Pressurized gas is the term that is used to describe a gas that is compressed into a smaller space than it would normally occupy at Earth's surface.

Explanation:

The purpose of compressing a gas is to lessen its volume so that it can fit in a small space. Natural gas can be compressed using a compressor and the pressure of a compressed gas is 200 to 250 bars.

Pressurized gases are used in ground processing and space flight operations.  Pressurized gas, also known as compressed gas is also used in fuel production and in gas pipelines.

When stored in a reservoir, care must be taken to avoid leakage as these gases compressed under high pressure are highly flammable.

Before measuring the absorbance of a solution with the Ocean Optics spectrophotometer, it is important to run a blank sample of
nika2105 [10]

Answer:

b. The solvent being used in the experiment.

Explanation:

The spectrophotometer indicates the absorption of the light for the substance. So, during the experiment, is necessary to put the solvent first, so the equipment will discount the absorption of it, and then, with the samples, will indicate the absorption of the solute.

5x10-6 mol Na2C2O4 bileşiğinde kaç tane O atomu vardır?
adelina 88 [10]

There are 1.204 x 10¹⁹ atoms O

<h3>Further explanation  </h3>

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

1 mol of molecule Na₂C₂O₄ :

There are 4 mol of O in 1 mol of molecule Na₂C₂O₄

So for 5 x 10⁻⁶ mol Na₂C₂O₄ :

\tt mol~O=4\times 5.10^{-6}=2.10^{-5}

1 mole = 6.02.10²³ particles , so number of atoms O :

\tt 2\times 10^{-5}\times 6.02\times 10^{23}=1.204\times 10^{19}

If 7.79 mol of NO2 occupy 17.8 L, how many liters will 4.31 mol of NO2 occupy at the same temperature and pressure?
shutvik [7]

Answer:

9.85 L

Explanation:

Use ratios to solve.

7.79/17.8 = 4.31/x

7.79x = 76.718

x = 9.85

You will have 9.85 L.
