Answer:

The correct option is: c. phospholipid      

Explanation:

Phospholipids, also known as glycerophospholipids, are the derivatives of fatty acids which is a major structural component of the cell membranes.

Phospholipid is the class of lipids that is composed of a <u>glycerol molecule that forms ester bonds with the two long-chain fatty acids and one phosphate group.</u>

<u>Therefore, Molecule A is a </u><u>phospholipid.</u>

0.0400 M solution of HClO2, pH = 1.80 solve for Ka
umka2103 [35]
Ka for weak acids is ---> Ka= (X)²/ (initial- X)

initial= 0.0400 M

to find X, you can find the H concentration using pH

[H+]= 10^-pH
[H+]= 10^-1.80= 0.016 which is X

ka = (0.016)²/ (0.0400 - 0.016) = 0.011

You start with a container that is 8L big and the temperature in the room is 326K.
Ket [755]

Answer:

The new volume is 8.64 L.

Explanation:

Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure. For a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:

\frac{V}{T} =k

Being an initial state 1 that modifies its conditions until a final state 2, it is fulfilled:

\frac{V1}{T1} =\frac{V2}{T2}

In this case:

  • V1= 8 L
  • T1= 326 K
  • V2= ?
  • T2= 352 K

Replacing:

\frac{8L}{326 K} =\frac{V2}{352 K}

Solving:

V2=352 K*\frac{8L}{326 K}

V2= 8.64 L

<u><em>The new volume is 8.64 L.</em></u>
