The volume of HCl is needed to completely neutralize is 81.25 ml.
Formula of neutralization, M₁V₁ = M₂V₂
M₁ = concentration of HCl
V₁ = volume of HCl
M₂ = concentration of NaOH
V₂ = volume of NaOH
Put the value in M₁V₁ = M₂V₂
0.100 × V₁ = 25 × 0.325
V₁ = 25 × 0.325/ 0.100
V₁ = 81.25 ml
Hence, the volume of HCl is 81.25 ml.
In chemistry, neutralization or neutralization is a chemical reaction wherein acid and a base react quantitatively with every other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present inside the answer.

For electricity generation, the three major parts of energy are fossil fuels (coal, natural gas, and petroleum), nuclear energy, and renewable power sources.
How is electricity generated in the United States?According to the US Energy Information Administration, natural gas, nuclear energy, and coal will generate the majority of the country's electricity in 2020. Renewable energy sources such as wind, hydropower, solar power, biomass, wind, and geothermal are also used to generate electricity. In contrast to the use of fossil fuels, renewable electricity generation in the United States has increased in recent years, reaching nearly 800 terawatt hours in 2020. Natural gas, solar, and wind power continue to be the dominant forms of new generation capacity, accounting for 99.74% of all capacity additions in 2021 and 98% of capacity additions in 2022.

EASY CHEMISTRY QUESTIONS FOR 100 POINTS
Answer:
Can't decide, Can't decide, and mixture.
Hopefully this is right. Technically you also can't decide on C but the chances of it being a pure substance are very low.
Explanation:
Technically, you can't decide on any of them since you have no idea of the actual compositions. Even if the ratio of the elements in grams are the same, there is no guarantee that the elements are chemically combined. For example, if you are given the info that a box contains 1 gram of hydrogen and 8 grams of oxygen, it could contain 9 grams of water, or 1 gram of hydrogen gas and 8 grams of oxygen gas. Knowing that water contains 1 gram of hydrogen and 8 grams of oxygen per 9 grams of oxygen doesn't help you determine if a container with 2 grams of hydrogen and 8 grams of oxygen has hydrogen peroxide or just a mix of the two gasses.
For A, it could be a pure substance since the ratio of E1 to E2 is twice the ratio of E1 to E2 in substance X. You can't really decide though
For B, it could be a pure substance since the ratio of E1 to E2 is four times the ratio of E1 to E2 in substance X. You can't really decide though
For C, It is very likely to be a mixture, since the ratio of E1 to E2 in substance C is 2.7 times that of the ratio of E1 to E2 in substance X

What does molar mass mean?In chemistry, the molar mass of a chemical compound is determined by dividing its mass by the quantity of the material, or the number of moles in the sample, expressed in moles. A substance's molar mass is a bulk attribute, not a molecular one. Mass per mole is one way to define molar mass. Molar mass is, in other words, the total mass of all the atoms in a substance that makes up a mole. It is quantified in grams per mole.
Molar mass is shown for substances or molecules. The molar mass of a single element or atom would simply be that element's mass represented in atomic mass units.

What is the net ionic equation for Fe(NO3)3+3NaOH=Fe(OH)3+3NaNO3
The three rules for writing net ionic equations are actually quite simple. Consider only breaking up the (aq) substances. Only strong electrolytes should be broken up. Any ions that appear on both sides of the equation should be removed.
What exactly is a net ionic equation?A net ionic equation is defined as an equation that depicts only the molecules or ions that are actively involved in the reaction or those that change. The spectator ions are not present in this equation. First, write and balance the molecular equation, ensuring that all formulas are correct. Then, using all aqueous substances as ions, write the ionic equation. Carry any coefficients through. Finally, remove spectator ions from the equation and write the net ionic equation.

How much heat does it take to raise the
temperature of 225 g of water from 25.0°C to 100.0°C?
Answer:
7.06 x 10⁴ J
Explanation:
To find the amount of heat necessary to heat the water, you need to use the following equation:
Q = mcΔT
In this equation,
-----> Q = heat (J)
-----> m = mass (g)
-----> c = specific heat capacity (J/g°C)
-----> ΔT = change in temperature
The specific heat capacity of water is 4.186 J/g°C. You can plug the given values into the equation and simplify to find "Q".
Q = ? J c = 4.186 J/g°C
m = 225 g ΔT = 100.0°C - 25.0°C = 75.0°C
Q = mcΔT <----- Given equation
Q = (225 g)(4.186 J/g°C)(75.0°C) <----- Insert values
Q = 7.06 x 10⁴ J <----- Multiply

The average atomic mass of rubidium is 85.466 amu.
For calculating the average atomic mass of the Rb, the atomic masses for both isotopes are taken into consideration.
The [tex]^{85}{Rb[/tex] has atomic mass = 84.912 amu
The abundance of [tex]^{85}{Rb[/tex] = 72.17 %
The average atomic mass of [tex]^{85}{Rb[/tex] = 72.17 %
The average atomic mass of [tex]^{85}{Rb[/tex] =[tex]84.912\times\frac{72.17}{100}[/tex]

Calculate the mass of iron(III) oxide (Fe₂O3) that contains a billion (1.0 × 10^9) oxygen atoms.
Be sure your answer has a unit symbol if necessary, and round it to 2 significant digits.
The balanced chemical equation for rusting iron is:
4Fe + 3O2 = 2Fe2O3
If we divide 1.0x10^9 by Avogadro's number, we get the amount of moles of oxygen which is 1.6611x10^-15 moles.
From the chemical equation we know that it takes 3 moles of oxygen to produce 2 moles of iron oxide. So if we multiply the moles of oxygen calculated by 2/3, we can get the moles of iron oxide.
(1.611x10^-15)(2/3) = 1.107419x10^-15 moles of iron oxide.
If we multiply the moles of iron oxide by the molar mass of iron oxide, we get how many grams of iron oxide would be produced by 1 billion oxygen atoms. Which is the same thing as how many grams of iron oxide contain 1 billion oxygen atoms.
(1.107419x10^-15)(159.69) = 1.8x10^-13 grams of Fe2O3
In the near-vacuum of space, bare metal surfaces on the International Space Station can reach temperatures above 260°C. Why?
A. The side of the station facing the sun receives thermal energy via electromagnetic radiation.
B. As the station travels through space, a few atoms per second impact the surfaces and transfer their energy to them via conduction.
C. The heat is transferred to the surfaces by convection as the station moves through the thin fluid of space.
D. The side of the station facing deep space absorbs thermal energy radiated from all the stars on that side.
In the International Space Station on near-vacuum space, the bare metal surfaces can reach temperatures above 260℃ as the side of the station facing the sun receives thermal energy via electromagnetic radiation (A).
Space is nearly vacuum i.e., it has no air in space. Conduction and convection of heat requires air. As space is nearly vacuum, conduction and convection of heat does not happen on bare metal surface on International Space Station.

Based on the given relative atomic masses of the isotopes, the mass of Na-22 contained in this sample is 0.086 g.
What is the relative atomic mass of an element?The relative atomic mass of an element is the average mass of one mole of an atom of an element calculated from the atomic masses of the atoms of an element and their relative abundances.
relative atomic mass of an element = sum of atomic mass * relative abundance of each isotope.Isotopes of elements are atoms of an element that differ from each other by their masses. The difference in the mass of the isotopes is a result of the difference in the number of neutrons contained within the nucleus of the atoms of the isotopes.
Considering the naturally occurring sodium isotope, Na-23, and the synthetic, radioactive isotope of sodium, Na-22:
the relative atomic mass of Na-23 = 22.9898 u
the relative atomic mass of Na-22 = 21.9944 u.
mass of sample = 2.4698 g
the apparent atomic mass of the isotope = 22.9551 u
Sum of the relative abundances = 1
Let relative abundance of Na-22 = x
relative abundance of Na-22 = 1 - x
22.9898 * (1 - x) + 21.9944 * x = 22.9551
22.9898 - 22.9898x + 21.9944x = 22.9551

What is spectrophotometry?Spectrophotometry is an analytical technique that is used to measure the concentration of a solution by measuring how much light the solution absorbs or transmits when a beam of light of a given wavelength is passed through it.
In spectrophotometry, the concentration of a solution is directly proportional to its absorptivity. This implies that the higher the concentration of a solution, the higher the amount of light absorbed by the solution.
The absorptivity of the solution is inversely proportional to the transmissivity of the solution.
