Explanation:
If yeast is given more sugar will they undergo more
cellular respiration than yeast that is given less sugar?
Answer:
True
Explanation:
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.
TRUE OR FALSE?
It is not possible for wind can push an air parcel even higher in the troposphere, causing the parcel to cool and lose more energy, which will lead to more rainfall.
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.

If 27.3g of C8H18 is combusted, according to the equation below, what mass of water is produced?
2C8H18 + 25O2 --> 16CO2 + 18 H2O,
molar masses: C8H18 = 114.3 g/mol O2 = 32.0 g/mol CO2 = 44.0 g/mol H2O = 18.0 g/mol
Answer:
38.7 g
Explanation:
2C₈H₁₈ + 25O₂ → 16CO₂ + 18 H₂OFirst we convert 27.3 grams of C₈H₁₈ into moles, using the given molar mass:
27.3 g C₈H₁₈ ÷ 114.3 g/mol = 0.239 mol C₈H₁₈Then we convert 0.239 moles of C₈H₁₈ into moles of H₂O, using the stoichiometric coefficients of the reaction:
0.239 mol C₈H₁₈ * [tex]\frac{18molH_2O}{2molC_8H_{18}}[/tex] = 2.151 mol H₂OFinally we convert 2.151 moles of H₂O into grams, using water's molar mass:
2.151 mol H₂O * 18.0 g/mol = 38.7 gHowever, in day-to-day experience, the strangeness of Einstein's ideas doesn't help us, and Newton's notions do just fine.

Magnesium oxide (mgo) has the rock salt crystal structure and a density of 3.58 g/cm3. the atomic weights of magnesium and oxygen are 24.31 g/mol and 16.00 g/mol, respectively. (a) determine the unit cell edge length.
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:
Density = 3.58 [tex]g/cm^3[/tex]Atomic weight of magnesium = 24.31 g/mol.Atomic weight of oxygen = 16.00 g/mol.Scientific data:
Avogadro's number = [tex]6.02 \times 10^{23}[/tex]Z for FCC = 4Molar mass of magnesium oxide (MgO) = [tex]24.31 + 16 = 40.31 \;g/mol.[/tex]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:
Z is the number of atoms per unit cell.[tex]\rho[/tex] is the density.M is the molar mass.[tex]N_A[/tex] is the Avogadro constant.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.

3. A chemical reaction has occurred.
4. A chemical change has occurred.
Answer:
3. A chemical reaction has occured
A student mixes two liquids together and notices that a white solid has formed at the bottom of the container which means precipitate has formed.
What is precipitation reaction ?
Precipitation is the process of creating an insoluble compound in chemistry by either reacting two salts or altering the temperature to alter the solubility of the compound. Additionally, the solid that results from a precipitation reaction is referred to as "precipitate."Precipitation can be a sign that a chemical reaction has taken place, but it can also happen if the concentration of a solute is higher than its solubility. The process of small, insoluble particles aggregating together or forming an interface with a surface, such as the container wall or a seed crystal, is known as nucleation, and it occurs before precipitation.Precipitation is the process of transforming a liquid into a solid. A precipitant is a chemical that gives rise to a solid in a liquid solution. The term "precipitate" refers to the resulting solid. In the event that the molecule size of the insoluble compound is tiny or there is deficient gravity to attract the strong to the lower part of the compartment, the hasten might be equitably dispersed all through the fluid, shaping a suspension. Any process that separates the precipitate from the solution's liquid portion, known as the supernatant, is referred to as sedimentation. Centrifugation is a common technique for sedimentation. A "flower" is a powder that forms after the precipitate has been recovered.

22 Determine the molar mass of an unknown gas that has a volume of 72.5 mL at a temperature of 68C, and a pressure of 0.980 atm and a mass of 0.207 g.
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

Nitrogen is used to keep food frozen during transportation.
Which properties make it suitable for this?
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.
What is food packing?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.
What is bacteria?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.

Observe something through your senses or record information using scientific tools and instruments and ask questions about your scientific observations (e.g., natural phenomena).
How to calculate data involving metric units?
To convert from one unit to another within the metric system usually means moving a decimal point (e.g., 1000000mm = 100000cm = 10000dm = 1000m = 100dkm = 10hm = 1km).
