The smallest units of matter that normally CANNOT be broken down are atoms. molecules. cells. phospholipids.

olya-2409 [2.1K]

Answer: atoms

Explanation:

All matter is made up of smaller indivisible particles called atoms. These atoms are the smallest units of matter ACCORDING to the Dalton's Atomic theory.

Molecules are combined atoms, while cells and phospholipids are complex combination of atoms.

Therefore, atoms is the answer

The density of gold is 19.32 g/mL. What is the volume, in mL, of a nugget of gold with a mass of 55.07 g?

Vika [28.1K]

Answer: 2.850

Explanation:

$19.32=\frac{55.07}{v}\\19.32v=55.07\\v=\frac{55.07}{19.32}=\boxed{2.850 \text{ mL}}$

Calculate the work, w, gained or lost by the system when a gas expands from 15 L to 45 L against a constant external pressure of

marta [7]

Answer:

Work done by the system = 4545 J

Explanation:

The expression for the calculation of work done is shown below as:

$w=-P\times \Delta V$

Where, P is the pressure

$\Delta V$ is the change in volume

From the question,

$\Delta V$ = 45 - 15 L = 30 L

P = 1.5 atm

$w=-1.5\times 30\ atmL$

Also, 1 atmL = 101 J

So,

$w=-1.0\times0.75\times 101\ J=-4545\ J$ (negative sign implies work is done by the system)

<u>Work done by the system = 4545 J</u>
