If the air from the problem above contains 22% oxygen, 75% nitrogen and 3% argon, what is the partial pressure of oxygen near a blast furnace in mmHg?
Assuming the total pressure is 1 atm, the partial pressure of oxygen is 0.22 atm.
What is the partial pressure of oxygen if air contains 22% oxygen, 75% nitrogen and 3% argon?The partial pressure of a gas in a mixture of gases is calculated using the formula below:
Partial pressure of a gas = mole fraction/total pressureAssuming:
the total pressure is 1 atm.mole fraction of oxygen = 22% = 0.22Partial pressure of oxygen = 0.22/1
Partial pressure of oxygen = 0.22 atm.

A paragraph on information about density.
Answer:
Density is a measure of mass per unit of volume. ... The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water).
True or false. It is safe to heat flammable liquids with a hot plate as long as it’s done in a fume hood.
Answer:
The answer is false
It is safe to heat flammable liquids with a hot plate as long as it’s done in a fume hood. The above statement is false.
What is flammable liquids?A flammable liquid is one with a flash point at or below the nominal threshold temperatures specified by a variety of national and worldwide standards organizations. This means that it can easily ignite in air at room temperature.
Acetone, biodiesel, diesel, ethanol, and gasoline are just a few examples of flammable liquids. Strict storage regulations must be followed since the fumes of these substances rapidly catch fire and burn. These liquids are even further divided into groups based on their flash points or boiling points, and it is from these groups that safe handling and storage procedures are determined. It is not safe to heat flammable liquids with a hot plate as long as it’s done in a fume hood.
Therefore, the given statement is false.

Which is an example of variations in a population of organisms
Answer:
The gravitational potential energy it had from being above the ground is converted to kinetic energy as the rock falls. As kinetic energy increases, the velocity of the rock will also increase. However, if one considers the air, the rock will lose energy as it falls due to air resistance. If the cliff is high enough, the acceleration due to gravity and the air resistance due to the velocity will be exactly equal and there will be no change in kinetic energy.

How many moles of hydrogen are in 3. 06 × 10⁻³ g of glycine , c₂h₅no₂?.
Answer:
n = 6.06 x [tex]10^{-4}[/tex] mol
Explanation:
n =?
m = 3.06 x 10-³ g
M (H5) = 5 x 1.01 (Since we only want hydrogen)
Atomic mass of C = 12.01
Atomic mass of H is 1,01, etc.
Having this data, we can use the Molar mass formula and change it so we can know the quantity of matter (n) in moles, and we just replace it.
M = [tex]\frac{m}{n}[/tex] ⇔ n = [tex]\frac{m}{M}[/tex] ⇔ n = [tex]\frac{3.06 x 10^{-3} }{5,05}[/tex] ⇔ n = 6.06 x [tex]10^{-4}[/tex] mol

If you evaporated 125 mL of a 3.5 M solution of iron(II) nitrite, how many moles of iron(II) nitrite would you recover?
If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.
What is molarity?Molarity is a measure of the concentration of a chemical species, in particular of a solute in a solution, in terms of moles of solute per liter of solution.
We want to find the moles of iron (II) nitrite (solute) in 125 mL of a 3.5 M solution. We will use the definition of molarity.
M = n / V(L)
n = M × V(L) = 3.5 mol/L × 0.125 L = 0.438 mol
where,
M is the molarity.n is the number of moles.V(L) is the volume of the solution in liters.If 125 mL of a 3.5 M solution were evaporated, 0.438 moles of iron (II) nitrite would be recovered.

Which substance is composed of atoms that all have the same atomic number
A). Ethane
B). Ethene
C). Methane
D). Magnesium
Answer:
D. Magnesium
Explanation:
The substance is composed of atoms that all have the same atomic number C) Methane. Methane (CH₄) is composed of atoms that all have the same atomic number. In this case, all the atoms in methane are hydrogen atoms, each having an atomic number of 1.
Atoms are the basic building blocks of matter. They are the smallest units of an element that retain the chemical properties of that element. Atoms consist of three main subatomic particles.
The number of protons in an atom determines its atomic number and identifies the element. For example, an atom with 6 protons is carbon, and an atom with 8 protons is oxygen.
Atoms are electrically neutral overall because the number of protons is equal to the number of electrons. However, atoms can gain or lose electrons to form ions, which have a net positive or negative charge.
Ethane (C₂H₆) and ethene (C₂H₄) contain both carbon and hydrogen atoms, while magnesium (Mg) is an element itself and consists of atoms with atomic number 12. Therefore, the substance is composed of atoms that all have the same atomic number C) Methane.
