The accounts for the difference between curve A and curve B on the energy diagram is the reaction described by curve B is occurring with a catalyst. Therefore, option D is correct.
What is an energy diagram ?An energy profile is a theoretical representation of a chemical reaction or process as a single energetic pathway that transforms reactants into products.
The amount of relative potential energy in each step of a reaction is depicted by an energy diagram. Reactants, transition states, and products are typically depicted on energy diagrams. It may also include intermediates and activation energy, depending on the reaction.
An energy diagram depicts how an object's potential energy varies with position and provides information about the object's motion.The potential energy curve depicts the amount of potential energy that the boulder has at each position.
Thus, option D is correct.

help help plz what is the difference between normal and transition elements
Answers
Answer:
hope it helps you
mark me as brainliest!!
However, a transition element is an element which belongs to the d-block of the periodic table i.e, from group 3 to group 12.
It is called as a transition element because it is between the s-block and the p-block elements. There is a transition from the s-block to the p-block where s-block has metals and p-block has non-metals. So the block between these 2 is called the transition block which consists of the transition elements since there is a transition from metals to non-metals.
Normal elements includes both metals and non metals where as transition elements are only metals
Normal elements have their only last shell incomplete wherese transition have last two shells incompletely filled.
Normal elements are placed on the side of the periodic table whereas transition elements are at the middle of the periodic table.
A certain electromagnetic wave a wavelength of 415 nm. What is the frequency of the wave in hz?
Answers
Answer:
The frequency of the electromagnetic wave is 7.22891566 × 10¹⁴ Hz
Explanation:
The wavelength of the electromagnetic wave, λ = 415 nm
The speed of an electromagnetic wave, c ≈ 3.0 × 10⁸ m/s
Given that an electromagnetic wave is a periodic wave, we have;
The speed of the electromagnetic wave, c = f×λ
Where;
f = The frequency of the electromagnetic wave
Therefore, we have;
f = c/λ
From which we have;
f = (3.0 × 10⁸ m/s)/(415 nm) = 7.22891566 × 10¹⁴ /s = 7.22891566 × 10¹⁴ Hz
The frequency of the electromagnetic wave, f = 7.22891566 × 10¹⁴ Hz

From the question given above, the following data were obtained:
Number of molecules = 12.06×10²²
Number of mole =?
From Avogadro's hypothesis,
6.02×10²³ molecules = 1 mole
Therefore,
12.06×10²² molecules = 12.06×10²² / 6.02×10²³
12.06×10²² molecules = 0.2 mole
Thus, 12.06×10²² molecules is equivalent to 0.2 mole

The second law is Charles's law that states that at constant pressure, the volume of the gas is directly proportional to the temperature of the gas.
Above, both laws form the ideal gas law. PV = nRT.

Cell 5: Mn(s) | Mn(NO3)2 (aq) || Zn(NO3)2(aq) | Zn(s)
Remember to use proper formatting and notation.
Answers
Answer:
Cathode: Mn → Mn²⁺ + 2e⁻ (Oxidation)
Anode: Zn²⁺ + 2e⁻ → Zn (Reduction)
Mn | Mn²⁺ || Zn²⁺ | Zn
Explanation:
To identify the half reaction we need to see the oxidation states.
Mn(s) → Ground state → Oxidation state = 0
Mn(NO₃)₂ → Mn²⁺ → The oxidation state has increased.
This is the oxidation reaction. It has released two electrons:
Mn → Mn²⁺ + 2e⁻
Zn(NO₃)₂ → Zn²⁺
Zn → Ground state → The oxidation state was decreased.
This is the reduction reaction. It has gained two electrons:
Zn²⁺ + 2e⁻ → Zn
Cathode: Mn → Mn²⁺ + 2e⁻
Anode: Zn²⁺ + 2e⁻ → Zn
Mn | Mn²⁺ || Zn²⁺ | Zn

1. Dynamic equilibrium is a equilibrium in which the rate of forward direction is equal to the rate of backward direction. It is represented by a right left arrow.
2) Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as [tex]K_c[/tex]
For the given chemical reaction:
[tex]Fe^{3+}(aq)+SCN^-(aq)\rightleftharpoons [Fe(SCN)]^{2-}(aq)[/tex]
The expression for [tex]K_c[/tex] is written as:
[tex]K_c=\frac{[[Fe(SCN)]^{2-}]}{[Fe^{3+}][SCN^-]}[/tex]
3) The value of [tex]K_c[/tex] is 1000 , which means the products are more favoured as compared to reactants and that the equilibrium lies more towards product side.
