Answer: Larger proportion
Explanation:
A binary solution is made up of two components , one of which is solute and another is solvent.
A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase.
A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.
Hence, solvent is present in larger proportion.
The partial pressure of each component of the gas are:
1. The partial pressure of CH₄ is 276.48 KPa
2. The partial pressure of C₂H₆ is 27.34 KPa
3. The partial pressure of C₃H₈ is 3.38 KPa
We'll begin by calculating the mole fraction of each gas.
Percentage of CH₄ = 90%
Total = 100%
Mole fraction = mole / total
Mole fraction CH₄ = 90 / 100
Percentage of C₂H₆ = 8.9%
Total = 100%
Mole fraction = mole / total
Mole fraction C₂H₆ = 8.9 / 100
Percentage of C₃H₈ = 1.1%
Total = 100%
Mole fraction = mole / total
Mole fraction C₃H₈ = 1.1 / 100
Finally, we shall determine the partial pressure of each gas. This can be obtained as follow:
1. Determination of the partial pressure of CH₄
Mole fraction CH₄ = 0.9
Total pressure = 307.2 KPa
Partial pressure = mole fraction × Total pressure
Partial pressure of CH₄ = 0.9 × 307.2
Partial pressure of CH₄ = 276.48 KPa
2. Determination of the partial pressure of C₂H₆
Mole fraction C₂H₆ = 0.089
Total pressure = 307.2 KPa
Partial pressure = mole fraction × Total pressure
Partial pressure of C₂H₆ = 0.089 × 307.2
Partial pressure of C₂H₆ = 27.34 KPa
3. Determination of the partial pressure of C₃H₈
Mole fraction C₃H₈ = 0.011
Total pressure = 307.2 KPa
Partial pressure = mole fraction × Total pressure
Partial pressure of C₃H₈ = 0.011 × 307.2
Partial pressure of C₃H₈ = 3.38 KPa

Answer:
276.48 atm → CH₄
27.3 atm → C₂H₆
3.38 atm → C₃H₈
Explanation:
Percentages of each gas, are the mole fraction
0.9 CH₄
0.089 C₂H₆
0.011 C₃H₈
Mole fraction = Partial pressure each gas/ Total pressure
0.9 = Partial pressure CH₄ / 307.2 kPa
307.2 kPa . 0.9 = 276.48 atm
0.089 = Partial pressure C₂H₆ / 307.2 kPa
307.2 kPa . 0.089 = 27.3 atm
0.011 = Partial pressure C₃H₈ / 307.2 kPa
307.2 kPa . 0.011 = 3.38 atm
Answer : The heat released by the eater is, [/tex]
Explanation :
Formula used :
or,
where,
Q = heat released = ?
m = mass of water = 200 g
c = specific heat of water =
= initial temperature =
= final temperature =
Now put all the given value in the above formula, we get:
[/tex]
Therefore, the heat released by the eater is, [/tex]
b. neutrons
c. protons or neutrons
d. protons, neutrons or electrons
When neutrons are added to an atomic nucleus, energy is produced and this is called a fusion reaction. The answer is letter B. To be exact, two nuclei combine to produce a more stable nucleus. The positive charge on both nuclei result in a large electrostatic energy barrier to fusion.
The correct answer is c because the nuc are combing more protns and neutrons. The answer suposed to be protons and neutrons NOT PROTONS OR NEUTRONS?!!
Which letter (a-f) represents potential energy (ΔH) of the reactants?
Answer:
1) Which letter (a–f) represents potential energy (ΔH) of the products?
2) Which letter (a-f) represents potential energy (ΔH) of the activated complex?
3) Which letter (a-f) represents potential energy (ΔH) of the reactants?
Explanation:
The graph ploted represents the changes in the chemical potential (stored) energy for the reaction X + Y → Z as long as it evolves from reactants to products.
The left side of the graph shows the potential energy of the reactants, X and Y, when the reaction has not yet occurred.
Thus, the letter (a) is the potential energy of the reactants.
Moving from left to right you see that the potential energy increases, until a maximum. The maximum is when the reactants (X and y) have reacted up to an intermediate stage, in which there exists a transition state featured by an activated complex whose structure is half-way between the reactants and the products.
Thus, the letter (c) represents the potential energy of the activated complex.
At the far right of the graph, the reaction has gone to completion, the activated complex ends the transition state and the final products are formed. Thus, the letter (e) represents the potential energy of the products (Z).
All those energies are measured with respect to the same base line (the x-axis).
The attached graph has some labels added to help to identify the 3 stages: reactants, activated complex, and product.
Potential energy of products, reactants and activated complex in an energy profile diagram are displayed right end, left end and at the highest point of the diagram, respectively. However, the corresponding letters (a-f) would depend on the specific diagram.
In general, when you look at an energy profile diagram, the potential energy (ΔH) of the products is usually represented by the energy level of the products on the right side end of the diagram, which could be any of the letters a-f but depends on the specific diagram given. Similarly, potential energy (ΔH) of the reactants can be represented by the energy level of the reactants on the left end of the diagram. The potential energy (ΔH) of the activated complex, also known as the transition state, is usually the highest point on the diagram, indicating the highest energy level.
It's important to keep in mind that these are general guidelines for interpreting an energy profile diagram. The actual answer to your question (potential energy, activated complex, and reactants would depend on the specific diagram you're looking at.

(2) H2O (4) KOH
Answer: Option (B) is the correct answer.
Explanation:
According to Arrhenius, acid are the substance that produce hydrogen ions when dissolved in a solution.
For example, shows that HBr is an Arrhenius acid.
Whereas Arrhenius bases are the substances that produce hydroxide ions when dissolved in a solution.
For example, shows that KOH is an Arrhenius base.
Therefore, when an Arrhenius acid in an aqueous solution reacts with an Arrhenius base in an aqueous solution then following reaction occurs.
Thus, we can conclude that out of the given options, KBr is the product.
