In two or more complete sentences, compare singe displacements reactions and double displacement reactions

Chemistry
1 answer:
vodomira [7]3 years ago
4 0

Answer:

The answer is in the explanation

Explanation:

Single displacement reactions: In these reactions, a more reactive element kicks out a less reactive element from a compound.

Ex.  Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)

In this example, Zn is more reactive than H, then Zn displaces H from the compound.

Double displacement reactions: In these kind of reactions 2 elements are displaced from the different compounds, these elements interchange positions.

Ex. CuCl2(aq) + 2 AgNO3(aq) → Cu(NO3)2(aq) + 2 AgCl(s)

In the example, Cu displaces Ag and Ag displaces Cu, they interchange positions.

Cups and glasses are taking too long to air dry this could be caused by
lions [1.4K]

Cups and glasses are taking too long to air dry this could be caused by the bad ventilation system.

Bad ventilation, or the lack of air flow.

To make sure that no moisture is left on them.

If the moisture or some water drops are left on glasses or cups.

These water drops leave a strange mark and causes a smell in dishes.

Other reasons of cups and glasses are taking too long to dry than the improper working of ventilation can be:

Humidity in Air, Improper Heat, and use of Soap

Humidity in Air, causes high moisture in air that results in the delay in drying of dishes that may lead to even bad smell and bacterial infection on cups and glasses causing bad health.

What is the price coke difference between a strong and weak acid?
KATRIN_1 [288]

Explanation:

Strong acids are those that are completely ionized in body fluids, and weak acids are those that are incompletely ionized in body fluids. Hydrochloric acid (HCl) is considered a strong acid because it is present only in a completely ionized form in the body, whereas carbonic acid (H2 CO3) is a weak acid because it is ionized incompletely, and, at equilibrium, all three reactants are present in body fluids. See the reactions below.

H2 CO3 (acid)↔H+ + HCO3- (base)

I need help with this one pls, ty! ASAP
LuckyWell [14K]

Answer:

Explanation:

1. A measure of how quickly velocity is changing is the acceleration

Acceleration is the rate of change of velocity with time. The rate at which a body is changing its velocity is known as the acceleration.

It is measured in the unit m/s²

2. Speed in a given direction is the velocity

Velocity is a vector quantity which measures the magnitude of motion in a specific direction. It is simply speed in a given direction.

When we say a motorcycle travels at the rate of 5m/s due east, we are describing the velocity of such body.

3. Force that resists moving one object against another is the friction

Friction is a force that opposes motion. It prevents a body from moving.

4. Measure of the pull of gravity on an object Weight

Weight is a measure of the amount of gravitational force on a body. It is mathematically expressed as;

         W = mg

W is the weight, m is the mass and g is the acceleration due to gravity

5 Tendency of an object to resist a change in motion is inertia

Inertia is the tendency of body to resist change in motion. It is the ability of a body to remain in a perpetual state of rest.

6 Size is the magnitude
