the power of 10
10^2 = 100
101 - 10^2 = 101 - 100 = 1
Hope it helped:)
Answer:
![m_{solute}=26.8g](https://tex.z-dn.net/?f=m_%7Bsolute%7D%3D26.8g)
Explanation:
Hello.
In this case, since the definition of by-mass percent is:
![\%m/m=\frac{m_{solute}}{m_{solution}}*100\%](https://tex.z-dn.net/?f=%5C%25m%2Fm%3D%5Cfrac%7Bm_%7Bsolute%7D%7D%7Bm_%7Bsolution%7D%7D%2A100%5C%25)
Whereas we know the percent as 11.9 % and the mass of the solution as 225g, so we compute the grams of solute as follows:
![m_{solute}=\frac{\%m/m*m_{solution}}{100\%}\\ \\m_{solute}=\frac{11.9\%*225g}{100\%}\\ \\m_{solute}=26.8g](https://tex.z-dn.net/?f=m_%7Bsolute%7D%3D%5Cfrac%7B%5C%25m%2Fm%2Am_%7Bsolution%7D%7D%7B100%5C%25%7D%5C%5C%20%5C%5Cm_%7Bsolute%7D%3D%5Cfrac%7B11.9%5C%25%2A225g%7D%7B100%5C%25%7D%5C%5C%20%5C%5Cm_%7Bsolute%7D%3D26.8g)
Best regards.
