Why do you think it is necessary to break up the fat into tiny droplets?

Chemistry

Nookie1986 [14]2 years ago

Answer:

for the first question, the context is necessary in order to answer...

Fat is immiscible (does not mix) with water because fat is nonpolar and water is polar (remember like dissolves like: polar mixes with polar, nonpolar with nonpolar).

soap bubbles by having many soap molecules surround fat molecules with their nonpolar end, and direct their polar ends outwards.

For your second question:

Dirt and oil are nonpolar.  When we wash our bodies with water (which is polar) it does not do a good job in removing these nonpolar molecules.  Soap, on the other hand, has a long nonpolar end and a small polar end.  The nonpolar end of the soap molecule attaches to the dirt and oil on your skin and when the water from the shower head hits the soap, it pulls the dirt, oil, and soap off of you by attaching itself to the polar end of the soap molecule.

Would the molecules in a gas have more or less movement than the molecules in a solid ? PLEASE HELP WILL MARK BRAINLY
Sergeeva-Olga [200]

Molecules in a gas will have more movement than molecules in a solid. This is because the molecules in solid matter are packed very tightly together to maintain its shape, whereas with gases they are spaced much further apart and fairly free to move. Hope this helps!

A sample of nitrogen gas had a volume of 500. mL, a pressure in its closed container of 740 torr, and a temperature of 25 °C. Wh
iren2701 [21]

Answer:  Thus the new volume of the gas is 530  ml

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas =  740 torr

P_2 = final pressure of gas = 760 torr

V_1 = initial volume of gas = 500 ml

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 25^oC=273+25=298K

T_2 = final temperature of gas = 50^oC=273+50=323K

Now put all the given values in the above equation, we get:

\frac{740\times 500}{298}=\frac{760\times V_2}{323}

V_2=530ml

Thus the new volume of the gas is 530 ml

By default, your numerical entry is scored as correct if it is within 1% of the correct answer. A rule of thumb is always to ent
IrinaK [193]
1) Multiply the correct answer by 1% => 7.80009 * 1/100 = 0.0780009

2) Calculate minimum and maximum values:

a) Maximum: 7.80009 + 0.0780009 = 7.8780909

b) Minimum: 7.80009 - 0.0780009 = 7.7220891

3) Valid range: [7.7220891, 7.8780909]

4) Conclusion: 7.80, 7.730 and 7.80703 are inside the range and are inside the tolerance, while 7.6363, 7.6 and 7.76 are not.
