The answer is B (breaking it apart) because factors such as surface area increase the likelihood of particle collisions and the reaction rate. Other factors are pressure, temperature, concentration, and surface.

Answer: Option (b) is the correct answer.

Explanation:

One of the best way to increase the speed of particles in a solid mass is that increasing the surface area. This can be done by breaking the solid mass into various particles.

Due to this there will be increase in number of particles and as a result, it will lead to more number of collisions. Hence, there will be increase in rate of a reaction.

Thus, we can conclude that action of breaking it apart will allow Mora to increase the speed of particles.

We describe the regeneration of the action potential down the membrane of the axon of the neuron as _______.
Sunny_sXe [5.5K]
The regeneration of the action potential inside the membrane of the neuron's axon is called the hyperpolarization conduction or propagation conduction. Hyperpolarization takes place when the membrane of the cell is in a negative charge. It therefore stimulates action potentials to increase its stimulus.

Gasoline and kerosene (specific gravity 0.820) are blended to obtain a mixture with a specific gravity of 0.770. Calculate the v
Dmitrij [34]

Answer:

The volumetric ratio is 0,71

Explanation:

Let's begin with the equation:

Db = Mb/Vb (1)

Where:

Db: Blend Density, Mb: Blend Mass and Vb: Blend Volume

And we know: Vb = Vg + Vk (2)

Where:

Vg: Gasoline Volume and Vk: Kerosene Volume

Therefore replacing (2) into (1):

Db = (Mg + Mk) / (Vg + Vk)

Db = (Dg * Vg + Dk * Vk)/(Vg + Vk) (3)

Where:

Dg: Gasoline Density and Dk: Kerosene Density

The specific gravity is defined as:

SG = Substance Density / Reference Density

Therefore:

Db = SGb * Dref\\Dg = SGg * Dref\\Dk = SGk * Dref

Where:

Dref: Reference Density

SGb: Blend Specific Gravity

SGg: Gasoline Specific Gravity (which is 0.7 approximately)

SGk: Kerosene Specific Gravity

Replacing these equations into (3) we get:

SGb * Dref = (SGg * Dref * Vg + SGk * Dref * Vk)/(Vg + Vk)

SGb * Dref = Dref * (SGg * Vg + SGk * Vk)/(Vg + Vk)

SGb = (SGg * Vg + SGk * Vk)/(Vg + Vk)

SGb * (Vg + Vk) = SGg * Vg + SGk * Vk

SGb * Vg + SGb* Vk = SGg * Vg + SGk * Vk

Replacing with the Specific Gravity data, we obtain:

0.77 * Vg + 0.77 * Vk = 0.7 * Vg + 0.82 * Vk

0.77 * Vg - 0.7 * Vg = 0.82 * Vk - 0.77 * Vk

0.07 * Vg = 0.05 * Vk

Vg/Vk = 0.05/0.07

Vg/Vk = 0.71

If you have the equation
garri49 [273]
Assuming the conditions of the reaction are maintained and appropriate for the reaction to still occur, the reaction rate can be affected by increasing the concentration of the reagents used in a reaction. It will speed it up.
