A homogeneous mixture or solution consists of _____.

Chemistry
1 answer:
Fed [463]3 years ago
7 0

Answer: Option (C) is the correct answer.

Explanation:

A mixture in which the components are evenly distributed or the components are present in same proportion throughout the mixture is known as a homogeneous mixture or solution.

As a result, there exists only one phase in the mixture. The components of mixture can be in solid, liquid or gaseous form.

For example, when sodium chloride (solid phase) is added in water (liquid phase) then it completely dissolve in it. Thus, there will be no boundary between the solute and solvent. Hence, it forms a homogeneous solution.

Therefore, we can conclude that a homogeneous mixture or solution consists of substances in more than one phase.

vaieri [72.5K]

Answer:

a. Disminuye.

b. Disminuye.

Explanation:

¡Hola!

En este caso, considerando que tenemos una reacción en la cual se podría asumir que tanto la concentración de monóxido de carbono y la de oxígeno contribuye a la velocidad de reacción, de acuerdo a la siguiente cinética elemental:

r=k[CO]^2[O_2]

Al aplicar los siguientes cambios, resultaría:

a. En este caso, bien sabemos que la velocidad de reacción es aumentada al adicionar un catalizador ya que la constante de velocidad aumenta al disminuir la energía de activación; no obstante, al retirar el catalizador, la energía de activación aumentaría y por consiguiente la velocidad de reacción disminuiría.

b. En este caso, dado que la relación entre el oxígeno y la rapidez de reacción es directamente proporcional, es possible para nosotros determinar que al eliminar parte del oxígeno, la concentración disminuye y por ende la velocidad de reacción también.

¡Saludos!

As a bond between a hydrogen atom and a sulfur atom is formed, electrons are
Stels [109]
In ionic bonds electrons are transferred from one species to another and the electrostatic attraction between oppositely charged ions gives rise to the ionic bond.
covalent bonds are when electrons are shared between 2 atoms.
the electronegativity difference between the atoms taking part in the bond will decide if its an ionic bond or covalent bond.
if the electronegativity difference is very large then ionic bond is formed. if the electronegativity difference is very low then covalent bond is formed 

the electronegativity difference between H and S is very small therefore they form a covalent bond by sharing their electrons
correct answer is 
2) electrons are shared to form a covalent bond
