Imagine you created a toxin such that when a neuron fired an action potential, the toxin would bind immediately to the sodium-po
loris [4]

Answer:Maintaining resting potential and returning to resting potential after the hyperpolarization phase of an action potential

Explanation:TOXINS are chemical substances which are known to be POISONOUS produced with living organisms that causes harm to other organisms, examples include Venom from snakes which when a person is bitten by a Snake it will possibly lead to death if not adequate treated.

HYPERPOLARIZATION is a term that explains the change in membrane potential due to toxin,it make the membrane more electronegative. When the toxin has hyped the level of Sodium-Potassium level returning to a rest state will be most affected.

How would you find 8m of carbon chloride using 87.9g carbon chloride
vaieri [72.5K]

Answer:

Explanation:

I want to believe that your question is how to find an 8M carbon chloride solution using the given mass of the compound.

The problem clearly identifies with concentration of a substance. Molarity is one of the ways of expressing concentration. It is the amount of solute of a substance per volume of solution.

     Molarity  = \frac{number of moles of solute}{Volume of solution}

To find the right mix that will give us 8M carbon chloride solution, let's explore how to figure out the appropriate volume.

Clearly given is the mass of the compound, convert to number of moles.

  Number of moles  = \frac{mass}{molar mass}

            Molar mass of carbon chloride(CCl₄)  = 12 + 4(35.5)  = 154g/mol

Number of moles  = \frac{87.9}{154}   = 0.57moles

To find the volume;

            8    =    \frac{0.57}{v}

            volume = 0.071L or 71mL

What units should be used when describing the density of oil?
Alinara [238K]

Answer:

Generally, density is measured using he SI unit for measurement of density which is kg/m³ or the cgs units used to describe the density of a substance which is g/cm³

However, due to its nature (being composed of varying amount proportions of different compounds mixed together resulting in a variation of the density of naturally produced crude oil) of having different densities whereby the lighter oils are more easily processed than the heavier variety of oils, oil density is related to the quality of the oil and it is usually measures in API gravity as follows;

°API = (141.5/S.G.) - 131.5

Where;

API = American Petroleum Institute

S. G. = Specific gravity

As such the API gravity of fresh water with a S. G. of 1.0 has is 10 degrees
