Answer:

Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.

Explanation:

The molecular mass gives the mass of a molecule relative to that of the 12 C atom, which is taken to have a mass of 12. Hence why Molecular mass is a number equal to the sum of the atomic masses of the atoms in a molecule.

Answer:

The concentration of SO₂ will decreases

Explanation:

As you can see in the reaction

2 moles of gas ⇆ 3 moles of gas

Based on Le Châtelier's principle, a change doing in a system will produce that the system reacts in order to counteract the change made.

If the pressure is increased, the system will shift to the left in order to produce less moles of gas and decrease, thus, the pressure.

As the system shift to the left, the concentration of SO₂ will decreases

Earth's magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth's interior out into space, where it interacts with the solar wind, a stream of charged particles emanating from the Sun.

Answer:

The atomic mass number does not change because a beta particle has a much smaller mass than an atom. The atomic number goes up because a neutron has turned into an extra proton, however in beta decay a fast-moving electron is fired out of the nucleolus

Answer:

Gaseous nitrogen has unique chemical and physical properties that make it suitable for use in food processing. Nitrogen is inert which means it will not react with prepared food materials, which can alter their aromas or flavors. Also, gaseous nitrogen will effectively displace oxygen minimizing oxidation and the growth of microorganisms that cause foods to lose their freshness and deteriorate faster.

Explanation:

Source: https://www.generon.com/using-nitrogen-gas-in-food-packaging/

"Because it deflects oxygen, nitrogen is just a common gas for food packing." Because oxygen will carry moisture, this is critical. Bacteria use oxygen to grow and survive on organic matter. Bacteria find it much harder to develop while as much oxygen as possible is removed.

Food packaging is the process of packaging food. A package provides security, resistance to manipulation, and particular physical, chemical, and even biological requirements.  Food packaging may include a nutrition label and other information about the product being sold.

Bacteria are commonly found, mostly free-living organisms with  one biological cell. They belong to the prokaryotic organisms category. Bacteria, which have been typically a few micrometers long, were one of the first living species to originate on Earth and may be found in practically every ecosystem.

Answer:

The more water vapor in the air parcel, the more condensation can occur, and therefore, more rain. ... The air parcel then loses more energy, causing more rainfall. Wind pushes air parcels even higher in the troposphere, where it is colder. The air parcels will then lose more energy and more rain can happen.

Cellular respiration is a metabolic pathway that allows cells to take apart food molecules and use their atoms as an energy source. This pathway takes electrons from food molecules and transfers them to oxygen, has energy transferred to ATP and arranges molecules into water, carbon dioxide and waste.

Answer: Do you have an image so I can solve it?

Answer:

81.5g/mol

Explanation:

Molar mass is the ratio between mass of a substance (In this case, 0.207g) and moles presents in this mass.

To solve this question we must find the moles of the gas in order to obtain the molar mass using:

PV = nRT

PV / RT = n

Where P is pressure = 0.980atm

V is volume in Liters = 0.0725L

R is gas constant = 0.082atmL/molK

T is absolute temperature = 68°C + 273.15 = 341.15K

0.980atm*0.0725L / 0.082atmL/molK*341.15K = n

2.54x10⁻³ moles = n

Thus, the molar mass of the gas is:

0.207g / 2.54x10⁻³ moles

The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells. The possible existence of unseen microbial life was suspected from ancient times, such as in Jain scriptures from sixth century BC India.

“Microorganisms are minute organisms that are invisible to the normal eye.” Microorganisms are so small that they can only be seen under a microscope. These include a huge range of organisms such as bacteria, viruses, fungi, algae, protozoa, etc.

Given options are-

A. adding manure or compost to the soil

B. spraying chemical weed-killers and fertilizers on the soil

C. removing all ground-covering plants from the soil

D. adding sewage containing synthetic materials to the soil

Therefore, The solution that could best help to restore or increase microorganisms and soil biodiversity is adding manure or compost to the soil.

Answer:

(a)  The unit cell edge length 0.421 nm

Explanation:

Lets calculate -:

Given -

density = [tex]3.58g/cm^3[/tex]

Molecular weight of MgO = 24.31 +16

                                           [tex]40.13 g/mole[/tex]

Avagadro number = [tex]6.022\times10^2^3[/tex]

In rock salt structure , there are four anions and four cations , hence Z=4 (Number of formula per unit cell)

Now, using the formula -

                     [tex]d=\frac{ZM}{N_Aa^3}[/tex]

               [tex]a=[\frac{ZM}{N_Ad}]]^\frac{1}{3}[/tex]

Now, putting the given values

   [tex]a=\frac{4\times40.13g/mole}{6.022\times10^2^3\times(3.58g/cm^3)}[/tex]

  [tex]4.21\times10^-^8 cm[/tex]

  = 0.421 nm

Hence , the unit cell edge length = 0.421 nm

The unit cell edge length of magnesium oxide (MgO) is equal to 0.421 nanometer.

Given the following data:

Scientific data:

To determine the unit cell edge length:

Mathematically, the unit cell edge length for a face-centered cubic (FCC) structure is given by the formula:

[tex]a=\sqrt[3]{\frac{ZM}{\rho N_A} }[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]a=\sqrt[3]{\frac{4 \; \times \;40.31}{3.58\; \times \;6.02 \times 10^{23}} }\\\\a=\sqrt[3]{\frac{161.24}{2.16 \times 10^{24}}}\\\\a=\sqrt[3]{7.47 \times 10^{-23}} \\\\a=4.21 \times 10^{-8}\;meter[/tex]

Note: [tex]1 \;nanometer = 1 \times 10^{-9} \;meter[/tex]

a = 0.421 nanometer.
