Imagine you're cooking dinner for a few of your friends. You decide to make a salad with homemade dressing. Why do you need to think about the polarity of the different ingredients in your salad dressing in order for it to turn out well? Answer in 1 to 2 paragraphs. (10 points) Think about how polar molecules only mix with other polar molecules and nonpolar molecules only mix with other nonpolar molecules. ANSWER PLEASE

1.The compound in medicines should be nonpolar because of many reasons.  First off, it is important for any drug to be able to dissolve itself through the cell membrane which consists of a lipid bi-layer, in order perform its function. Non polar compounds are lipid soluble and can dissolve in the lipid layers. Polar compounds are water soluble and cannot cross the cell membrane. Because of this, scientists need to be sure of using compounds that are nonpolar in nature so they are able to pass through the cell membrane and enter into the blood circulation of the body and perform its function.

2.You need to think about the polarity of the dressing in order for it to turn out well because the different ingredients inside the dressing have to be able to dissolve or mix together well or else the consistency will be clumpy or separated. With polarity only, like-polarities dissolve like-polarities. So you must make sure that all your ingredients are polar or all are nonpolar. If you have some ingredients that are polar and some that are nonpolar, the dressing won’t turn out smooth like you want it to.

an honest friend. a friend who cares about me, and wont use me. a friend that i can trust. not someone who is fake

mark this brainliest lol i need one more.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
