Answer:

C. the view that the atom cannot be broken down further than protons

Explanation:

Atom is considered as the smallest unit of matter. An atom contains protons and neutrons in the nucleus and electrons orbiting the nucleus in fixed energy shells.

It was thought that atom cannot be broken down further than these particles until quarks were discovered. A proton contains three quarks- 2 up quarks and 1 down quark.

Type the correct answer in the box. express your answer to three significant figures. an air mattress is filled with 0.55 moles

dmitriy555 [2]

385 L is the volume of the air mattress with 0.55 moles of air inside the mattress and a temperature of 295 K.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Using the gas law,

PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.

Given data:

P= 3.5 kPa

V=?

n= 0.55 moles of air

T= 295K

R= 8.314 (L kPa/mol K)

Putting value in the given equation:

V= $\frac{nRT}{P}$

V = $\frac{(0.55 moles)(8.314 L kPa/mol k)(295 K)}{3.5 kPa}$

V = 385.4132857 L

And whatever the significant figure is asked for, for example, 3 significant figures: the answer would be 385 litres.

Hence, 385.4132857 L is the volume of the air mattress.

Kay [80]

For the compound formed to be neutral, the charge should be zero. This means that the positive charge should be equal to the negative charge. The balanced chemical reaction forming the neutral chromium oxide is shown below.
2Cr3+ + 3O2- ---> Cr2O3
