How can you tell whether a fat contains primarily saturated or unsaturated fatty acids?

1 answer:

3 0

In terms of physically observing it, if the substance is a lions based substance, like oil or margarine, depending on the state, this will inform how well the hydrocarbons can pack together well or not, or will there be bends in the ring preventing the molecules from packing well.

Liquids are unsaturated
Solids are saturated.

A 12-liter tank contains helium gas pressurized to 160 \rm atm.How many 3-liter balloons could the 12-L helium tank fill? Keep i

Vikentia [17]

Answer:

636 balloons

Explanation:

If we assume that helium gas follows an ideal gas behaviour, we can use the ideal gas law to solve this problem as follows:

We consider two different states, the initial given by the conditions of the problem statement and the final, when the tank reaches atmospheric pressure and it's no longer able to fill balloons: $P_{1}=160 atm\\V_{1}=12 L\\P_{2}=1 atm\\V_{2}= ?$
To find out what would be this volume 2, we use the Boyle's Law: $P_{1}V_{1}=P_{2}V_{2}\\V_{2}=\frac{P_{1}V_{1}}{P_{2}} \\V_{2}=\frac{160 atm \times 12L}{1 atm}\\V_{2}=1920 L$
Now we find the available volume to fill the balloons by substracting both, volume 2 and volume 1: $V_{b}=V_{2}-V_{1}=1920L-12L=1908 L$
Finally, we determine the quantity of ballons by dividing that available volume between the volume of each ballon: $B=\frac{1908L}{3L} =636 balloons$

If one serving of a packaged frozen dinner contains 5.2 grams of saturated fat and the maximum recommended daily intake of satur

den301095 [7]

Answer:

The percentage of the daily value for saturated fat provided by one package of this food is 26.0%

Explanation:

It has been given from the preceding statement that one package of the dinner provides 5.2g out of the 20 grams recommended for daily need. This is 5.2/20 x 100 given 26.0% of the daily neded value will be provided by a plate or package of the dinner.

5. Why are lonic compounds good conductors of electricity?

ziro4ka [17]

Answer:

The options are unclear, however, the correct option is:

Aqueous solutions of ionic compounds cause to dissociate, hence, ions are free to conduct electricity

Explanation:

Ionic compounds are compounds formed from ions (charged atoms). For example, NaCl is an ionic compound from the following ions; Na+ (cation) and Cl- (anion). One characteristics of ionic compounds is their ability to dissociate into the ions that form them when in an aqueous solution i.e. NaCl will dissociate into Na+ and Cl- when in an aqueous solution.

These disssociated ions are free to conduct electricity, hence, making ionic compounds good conductors of electricity.
