What compound is composed of 3 fatty acids and glycerol?

PLEASE HELPP!!!!

Natasha_Volkova [10]

Answer:

The combined law is:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

See the derivation below.

Explanation:

1. Boyle's law:

$PV=constant\\\\P_1V_1=P_2V_2$

2. Charles' law:

$\dfrac{V}{T}=constant\\\\\\\dfrac{V_1}{T_1}=\dfrac{V_2}{T_2}$

3. Gay-Lussac’s law

$\dfrac{P}{T}=constant\\\\\\\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

4. Summary:

PV = K

V/T = K'

P/T = K''

Mulitply PV by V/T and P/T

$PV\times \dfrac{V}{T}\times \dfrac{P}{T}=K\times K'\times K''\\\\\\\dfrac{P^2V^2}{T^2}=constant\\\\\\\sqrt{\dfrac{P^2V^2}{T^2}}=\sqrt{constant}\\\\\\\dfrac{PV}{T}=constant$

Thus:

$\dfrac{P_1V_1}{T_1}=\dfrac{P_2V_2}{T_2}$

Which is the combined law.

An atom has eight protons and nine neutrons. draw the atomic structure of the atom

Cloud [144]

Draw eight circles and nine more in a big circle = this represents your nucleus
draw eight electrons (since electrons = protons in neutral elements) outside of it (2 in one ring, then 6 in a second ring)

How many moles of oxygen must be placed

umka21 [38]

Answer: 0.245 moles of oxygen must be placed in the container to exert the given pressure at the given temperature. The Ideal Gas Law equation gives the relationship among the pressure, volume, temperature, and moles of gas.

Further Explanation:

The Ideal Gas Equation is:

$PV = nRT$
