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.

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.

Protons are a subatomic particle. Which description below accurately describes a proton's charge, location, and mass?
a) A proton is in the nucleus, has no charge, and atomic mass of 1 amu.
b) A proton is outside the nucleus, has a negative charge, and is so small it doesn't contribute to the mass.
c) A proton is in the nucleus, has a positive charge, and an atomic mass of 1 amu.
d) A proton is outside the nucleus, has a positive charge, and is so small it doesn't contribute to the mass.
Answer: C) a proton is in the nucleus, has a positive charge, and an atomic mass of 1 amu.
Explanation:
Protons are positive so they give a positive charge, they are also never outside of the nucleus. Only electrons are outside the nucleus.

Water forms according to the equation below: 2H2(g) + O2(g) 2H2O(g) Hrxn = -483.64 kJ How much energy is released during the formation of 1 mol H2O(g)?
Answer:
Hrxn = -241.82 kJ
Explanation:
2H2(g) + O2(g) --> 2H2O(g) Hrxn = -483.64 kJ ............. (i)
The equation for formation of 1 mol of H2O is given as;
H2(g) + 1/2O2(g) --> H2O(g) ................. (ii)
Eqn (ii) is obtained by dividing eqn (i) by 2
That means the heat of reaction for eqn (ii) is given as;
Hrxn = -483.64 kJ / 2
Hrxn = -241.82 kJ
Answer:-241.82 kJ

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.

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.

2. How much heat is needed to convert 2.7 moles of ethanol at its boiling
point from liquid to vapor?
Answer:
así que busca, pero la respuesta está en por cierto Explanation:
The quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ
From the question,
We are to calculate the heat needed to convert 2.7 moles of ethanol from liquid to vapor.
Using the formula
Q = n × ΔHvap
Where Q is the quantity of heat
n is the number of moles
and ΔHvap is the enthalpy of vaporization
From the given information,
n = 2.7 moles
and
ΔHvap of ethanol = 38.7 kJ/mol
Putting the parameters into the formula, we get
Q = 2.7 × 38.7
Q = 104.49 kJ
Hence, the quantity of heat needed to convert 2.7 moles of ethanol at its boiling point from liquid to vapor is 104.49 kJ
