Describe the neutral signaling pathway
galina1969 [7]

Answer:

A neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable a signal to be sent from one region of the nervous system to another. Neurons are connected by a single axon, or by a bundle of axons known as a nerve tract, or fasciculus.

How many grams of C8H18<br> is in 405,576.398 mL
nevsk [136]

Molarity X \frac{0.762 mol}{05.576398 L} = Mass is the of C_8H_1_8 is in 405,576.398 mL.

<h3>What is molarity?</h3>

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.

Given data:

Molar mass of  C_8H_1_8 = 0.762 mol

Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L

Solution:

Step 1: Calculating  moles of C_8H_1_8

• Molarity =\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}

• Putting the value in the given formula

• Moles of solute C8H18 = \frac{\;Mass}{\;Molar \;molar \;mass}

• Moles of solute C8H18 = \frac{\;Mass}{0.762 mol}

Now,

Molarity =\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}

Molarity =\frac{\frac{\;Mass}{0.762 mol}}{\;Volume \;of \;solution \;in \;litre}

Molarity =\frac{\frac{\;Mass}{0.762 mol}}{405.576398 L}

Molarity X \frac{0.762 mol}{05.576398 L} = Mass

Hence, Molarity X \frac{0.762 mol}{05.576398 L} = Mass is the of C_8H_1_8 is in 405,576.398 mL.

an effective hot pack salt can release 5850 j of heat to the surroundings. how many grams of licl are needed to release this amo
Montano1993 [528]

4.01 grams of Licl are needed to release this amount of heat

<h3>What does one gram weigh?</h3>

The gram is a unit of mass in the International System of Units (SI) that is equal to one thousandth of a kilogram. It was originally known as the gramme. Gram. This pen cap weighs around one gram. A weight scale like this one may provide a precise mass readout for many different things.

Mass of Licl required to release 5850J of heat to the surroundings.

Let x g Licl required.

Then x g ×∆H = 5850J

x g × 1.46 × 10³ = 5850

x = 5850/ 1.46 × 10³

x = 4.0068

so 4.01g Licl required.
