Answer: B- Matter is composed of very small particles.

Explanation:

a. The particles that make up a substance having different amounts of kinetic energy.

b. Matter is composed of very small particles.

c. Based on the state of matter a substance is in, it has varying particle arrangement.

d. Particles stop moving completely when they are very cold.

The assumptions of KMT:
- Molecules are in constant random motion.

- They undergo elastic collisions; other than collisions.

- Particles do not interact with each other.

- The distance between particles is large compared to their size.

A, C, and D all have something similar to the assumptions that I have listed. B is something completely random and unrelated. (As far as KMT goes.)

What is the mass of 4.02 mol Ba(NO2)2

Answers

Hope this help you;)))

Considering the definition of molar mass, the mass of 4.02 mol Ba(NO₂)₂ is 921.9468 grams.

Molar mass is the mass of one mole of a substance, which can be an element or a compound.

Therefore, knowing the molar mass, the mass can be calculated using the expression:

mass= moles× molar mass

In the periodic table, you can find the molar mass of the elements, also called atomic mass or atomic weight.

To calculate the molecular mass of a compound, also called mass or molecular weight, you must add the molar mass of the elements of the compound multiplied by the number of atoms of each element that make up the compound.

In this case, being the atomic mass:

Ba: 137.34 g/moleN: 14 g/moleO: 16 g/mole

The molecular mass of Ba(NO₂)₂ can be calculated as:

Ba(NO₂)₂= 137.34 g/mole× 2× (14 g/mole +2×16 g/mole)

Ba(NO₂)₂= 229.34 g/mole

Then, the mass of 4.02 mol Ba(NO₂)₂ can be calculated as:

mass= 4.02 moles× 229.34 g/mole

mass= 921.9468 grams

Finally, the mass of 4.02 mol Ba(NO₂)₂ is 921.9468 grams.

if two group in the game are exirting equal ad opposite force the rope,will the rope move?

Answers

Answer:

No.

Explanation:

If the forces are acting on opposite direction, they will cancel out each other. As a result, the object will not move. This type of force is called balanced force. In this type of force the net force acting on an object is equal to 0. Hence, if two groups in the game are exerting equal and opposite force, the rope will not move.

When paper is burned, the mass of the remaining ash is less than the mass of the original paper.
Which statement best explains this result?
0 The ash has less volume than the paper.
O Some of the matter is destroyed during the reaction.
O The mass of the ash cannot be accurately determined.
O Some of the products of the reaction were given off as a gas.

Answers

When paper is burned, the mass of the remaining ash is less than the mass of the original paper because Some of the products of the reaction were given off as a gas.

The postulate of the law of conservation of mass is that mass can not be created or destroyed rather it can be transformed from one form to another.

This means that when ash is left behind after burning paper, the total mass should be the same as was obtained before combustion but it rather weighs less than paper itself. This should never be interpreted to mean that mass was "lost".

Here is what happens, paper is an organic material and burning it in air yields CO2 gas which escapes into the atmosphere. This explains why; when paper is burned, the mass of the remaining ash is less than the mass of the original paper.

Calculate the average atomic mass of a
sample of lead that is 24.1% lead-206
(205.974 amu), 22.1% lead-207 (206.976 amu)
and 53.8% lead 208 (207.977 amu).

Answers

Answer: 207.217 amu

Work:

203.973 amu *(0.014) = 2.855 amu

205.974 amu *(0.241) = 49.639 amu

206.976 amu *(0.221) = 45.741 amu

207.977 amu *(0.524) = 108.979 amu

2.855 + 49.639 + 45.741 + 108.979 = 207.217amu

Explanation:

The average atomic mass has been defined to be the total mass given by the relative abundances and masses of the isotopes. The average atomic mass of lead is 204.359 amu.

What is average atomic mass?

The average atomic mass has been given by the masses and relative proportions and abundances of the isotopes of the elements that differ from the mass of the element in the periodic table. It is the average mass given by the sum of the masses and the abundances.

Given,

Abundance of lead-206 = 24.1%

The abundance of lead-207 = 22.1%

The abundance of lead-208 = 53.8%

Mass of lead-206 = 205.974 amu

Mass of lead-207 = 206.976 amu

Mass of lead-208 = 207.977 amu

The average atomic mass is given as:

= (205.974 × 0.241) + (206.976 × 0.221) + (207.977 × 0.524)

= 49.639 amu + 45.741 amu + 108.979 amu

= 204.359 amu

Therefore, 204.359 amu is the average atomic mass.

What is it weathering, Erosion or deposition

Answers

Answer:

I think the answer is EROSION because it has to do with the movement of sediment.

Explanation:

Hope this helps!

Flood waters moving soil from one location to another is called erosion.

Erosion is the process by which soil, rock, and other materials are transported from one place to another by natural forces such as water, wind, and ice.

In the case of soil being moved by flood waters, the water is the natural force that is causing the erosion. The water is carrying the soil from one location to another, which is a characteristic of erosion. Deposition, on the other hand, is the process by which eroded materials are deposited or laid down in a new location. Deposition occurs when the energy of the transporting medium (such as water or wind) decreases, and the materials being transported are no longer able to be carried.

Therefore, the movement of soil from one location to another due to flood waters is an example of erosion.

He was immensely excited at the news, and in the excess of his feelings invited me up to take a turn with him that night in a scrutiny of the red planet. In spite of all that has happened since, I still remember that vigil very distinctly: the black and silent observatory, the shadowed lantern throwing a feeble glow upon the floor in the corner, the steady ticking of the clockwork of the telescope, the little slit in the roofan oblong profundity with the stardust streaked across it. Ogilvy moved about, invisible but audible. Looking through the telescope, one saw a circle of deep blue and the little round planet swimming in the field.
