Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom.

What mass of nitrous oxide gas (N2O) is contained in 40.0 L balloon at a pressure of 130.0 kPa and a temperature of 25 °C?
tamaranim1 [39]

The mass of the N₂O in the given question is 92.4g.

<h3>What is the moles of N2O in the given conditions?</h3>

STEP1- Apply the ideal gas equation

            PV=nRT

STEP2- Put the given values in the equation

            P=130kPa,     T=298K,     V=40L  R=8.31

STEP3- Solve the equation

           N=PV/RT,

           N=130×40/8.31×298

             N=2.1moles

             N=mass/molecular mass

             mass=2.1×44

            mass = 92.4g

Hence, the mass of N₂O is 92.4g.

Select the correct text in the passage.

Answer:

The answers are

1. Scientists use seismometers to measure the earthquake activity that occurs beneath a volcano. They then predict the eruption of that volcano.

2. Scientists measure the amount of these gases to determine the amount of magma present in the volcanic reservoir.  

Explanation:

When a volcano is near eruption Earthquake activity gets stronger and stronger. Scientists use a wide variety of techniques to monitor volcanoes, including seismographic detection of the earthquakes and tremor that almost always precede eruptions, precise measurements of ground deformation that often accompanies the rise of magma, changes in volcanic gas emissions, and changes in gravity and.

Scientists can use the FTIR or Fourier Transform Infrared Spectrometer to measure dissolved volatile concentrations as described above or can be used to measure several gases emitted from a volcano simultaneously. The device can be used both as an open-path or closed-path system. I had just taken the test and got the question right as well
