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.
Thus, If one have 10 pieces of bread, 4 tablespoons of peanut butter, and 20 tablespoons of jelly, the limiting reactant will be peanut butter.

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 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.

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.
why the iron nail not rusted on a chemical to absorb water vapour
Answer:
Thus there was no accumulation of ions on the nails, as the dissolved gases were already removed, hence no rust formation. In test tube C, a chemical was added to absorb the water vapour. We know that rust formation takes place when a metal is exposed to water vapour.

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.
How many grams of oxygen are produced when 3.0 moles of potassium chlorate decompose completely?
The mass of oxygen produced when 3.0 moles of potassium chlorate decomposed completely is 144 g
Equation for the reactionWe'll begin by writing the balanced equation for the reaction. This is given below:
2KClO₃ —> 2KCl + 3O₂
From the balanced equation above,
2 moles of KClO₃ decomposed to produce 3 moles of O₂.
How to determine the number of mole of oxygen produced.From the balanced equation above,
2 moles of KClO₃ decomposed to produce 3 moles of O₂.
Therefore,
3 moles of KClO₃ will decompose to produce = (3 × 3) / 2 = 4.5 moles of O₂.
How to determine the mass of oxygen produced Molar mass of O₂ = 2 × 16 = 32 g/mol Mole of O₂ = 4.5 moles Mass of O₂ =?
Mass = mole × molar mass
Mass of O₂ = 4.5 × 32
Mass of O₂ = 144 g

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.
