In this simulation, ___________________ will be used to stimulate the axon.
inysia [295]
Voltage is known to be used as a requirement for stimulating an axon. The axon conducts electrical signals away from the nerve cell. The main function of the axons is that it is specifically used to transmit information, in a form of electrical impulse, to the other parts of the body.

A chemist measures the amount of iodine solid produced during an experiment. she finds that 1.6 g of iodine solid is produced. c
Yakvenalex [24]

Mass of iodine solid produced = 1.6 g

Iodine solid has a molecular formula : I2

Atomic mass of iodine = 126.904 g/mol

Therefore, molar mass of I2 solid = 2* 126.904 = 253.808 g/mol

Number of moles of a given substance is the ratio of its mass to the molar mass

# moles of I2 solid = mass of I2 solid/molar mass = 1.6 g/253.808 = 0.00630 moles

Hence, the # moles of iodine solid produced is 0.00630 moles

sweet-ann [11.9K]

Answer:

The physical states that are represented by each graph region are the liquid and the solid, the highest temperature is the liquid and as it freezes it becomes a solid. The particles change because when it's a liquid, it isn't that compact it's just spreading smootly but as it freezes the atoms start to stick together and become compact.

Explanation:

Hope that made sense!

Which of the following is a list of the minimum amount of data needed for determining the molar enthalpy of solution of KCl(s) i
Gre4nikov [31]

Answer:

 (C) Mass of KCl(s), mass of H20, initial temperature of the water, and final temperature of the solution

Explanation:

molar enthalpy of solution of KCl(s) is heat evolved or absorbed when one mole of KCl is dissolved in water to make pure solution . The heat evolved or absorbed can be calculated by the following relation.

Q = msΔt where m is mass of solution or water , s is specific heat and Δt is change in temperature of water .

So data required is mass of water or solution , initial and final temperature of solution , specific heat of water is known .

Now to know molar heat , we require mass of solute or KCl dissolved to know heat heat absorbed or evolved by dissolution of one mole of solute .

What is the work done when a force of 5 N is applied to a ball and it moves 8000 cm?
kolezko [41]

Answer:

Explanation:Given;

applied force, F = 8000 N

time of force application, t = 15 s

Work done is given as the product of force and displacement. Since the car is unable to move, then the displacement is zero and the work done is zero.

Work done = Force x displacement

Work done = 8000 N x 0

Work done = 0

Therefore, the work done is zero.
