Answer:

Molecules in the water move in a circular motion

Explanation:

Because of its circular motion it causes the waves to look like open circles which makes it easy for people to surf on

Water molecules move up and forward, down and back, in an overall circular motion in the wave. Therefore, option A is correct.

Circular motion is defined as the movement of an object while rotating in a circle. Circular motion can be uniform or asymmetric.

The angular rate of rotation and speed are constant in uniform circular motion, but the rate of rotation changes in non-uniform circular motion.

This means that circular motion can occur only if there is a "center seeking" force present; otherwise, things will travel in a straight line.

Within the wave, the water molecules move in a circular motion. Each water particle moves in a complete circle during a single wave period. The circle traced by a water particle on the ocean surface as a wave passes a given point has a diameter equal to the height of the wave.

Thus, option A is correct.

v=(30.0cm)(20.0cm)(50.0cm)=30,000cm^3

The transfer of energy between systems through work is the expansion of gas in a steam engine. By doing work or by transferring heat, energy can be transferred. Therefore, option A is correct option.

Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy requirement is necessary to move any object so work has to be done by the gas to the piston.

Heat can be transferred by three ways radiation, convention or conduction. In conduction, direct contact of two body is necessary for transfer of molecules. When we touch a shopping cart in the grocery store parking lot, then conduction is the process by which heat is transferred between our hand and the handle.

Therefore, the option A is correct option that is conduction.

The percent yield of the reaction would be 85.64%

From the balanced equation of the reaction:

[tex]9 O_2 + 2 Sb_2S_3 ---> 6 SO_2 + Sb_4O_6[/tex]

Mole ratio of Sb2S3 to Sb4O6 is 2:1

Mole of 98.7g Sb2S3 = 98.7/339.7

                                   = 0.29 moles

Equivalent mole of Sb4O6 = 0.29/2

                                            = 0.145 moles

Mass of 0.145 Sb4O6 = 0.145 x 583

                                     = 84.535 g

Percent yield = yield/theoretical yield x 100

                       = 72.4/84.535 x 100

Answer:

1.51 x 10^23 atoms of Ar

Explanation:

Start out with what you're given.

10.0 g of Ar/1 * 1 mol/39.948 g Ar * 6.022*10^23 atoms/1 mol

(It's easier if you write it out.)

You always want to start out w/ what you're given and continue your unit conversions from there. Since you started out with grams of Argon, you want grams of Argon on the bottom to cancel it out. Once you found the unit conversion: 1 mol/39.948 g Ar (molar mass of Ar), now it's time to convert to atoms. Since 1 mol is up on top, put 1 mol on the bottom. Considering you're looking for atoms, use Avagradro's number: 6.022*10^23.

Once simplified, you should get 1.51 x 10^23 atoms of Ar.

Wind and Erosion lead to Washing away of top soil.

Erosion is the process that lead to the washing away of top soil leading to loss of nutrient, holes and many more.

The agents of erosion include wind, water and so on.

Strong wind will lead to the top soil to be remove when it is blowing. Water also when is is flowing turbulently maybe when rain fall can lead to loss of top soil.

Answer:

A) The atoms of the reactants unbond, rearrange and then rebond to form the products

Explanation:

Using method of elimination:

A) The atoms of the reactants unbond, rearrange and then rebond to form the products

This is the correct option. Chemical reactions involves breaking and forming of new bonds.

B) Some atoms disappear while others multiply to form the products

This option is incorrect. Atoms do not disappear

C) The atoms of the reactants always stay together to form the products

This option is incorrect. The bonds between the atoms in the reactants must first be broken before products can be formed.

D) New atoms are formed which combine to make the products

This option is incorrect. Atoms do not just form out of nowhere.

The net force acting on the box is 15 N which is the difference of the two acting forces and the  box shifts to the right in the direction in which greater amount of force is applied.

Force is defined as a cause which is capable of changing the motion of an object. It can cause an object which has mass to change it's velocity. It is also simply a push or a pull . It has both magnitude as well as direction.Hence, it is a vector quantity.

It has SI units of Newton and is represented by'F'.Newton's second law states that force which acts on an object is equal to momentum which changes with time. If mass of object is constant, acceleration is directly proportional to net force acting on an object.

The concepts which related to force are thrust and torque .Thrust increases the velocity of an object and torque produces change in rotational speed of an object.

Answer:

A balanced ionic equation shows the reacting ions in a chemical reaction. These equations can be used to represent what happens in precipitation reactions or displacement reactions.

Precipitation reactions

In a typical precipitation reaction, two soluble reactants form an insoluble product and a soluble product.

For example, silver nitrate solution reacts with sodium chloride solution. Insoluble solid silver chloride and sodium nitrate solution form:

AgNO3(aq) + NaCl(aq) → AgCl(s) + NaNO3(aq)

The Na+ ions and NO3- ions remain separate in the sodium nitrate solution and do not form a precipitate. Ions that remain essentially unchanged during a reaction are called spectator ions.This means these can be ignored when writing the ionic equation. Only how the solid silver chloride forms is needed to be shown:

Ag+(aq) + Cl-(aq) → AgCl(s)

In a balanced ionic equation:

the number of positive and negative charges is the same

the numbers of atoms of each element on the left and right are the same

Displacement reactions

Displacement reactions take place when a reactive element displaces a less reactive element from one of its compounds.

A common type of displacement reaction takes place when a reactive metal reacts with the salt of a less reactive metal. For example, copper reacts with silver nitrate solution to produce silver and copper(II) nitrate solution:

2AgNO3(aq) + Cu(s) → 2Ag(s) + Cu(NO3)2(aq)

In this reaction, the NO3- ions remain in the solution and do not react - they are the spectator ions in this reaction. So, they can be removed from the ionic equation:

2Ag+(aq) + Cu(s) → 2Ag(s) + Cu2+(aq)

Question

Explain why this ionic equation is balanced:

Ba2+(aq) + SO42-(aq) → BaSO4(s)

Hide answer

There are the same numbers of atoms of each element on both sides of the equation. The total charge on both sides is also the same (zero).

Question

Balance this ionic equation, which represents the formation of a silver carbonate precipitate:

Ag+(aq) + CO32-(aq) → Ag2CO3(s)

Hide answer

2Ag+(aq) + CO32-(aq) → Ag2CO3(s)

Question

Balance this ionic equation, which represents the displacement of iodine from iodide ions by chlorine:

Cl2(aq) + I-(aq) → I2(aq) + Cl-(aq)

7. Concave and convex mirrors are called spherical mirrors because they are both made from the sphere. The difference between the two (in the simplest terms) is that diminished images form in convex mirrors while enlarged images form in concave mirrors.

8. The word ambulance is written inverted on an ambulance is because when a driver is driving and sees an ambulance in their rearview mirror, they can see the word ambulance the correct way. Otherwise the word ambulance would be backwards in the mirror. Thats why they write it backwards.

9. A plane mirror forms the image, object, etc, the same exact size that it is. The mirror can be small or large the size of the image will stay the same. So the difference between the object in a small and large plane mirror is none, there is no difference.

10. Car rearview mirrors are curved. This is to give a wider viewing angle. Flat surface mirrors give an accurate reflection. since the rearview mirrors are not flat, they are curved, they are less accurate, so thats why they have a warning label.

11. The sun emits the color of white. And as we know the color white consists of all colors. We can test this by putting the sunlight through a prism. since different colors of light travels at different speeds in the glass we cand see the light 'bent' .

12. Solar cookers use concave mirrors. This is because the mirror reflects the sunlight to a focal, 'center,' point. This center point will eventually heat up very, very hot.
