How many L of a 7.5 H2SO4 stock solution would you need to prepare a dilute solution 100 L of 0.25M H2SO4
Answer:
3.33 L
Explanation:
We can solve this problem by using the equation:
C₁V₁=C₂V₂Where the subscript 1 refers to one solution and subscript 2 to the another solution, meaning that in this case:
C₁ = 0.25 MV₁ = 100 LC₂ = 7.5 MV₂ = ?We input the data:
0.25 M * 100 L = 7.5 M * V₂V₂ = 3.33 LThus the answer is 3.33 liters.

Answer:
Mitochondria
Explanation:
Glucose in an energy molecule contained in carbohydrate food substances. The end product of the digestion of carbohydrate is glucose which is broken down to produce energy.
The sequence of breakdown of glucose is as follows; In the first step, 6-carbon glucose is broken down into two molecules of 3-carbon pyruvic acid. This occurs in the cytoplasm of the cell. It is an anaerobic process.
In the second step which occurs in the mitochondrion, each of the molecules of pyruvic acid is now oxidized to carbon dioxide and water and energy is produced in the process.

How many moles of PbCl2 are produced
if 14 moles of AlCl3 are consumed?
3Pb(NO3)2 + 2AlCl3 + 3PbCl2 + 2A1(NO3)3
Answer:21 moles of PbCl2 formed
Explanation: 3Pb(NO3)2(aq) + 2AlCl3(aq) --> 3PbCl2(s) + 2Al(NO3)3(aq)
14 moles AlCl3 x 3 moles PbCl2/2 moles AlCl3 =21 moles of PbCl2 formed
The number of moles of PbCl₂ produced when 14 moles of AlCl₃ are consumed in the reaction is 21 moles
Balanced equation3Pb(NO₃)₂ + 2AlCl₃ —> 3PbCl₂ + 2Al(NO₃)₃
From the balanced equation above,
2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.
How to determine the mole of PbCl₂ producedFrom the balanced equation above,
2 moles of AlCl₃ reacted to produce 3 moles of PbCl₂.
Therefore,
14 moles of AlCl₃ will react to produce = (14 × 3) / 2 = 21 moles of PbCl₂.
Thus, 21 moles of PbCl₂ were obtained from the reaction.

gold has a density of 19.32 g/cm3 if you cut a piece of gold in half how much will the density of each piece be?
Answer:
19.32 g/cm³
Explanation:
The density will remain the same no matter how many times you cut the gold. The density is g/cm³ or g/mL. Density is essentially how many grams 1 mL of a compound weighs.
Answer:
[tex]\boxed {\boxed {\sf 19.32 \ g/cm^3}}[/tex]
Explanation:
Density is the mass per volume (g/mL or g/cm³). It is an intrinsic property. This means it is not dependent on the amount and all samples of the same substance have the same density.
Therefore, if a piece of gold has a density of 19.32 grams per cubic centimeter and it is cut in half, the two pieces will have the same density.

Iron is extracted from its ore (hematite) in the blast furnace. Which gas is produced as a waste product?
Answer:
CO2
Explanation:
CO2 or carbon dioxide is produced when iron is extracted from its ore. Carbon monoxide Co is used as reducing agent in iron extraction. In this reaction iron ore is reduced to iron and CO is oxidized to CO2 or carbon dioxide which is released in the process. There extraction of iron is redox reaction.
Around what pH are most of the substances in your body? Why?
Answer:
The pH scale measures how acidic or alkaline — basic — something is. Your body works constantly to carefully control pH levels of blood and other fluids. The body's pH balance is also called the acid-base or acid-alkaline balance. The right pH levels are needed for good health.

The diagram shows the different models of the atom that eventually led to the modern atomic theory.
Which model was proposed as a result of Rutherford's scattering experiment where positive particles did not pass straight through a foil as expected? (5 points)
Model A
Model B
Model C
Model D
Answer:
B.
Explanation:
The atomic model represents the position of the sub-atomic particles. Model A was proposed after Rutherford's scattering experiment where the positive particles were deflected in the middle. Thus, option A is correct.
What was Rutherford's atomic model?Rutherford's atomic model proposed the presence of the positive nucleus in the middle of the atom while the electrons surrounded them in their orbitals with a negative charge.
He performed the scattering experiment where alpha particles emitted by the radioactive element were used to locate the positions of the electrons, neutrons, and protons.
According to the experiment, model A, best fits as the nucleus made of protons and neutrons takes the center of the atom with negative electrons surrounding them. The nucleus is small as compared to the entire atom.
Therefore, option A. model A best proposes Rutherford's model.

You need 2 pieces of bread, 1 tablespoon of peanut butter and 2 tablespoons of jelly to make a
sandwich. If you have 10 pieces of bread, 4 tablespoons of peanut butter and 20 tablespoons of jelly,
what is the limiting reactant?
Answer:
peanut butter
Explanation:
because you have 10 pieces of bread, 4 tbs of peanut butter, and 20 tbs of jelly, meaning you can make 5 sandwwitches with the bread, 4 sandwitches with the peanut butter, and 10 sandwitches with the jelly. so you dont have enough peanut butter to make all the sandwitches
According to the given scenario, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.
What is a limiting reactant?
The reactant that gets consumed first in a chemical reaction and result in limiting the formation of product is referred to as a limiting reactant.
According to the given scenario, the quantity of peanut butter will get consumed first so it will act as a limiting reactant.

Red is dominant to white for flower color in a particular plant. If a red flowered plant (RR) is crossed with a white flowered plant (rr), what color will the offspring be?
Answer:
The offspring will all have red-colored flowers
Explanation:
A dominant character is one that is always expressed when it is present.
A recessive character or trait is one that is only expressed in the absence of the dominant character. Thus, when the dominant and recessive character are both present in an organism, the recessive character will be hidden while the dominant character will be expressed.
According to Menedel's laws of inheritance, in the cross between the dominant (RR) red-flowered plant and the recessive (rr) white-flowered plant, the genotype of the offspring will be as follows:
RR x rr = Rr, Rr, Rr,Rr
The offspring are all heterozygous for flower color. However, since red flower color is dominant over white flower color, all the offspring produced will have red-colored flowers.

Explanation:
At what temperature would the volume of a gas be equal to 45.7 L, if the volume of that gas was 33.9 L at 12.4ºC? 241.9 K 241.9 K 451.2 K 451.2 K 384.7 K 384.7 K 273.15 K
Answer:
The temperature will be 384.7 K
Explanation:
Charles's Law consists of the relationship that exists between the volume and the temperature of a certain quantity of ideal gas, which is maintained at a constant pressure, by means of a constant of proportionality that is applied directly. For a given sum of gas at a constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases because the temperature is directly related to the energy of the movement of the gas molecules. .
In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
[tex]\frac{V}{T} =k[/tex]
Having an initial state 1 and a final state 2, the following is true:
[tex]\frac{V1}{T1} =\frac{V2}{T2}[/tex]
In this case:
V1= 33.9 LT1= 12.4 C= 285.4 K (being 0 C= 273 K)V2= 45.7 LT2= ?Replacing:
[tex]\frac{33.9 L}{285.4 K} =\frac{45.7 L}{T2}[/tex]
Solving:
[tex]T2=45.7 L*\frac{285.4 K}{33.9 L}[/tex]
T2= 384.7 K
The temperature will be 384.7 K
