The largest particle that can generally be transported by a stream moving at 200 centimeters per second is a cobble.

So, the correct answer is option 2.

A cobble is a rounded rock fragment larger than a pebble but smaller than a boulder. It usually ranges in size from 64 to 256 millimeters in diameter. The velocity of a stream is a critical factor in determining the size of the particles that can be transported by the water. As the velocity of the stream increases, it can carry larger particles.

However, there is a limit to the size of the particles that can be transported, and a stream moving at 200 centimeters per second can carry a maximum particle size of a cobble. Anything larger, such as a boulder, would require a much stronger current to transport.

Hence, the answer of the question is option 2

Answer:

b. proton

Explanation:

The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1.

Answer:

Chemical reaction

Explanation:

This process is called a chemical reaction. A chemical reaction is where atoms are rearranged to create various compounds, so the atoms can either be formed or broken.

For example, in this equation for the formation of water:

2H2(g) + O2(g) → 2H2O(l)

Here hydrogen and oxygen both combine to form water. This new compound, water, that has formed is what makes it a chemical reaction.

In this equation for the decomposition of calcium carbonate:

CaCO3(s) → CaO(s)+ CO2(g)

Here, CaCO3 has been broken down into CaO and CO2, which takes place as a chemical reaction.

The amount of drink that needs to evaporate to reach a drinkable temperature will vary based on the specific circumstances.

To determine how much of the drink must evaporate for it to reach the drinkable temperature, we need more information about the specific drink and its initial temperature. However, in general, evaporation is a cooling process as it removes heat from the liquid. So, if a drink is initially too hot, some of it will need to evaporate for it to reach a drinkable temperature. The amount that needs to evaporate depends on factors such as the volume and temperature of the drink, as well as the desired drinkable temperature. To calculate the specific amount, you would need to consider the heat transfer properties of the liquid, the surrounding environment, and the time available for evaporation. In conclusion, the amount of drink that needs to evaporate to reach a drinkable temperature will vary based on the specific circumstances.

The molarity of the sodium hydroxide that contains 125 g NaOH in 2.00 L of solution is 1.5625 M

First, we shall obtain the number of mole of NaOH in the solution. This is shown below:

Mole = mass / molar mass

Mole of NaOH = 125 / 40

Mole of NaOH = 3.125 moles

Finally, we shall determine the molarity of the sodium hydroxide solution as follow:

Molarity = mole / volume

Molarity = 3.125 / 2

Molarity = 1.5625 M

Thus, the molarity of the sodium hydroxide is 1.5625 M

The mass of NaNO3 would be needed to make a saturated solution in 200 mL of water at 80°C is 296g.

A solubility curve is the line drawn on a graph to depict the relationship between temperature and a substance's solubility at various temperatures. Where the solution is saturated is shown by the lines on the solubility curve. Anywhere below the lines, there is still room for more solute to dissolve because the solution is not saturated.

Solubility of NaNO3 in water at 80°C is 148g/100mL.

The quantity of water at 80°C = 200 mL

Therefore, the weight of NaNO3 = 148g/100mL x 200mL

                                                         => 296g

A saturated solution is one that has as much solute in it as can be dissolved under the circumstances in which it is present. Seawater, Epsom bath salts, carbonated beverages, and powdered beverages are a few examples of saturated solutions.

Answer:

The answer is false

I say this because when Things get hot the molecules move faster but when things get cold they slow down so at the temperature decreases that means the motte water molecules are slowing down therefore it is not increasing

As the temperature of the system decreases, the motion of the water molecules increases. This statement is true.

As the temperature rises, the particles move faster as they gain kinetic energy, resulting in higher collision rates and a faster rate of diffusion.

Energy is transferred when water molecules collide. Energy is destroyed as the system's temperature falls. The kinetic energy of water molecules increases as heat is added to a system. The motion of the water molecules increases as the temperature of the system decreases.

Because when things get hot, the molecules move faster, but when things get cold, they slow down, so when the temperature drops, the  water molecules slow down, so it increases.

Thus, As the temperature of the system decreases, the motion of the water molecules increases.

Explanation:

An oxygen atom has 8 protons and 8 neutrons. An oxygen atom is represented by the symbol "O" and has an atomic number of 8.

The atomic number corresponds to the number of protons in the nucleus of an atom. Since protons have a positive charge, the atomic number also determines the element's identity. In the case of oxygen, its atomic number is 8, indicating that it has 8 protons.

The mass number of an oxygen atom is approximately 16. The mass number represents the sum of protons and neutrons in the atom's nucleus. To calculate the number of neutrons, we subtract the number of protons (8) from the mass number (16). Therefore, an oxygen atom has 8 neutrons.

To properly measure 20 ml of water, the 20 ml mark of the graduated cylinder must be at the meniscus.

We measure at the meniscus for what reason?

To have the "actual" volume be what is marked, the mark must be placed where the bottom of the meniscus should be on the glass. Therefore, by taking measurements from the bottom of the meniscus, you are harmonizing your measurement process with the method used to calibrate the markings on the glass in the first place.

The meniscus is what?

When a molecular substance (water, of course) comes into contact with another material, the surface forms a meniscus. You may imagine that happening with water when it adheres to the interior of a glass.

The periodic table with masses is very useful as the atomic mass is the average number of protons and neutrons in atoms of a chemical elements, which allows for the natural abundances of the element's isotopes.

Generally, atomic mass of an element is defined as the number of times an atom of that element which is heavier than an atom of carbon taken as 12. Basically, one atomic mass unit is equal to one-twelfth of the mass of an atom of carbon 12 isotope.

In the modern periodic table atomic number is present at the upper left, or number of protons. And in the middle the letter is the symbol used for the element (e.g., H). And below is the relative atomic mass, as calculated for the isotopes found naturally on Earth. Finally at the very bottom is the name of the element (e.g., hydrogen).

2 liters of 72 octane gasoline should be mixed with (12 - 2) = 10 liters of 84 octane gasoline to obtain 12 liters of 82 octane gasoline.

Let's assume x liters of 72 octane gasoline are mixed with (12 - x) liters of 84 octane gasoline to obtain 12 liters of 82 octane gasoline.

To find the solution, we can set up an equation based on the octane content: (72x + 84(12 - x)) / 12 = 82

Now, let's solve for x:

72x + 84(12 - x) = 82 * 12

72x + 1008 - 84x = 984

-12x = 984 - 1008

-12x = -24

x = (-24) / (-12)
