Choosing the material with the highest specific heat capacity is ideal and true.
What is Specific heat capacity?This is defined as the quantity of heat needed to raise the temperature per unit mass.
Insulators have a higher specific heat capacity as it takes more time for them to absorb heat thereby making it ideal in building an insulated home.

A mixture of heptane (bp 98oC) and 1-propanol (bp 97oC) is not fully resolved using SE-30 as the stationary phase, but is easily separated using a column of DEGS. Explain with your own words.
A mixture of heptane and 1-propanol easily dissolved using DEGS because diethylene glycol sussinate (C8H14O6) 1 propanol easily dilutes and retain surface.
What is mixture?Generally, a mixture speaks to the joining of two different substance in other to achieve a different substance or something combining or becoming matched.
In conclusion, SE-30 is neutral in nature, DEGs is a stationary phase containing a non-volatile liquid phase. It also includes polar group OH types,
Hence, using Hydrogen bonding it can easily bind 1-propanol.

Answer:
10.25
Explanation:
There I proved it
Answer:
pOH = 12.10
Explanation:
pOH = 14 - pH = 14 - 1.90 = 12.10
A buffer solution must contain: Select one: a relatively high amount of both an acid and its conjugate base dissolved in water a relatively high amount of the conjugate base dissolved in water a solution that is at pH 7 a relatively high amount of a weak acid dissolved in water a solution that does not contain water
A buffer solution must contain relatively high amount of both an acid and its conjugate base dissolved in water.
What is a Buffer Solution?A buffer solutrion is a soltion that contains appreciable amounts of a
