Are all mixtures solutions?​

Chemistry
1 answer:
marin [14]3 years ago
7 0

Answer:

Not all mixtures are solutions. A solution is a specific term that describes an even or homogeneous mixture of a solute, the substance being mixed, in a solvent, the substance that is in a greater amount in which the solute dissolves. All solutions are mixtures because it is two or more substances mixed together.

In a chemical equation, which symbol should be used to indicate that a substance is in solution?
lisov135 [29]
Example :

2FeCl_3_{(aq)}+2KI_{(aq)}=2FeCl2_{(aq)}+2KCl_{(aq)}+I_2_{(s)}

If you use the subscript (aq) (=aquaris) , this means that the substance is in a solution.

Subscripts:
-aq-this means that the substance is in a solution
-s-this means that the substance is a solid(or precipitate)
-l-this means that the substance is a liquid
-g-this means that the subtance is a gas

Mass transfer rate in convection is ..... mass transfer in conduction
lana66690 [7]

Answer:

(a) more than

Explanation:

Conduction:

Transfer of heat due to direct contact between two mediums at different temperatures, without having any of the bodies traveling. Therefore, conduction heat transfer occurs by the transfer of momentum (molecular) from always the same group of molecules in one medium to another group of molecules in another medium.

Example: Heat transfer INSIDE a solid.

Convention:

Transfer of heat or mass due to at least one traveling medium, where the transfer of momentum is not bounded anymore to the same groups of molecules. Molecules moving to transfer their momentum and keep flowing to the next group, also allowing other molecules behind to do the same. Example: heat transfer by the wind.

Hence, the Mass transfer rate in convection is <u>more than</u> mass transfer in conduction

A metal oxide reacts chemically with water to form a base in the reaction shown below. If the temperature of the metal oxide and
Alla [95]

increase the rate of chemical change.

Explanation:

The reaction of the metal oxide with water to form a base in the presence of a spike in temperature will lead to an increase in the rate of chemical change.

Temperature change has considerable effect on reaction rates.

  • Temperature is directly proportional to the average kinetic energy of reacting particles.
  • Reaction rates varies directly with a spike in temperature.
  • It has been known that for every 10°C rise in temperature, above the room temperature, reaction rates become double or tripled.
  • Temperature increases the kinetic energy of each of the reacting particles.
  • Many of the reacting particles also acquires an energy greater than or equal to the activation energy of the reaction.
  • The frequency of ordinary collisions and effective collisions per unit time increases.

1. How does the Key change for a weak acid?
Tema [17]

The weak acid will have fewer ions than the strong acid of similar concentration.

The chemical reactions for a weak acid and a strong acid is given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

<h3>What are strong and weak acids?</h3>

Strong acids are acids which dissociate completely in solutions. Examples of strong acids are hydrochloric acid and sulfuric acid.

Weak acids are acids which dissociate only partially in solutions. Examples of weak acids are carbonic acid and acetic acid.

Weak acids of a similar concentration to a strong acid have fewer hydrogen ions.

The equation of the dissociation of strong acids and weak acids are given below:

  • Strong acid: HA → H⁺ + A⁻
  • Weak acid: HA ⇆ H⁺ + A⁻

In conclusion, weak acids produce few ions in solution while strong acids fully dissociate into ions in solution.
