Child A runs at 4.1667 meters per second and child B runs at 3.048 meters per sec. If they do not slow down Child A will be able to catch child B.
Answer:
- <u><em>The first statement is false: a.At equilibrium, equal amounts of products and reactants are present. ΔG° is a function of Keq.</em></u>
Explanation:
When one part of a statement is false, the whole statement is false.
At <em>equilibrium,</em> the amounts of products and reactants does not have to be equal.
At equlibrium the rates of the forward reaction and the reverse reaction must be equal.
An equilibrium reaction may be represented by:
That represents two reactions:
- Direct reaction: A + B → C + D (A and B yield C and D)
- Reverse reaction: A + B ← C + D (C and D yield A and B: note that the arrow goes from right to left)
So, it is when the direct and the forward rates are equal that there is not net change in the amounts of all the species and so the reaction is is equilibrium).
As per the other statement, both parts are true:
- When reactants become products, they do so through an intermediate transitrion state: when the reactants approach each other and collide with enough energy and appropiate position, the bonds start to break and the bonds of the products start to form. This is the transition state.
- Most biocatalysts are proteins: enzymes are simply proteins, with specific structures, that may accelerate or even deceralate biochemical reactions.
Orbital hybridization (or hybridization) is the concept of mixing atomic orbitals to form new hybrid orbitals (with different energies, shapes, etc., than the component atomic orbitals) suitable for the pairing of electrons to form chemical bonds in valence bond theory.
<h3>What types of hybrid orbitals are?</h3>
The five basic shapes of hybridization are linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral. The geometry of the orbital arrangement: Linear: Two electron groups are involved resulting in sp hybridization, the angle between the orbitals is 180°.
<h3>Why are hybrid orbitals formed?</h3>
Hybridization occurs when an atom bonds using electrons from both the s and p orbitals, creating an imbalance in the energy levels of the electrons. To equalize these energy levels, the s and p orbitals involved are combined to create hybrid orbitals.

Answer:
F = -5.91 E-10 N
Explanation:
The force of attraction between the ions Ca²⁺ and O²⁻ is given by the Coulomb's Law:
![F = K \frac{q_{1}q_{2}}{r^{2}}](https://tex.z-dn.net/?f=%20F%20%3D%20K%20%5Cfrac%7Bq_%7B1%7Dq_%7B2%7D%7D%7Br%5E%7B2%7D%7D%20)
<em>where K: is the Coulomb's constant, q₁ and q₂: are the charges of the electrons (e = 1.602E-19 C) of the ions, and r: is the distance between the charges. </em>
<u>With q₁ = charge of Ca = (2+)(1.602E-19 C), q₂ = charge of O = (2-)(1.602E-19 C), K= 9E09 N.m².C⁻² and r = 1.25nm = 1.25 E-09 m, the force of attraction between the ions is:</u>
Therefore, the force of attraction between a Ca²⁺ ion and O²⁻ ion is -5.91 E-10 N.
