The true statements is that nerve cells do not look like skin cells because they make up different organs and have different functions.

Cells are the basic functional and fundamental unit of any living organism.

Each and every cells that are present inside the body have same DNA, but they all have different function and different structures. As nerve cells are present only in the brain and spinal cord part and skin cells are present all over the body.

Hence both the cells are different as they have different functions.

The mole fraction of the sulfur dioxide gas present in a falsk which contains 21.8 g of chlorine gas and 47.8 g of sulfur dioxide gas is 0.708.

Mole fraction of any substance will be calculated by dividing the moles of desired substance by the total moles of the species present in that sample.

Moles can be calculated as:

n = W/M, where

W = given mass

M = molar mass

Moles of 21.8g of chlorine gas = 21.8g / 71g/mol = 0.307mol

Moles of 47.8g of sulphur dioxide gas = 47.8g / 64g/mol = 0.746mol

Mole fraction of sulphur dioxide gas = 0.746 / 0.746+0.307 = 0.708

Hence required mole fraction of sulphur dioxide gas is 0.708.

Answer:

There is no net loss of energy from the collisions.

Explanation:

Gas particles are constantly colliding with each other and the walls of their container. These collisions are elastic; that is, there is no net loss of energy from the collisions. Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container.

because 37 does not end with 5 or 0, so it'd be harder to see if the water temperature is accurate if your thermometer goes up by 5s or 10s. And using D, the one that goes up by 20s is out of the question, it'd be too difficult to read. Using a thermometer that goes up by 1s is just best because you can be positive when the water is at 37°C

Answer:

14 mol O₂

Explanation:

The reaction between CO and O₂ is the following:

CO + O₂ → CO₂

We balance the equation with a coefficient 2 in CO and CO₂ to obtain the same number of O atoms:

2CO + O₂ → 2CO₂

As we can see from the balanced equation, 1 mol of O₂ is required to react with 2 moles of CO. Thus, the conversion factor is 1 mol of O₂/2 mol CO. We multiply the moles of CO by the conversion factor to calculate the moles of O₂ that are required:

28 mol CO x 1 mol of O₂/2 mol CO = 14 mol O₂

We should manage and conserve forest resources in Nepal.

Explanation:

Nepal is the second richest country in natural resources. We should all work together and conserve our natural resources. We can conserve and manage forests in Nepal by the following ways:

1. Proper rules and laws should be made as well as executed by our government.

2. Illegal activities regarding harm of forests and its resources should be totally band.

3. Awareness programmes should be conducted worldwide to aware our citizens regarding conservation of forests.

Taking into account the ideal gas law and the definition of molar mass, the molar mass of a 3.228 g sample of a gas if it occupies 3.21 L at 298 K and 1.25 atm is 19.66 [tex]\frac{g}{moles}[/tex].

An ideal gas is a theoretical gas that is considered to be composed of randomly moving point particles that do not interact with each other. Gases in general are ideal when they are at high temperatures and low pressures.

The pressure, P, the temperature, T, and the volume, V, of an ideal gas, are related by a simple formula called the ideal gas law:

P×V = n×R×T

where P is the gas pressure, V is the volume that occupies, T is its temperature, R is the ideal gas constant, and n is the number of moles of the gas. The universal constant of ideal gases R has the same value for all gaseous substances.

The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.

In this case, you know:

Replacing in the ideal gas law:

1.25 atm× 3.21 L = n× 0.082 [tex]\frac{atmL}{mol K}[/tex]× 298 K

Solving:

n= (1.25 atm× 3.21 L)÷ (0.082 [tex]\frac{atmL}{mol K}[/tex]× 298 K)

n= 0.1642 moles

So, the number of moles in this case are 0.1642 moles.

In this case, you know:

Then, considering the definition of molar mass, it is calculated as:

[tex]molar mass=\frac{3.228 g}{0.1642 moles}[/tex]

Solving:

molar mass= 19.66[tex]\frac{g}{moles}[/tex]

Finally, the molar mass of a 3.228 g sample of a gas if it occupies 3.21 L at 298 K and 1.25 atm is 19.66 [tex]\frac{g}{moles}[/tex].

Answer:

3.99 moles Al₂O₃

Explanation:

The molar mass (g/mol) is used to convert between grams and moles. This value is calculated by taking the individual element molar masses from the periodic table, multiplying them by the corresponding subscripts, then adding them together. Al is 26.98 g/mol and has a subscript of 2. O is 16.00 g/mol and has a subscript of 3. So, the molar mass of Al₂O₃ is 101.96 g/mol.

2(26.98 g/mol) + 3(16.00 g/mol) =  101.96 g/mol

Since it is 101.96 grams PER one mole, the 101.96 is beside grams in the ratio. When setting up the conversion, you want grams in the demoninator (molar mass ratio) to cancel out the grams in the numerator (given value). Since the given number has 3 significant figures, the answer should also have 3 significant figures.

407 grams Al₂O₃          1  mole Al₂O₃
--------------------------  x   --------------------  = 3.99 moles Al₂O₃

Answer:

The 2 ohm branch

Explanation:

Since the resistors are in parallel, they are each connected to the same volatage.   Since   I = V/R    you can see that the one with the smallest resistance will have the greatest current through it .

The water molecules have more kinetic energy and have a greater chance of interacting with (and dissolving) the potassium iodide.

Stirring breaks a solute into smaller pieces which increases its surface area as well as its rate of dissolution. Stirring brings unused portions of the solvent in contact with the solute which allows the solute to dissolve faster.

So we can conclude that option A is the right answer.

When a liquid is heated, the average kinetic energy of its particles will increase.

The ability to do work is called as energy. Work done is product of force and displacement. Energy is of different types as sound energy, kinetic energy, potential energy, electrical energy, light energy etc.

Law of conservation of energy states that energy can neither be created nor destroyed, but it can be transferred from one form to another.

Molecules can move so they show kinetic energy, molecules can be there at many positions so they can show potential energy, molecules can vibrate so they can show sound energy but molecules can only absorb light hence they can't have light energy.

Average kinetic energy = 3KT/2

If temperature increases, kinetic energy also increases.

Therefore, When a liquid is heated, the average kinetic energy of its particles will increase.
